Example 2: Purchase Propensity Modeling for Targeted Offers
An e-commerce company wants to increase sales by targeting customers who are most likely to purchase a specific product. They can build a purchase propensity model using historical customer data (browsing history, purchase history, demographics, email engagement) and machine learning algorithms. The model predicts the likelihood of each customer purchasing a specific product (e.g., a new laptop). Customers with a high purchase propensity are then targeted with personalized email campaigns featuring the product, special offers, and compelling reasons to buy.

Before implementing predictive segmentation, it’s important to start with simpler segmentation strategies and gradually incorporate more advanced techniques as you collect more data and refine your models. Additionally, ensuring data privacy and transparency is paramount when working with customer data.

By embracing advanced behavioral segmentation strategies, you can transform your email marketing from a generic broadcast medium into a highly personalized and effective communication channel. This targeted approach not only improves your ROI but also builds stronger relationships with your subscribers, fostering customer loyalty and driving long-term growth.

This model outputs a churn probability for each customer. Those with a high probability are added to a “high churn risk” segment and are sent targeted emails with special offers, personalized support, or exclusive content to incentivize them to stay. The key is to intervene *before* they actually churn.

Example 1: Churn Prediction and Prevention

A telco company wants to prevent customer churn. They can build a churn prediction model using historical customer data (demographics, usage patterns, billing information, customer service interactions) and machine learning algorithms.

#Python example using scikit-learn for churn prediction

import pandas as pd
from sklearn.model_selection import train_test_split
from sklearn.ensemble import GradientBoostingClassifier
from sklearn.metrics import accuracy_score

# Load customer data
data = pd.read_csv('customer_data.csv')

# Prepare data (feature engineering, cleaning, etc. -  omitted for brevity)
X = data[['usage', 'billing_amount', 'customer_service_calls']]  #Example features
y = data['churned'] #Target variable - True/False

# Split data into training and testing sets
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

# Train a Gradient Boosting Classifier model
model = GradientBoostingClassifier(n_estimators=100, learning_rate=0.1, max_depth=3, random_state=42)
model.fit(X_train, y_train)

# Make predictions on the test set
y_pred = model.predict(X_test)

# Evaluate the model
accuracy = accuracy_score(y_test, y_pred)
print(f"Accuracy: {accuracy}")

#Predict churn probability for each customer
data['churn_probability'] = model.predict_proba(X)[:, 1] #Probability of churning

#Identify customers with high churn probability
high_churn_risk = data[data['churn_probability'] > 0.7]['customer_id'].tolist() #Threshold of 0.7

#Now high_churn_risk contains the list of customer_ids at high risk of churn.  Feed this list into your email campaign.

The choice of algorithm depends on the specific prediction you’re trying to make and the nature of your data.

Applications of Predictive Segmentation

Here are some ways you can use predictive behavioral segmentation in your email marketing:

Churn Prediction: Identify subscribers who are likely to churn and proactively offer them incentives to stay.
Purchase Propensity Modeling: Predict which subscribers are most likely to make a purchase and target them with personalized offers.
Product Recommendation Engines: Recommend products based on a subscriber’s predicted interests and purchase history.
Personalized Content Recommendations: Recommend blog posts, articles, or other content based on a subscriber’s predicted interests.
Optimal Send Time Prediction: Determine the best time to send emails to each subscriber based on their past engagement patterns.

#Now high_churn_risk contains the list of customer_ids at high risk of churn.  Feed this list into your email campaign.

Where X, Y, and Z are thresholds you define based on your data and goals (e.g., opened at least 5 emails, clicked at least 2 links, and last activity within the last 30 days).

Example 3: Optimizing Content Based on CTR
Analyze which types of content generate the highest CTR among your subscribers. Use this data to create more compelling and relevant email campaigns. For instance, if you notice that subscribers are more likely to click on emails with video content, incorporate more videos into your email marketing strategy. A/B testing different subject lines, email designs, and calls to action can also help you improve your CTR.

Expert Tip: “Don’t be afraid to prune your email list. It’s better to have a smaller, highly engaged list than a large, inactive one. A healthy list improves your sender reputation and deliverability.”

Predictive Behavioral Segmentation

Predictive behavioral segmentation takes email marketing to the next level by using machine learning algorithms to anticipate future customer behavior. Instead of just reacting to past actions, you can proactively target subscribers based on their predicted likelihood to purchase, churn, or engage with specific content. This requires sophisticated data analysis and the use of predictive modeling techniques, but the potential payoff in terms of personalization and ROI is significant. This involves understanding the ‘why’ behind the behavior, not just the ‘what’.

Predictive Modeling Techniques

Several machine learning techniques can be used for predictive behavioral segmentation:

Regression Analysis: Used to predict continuous variables like purchase value or customer lifetime value.
Classification Algorithms: Used to predict categorical variables like churn risk or product interest. (e.g., Logistic Regression, Support Vector Machines, Random Forests)
Clustering Algorithms: Used to group subscribers into segments based on similarities in their behavior. (e.g., K-Means Clustering)
Time Series Analysis: Used to predict future trends based on historical data.

The choice of algorithm depends on the specific prediction you’re trying to make and the nature of your data.

If they still don’t engage after the re-engagement campaign, consider removing them from your list to improve your sender reputation and reduce your email marketing costs. Maintaining a clean and engaged list is crucial for deliverability.

Example 2: Rewarding Active Subscribers
Send a thank-you email to your most active subscribers, offering them exclusive content, early access to new products, or a special discount.

// Example query to identify active subscribers (Conceptual)
SELECT subscriber_id
FROM email_activity
WHERE open_count >= X AND click_count >= Y
AND last_activity_date >= Z
GROUP BY subscriber_id;

Where X, Y, and Z are thresholds you define based on your data and goals (e.g., opened at least 5 emails, clicked at least 2 links, and last activity within the last 30 days).

Example 3: Cross-selling and Upselling
Recommend related products or upgrades based on a customer’s previous purchases. For instance, if a customer bought a camera, you could send them emails featuring camera lenses, tripods, or other accessories. Amazon’s “Frequently Bought Together” is a prime example of this in action.

Email Engagement Segmentation

Email engagement segmentation categorizes subscribers based on how they interact with your email campaigns. This goes beyond simply knowing if someone is on your list; it analyzes how active and responsive they are to your emails. Metrics like open rates, click-through rates (CTR), and bounce rates provide valuable insights into subscriber interest and engagement levels. By understanding these patterns, you can optimize your email deliverability, improve your content, and personalize your messaging to re-engage inactive subscribers and reward active ones. This allows you to prune your list and improve sender reputation.

Key Email Engagement Metrics

The core metrics to track for email engagement segmentation are:

Open Rate: The percentage of subscribers who open your emails.
Click-Through Rate (CTR): The percentage of subscribers who click on a link in your email.
Bounce Rate: The percentage of emails that fail to deliver. Hard bounces indicate invalid email addresses, while soft bounces indicate temporary delivery issues.
Unsubscribe Rate: The percentage of subscribers who unsubscribe from your email list.
Complaint Rate: The percentage of subscribers who mark your email as spam.

Monitoring these metrics helps you understand the health of your email list and the effectiveness of your email campaigns.

Segmenting Based on Email Engagement

Here are some common email engagement segments you can create:

Active Subscribers: Subscribers who consistently open and click on your emails.
Inactive Subscribers: Subscribers who haven’t opened or clicked on your emails in a specific timeframe.
Engaged But Not Converting: Subscribers who open and click on your emails but haven’t made a purchase.
Unengaged Subscribers: Subscribers who rarely open or click on your emails.
High-Value Engagers: Subscribers who frequently engage with your emails and have also made purchases.

Example 1: Re-engaging Inactive Subscribers
Create a re-engagement campaign for subscribers who haven’t opened an email in the last 90 days. This campaign could include:

A personalized email asking if they still want to receive emails from you.
An offer of a discount or a free gift.
A chance to update their email preferences.

// Example query to identify active subscribers (Conceptual)
SELECT subscriber_id
FROM email_activity
WHERE open_count >= X AND click_count >= Y
AND last_activity_date >= Z
GROUP BY subscriber_id;

Where X, Y, and Z are thresholds you define based on your data and goals (e.g., opened at least 5 emails, clicked at least 2 links, and last activity within the last 30 days).

Churn Prediction: Identify subscribers who are likely to churn and proactively offer them incentives to stay.
Purchase Propensity Modeling: Predict which subscribers are most likely to make a purchase and target them with personalized offers.
Product Recommendation Engines: Recommend products based on a subscriber’s predicted interests and purchase history.
Personalized Content Recommendations: Recommend blog posts, articles, or other content based on a subscriber’s predicted interests.
Optimal Send Time Prediction: Determine the best time to send emails to each subscriber based on their past engagement patterns.

Example 1: Churn Prediction and Prevention

#Python example using scikit-learn for churn prediction

import pandas as pd
from sklearn.model_selection import train_test_split
from sklearn.ensemble import GradientBoostingClassifier
from sklearn.metrics import accuracy_score

# Load customer data
data = pd.read_csv('customer_data.csv')

# Prepare data (feature engineering, cleaning, etc. -  omitted for brevity)
X = data[['usage', 'billing_amount', 'customer_service_calls']]  #Example features
y = data['churned'] #Target variable - True/False

# Split data into training and testing sets
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

# Train a Gradient Boosting Classifier model
model = GradientBoostingClassifier(n_estimators=100, learning_rate=0.1, max_depth=3, random_state=42)
model.fit(X_train, y_train)

# Make predictions on the test set
y_pred = model.predict(X_test)

# Evaluate the model
accuracy = accuracy_score(y_test, y_pred)
print(f"Accuracy: {accuracy}")

#Predict churn probability for each customer
data['churn_probability'] = model.predict_proba(X)[:, 1] #Probability of churning

#Identify customers with high churn probability
high_churn_risk = data[data['churn_probability'] > 0.7]['customer_id'].tolist() #Threshold of 0.7

#Now high_churn_risk contains the list of customer_ids at high risk of churn.  Feed this list into your email campaign.

The pandas code identifies those users whose last purchase was more than 6 months ago and allows you to feed that list to your email marketing platform to initiate a re-engagement campaign.

Email Engagement Segmentation

Key Email Engagement Metrics

The core metrics to track for email engagement segmentation are:

Open Rate: The percentage of subscribers who open your emails.
Click-Through Rate (CTR): The percentage of subscribers who click on a link in your email.
Bounce Rate: The percentage of emails that fail to deliver. Hard bounces indicate invalid email addresses, while soft bounces indicate temporary delivery issues.
Unsubscribe Rate: The percentage of subscribers who unsubscribe from your email list.
Complaint Rate: The percentage of subscribers who mark your email as spam.

Monitoring these metrics helps you understand the health of your email list and the effectiveness of your email campaigns.

Segmenting Based on Email Engagement

Here are some common email engagement segments you can create:

Active Subscribers: Subscribers who consistently open and click on your emails.
Inactive Subscribers: Subscribers who haven’t opened or clicked on your emails in a specific timeframe.
Engaged But Not Converting: Subscribers who open and click on your emails but haven’t made a purchase.
Unengaged Subscribers: Subscribers who rarely open or click on your emails.
High-Value Engagers: Subscribers who frequently engage with your emails and have also made purchases.

Example 1: Re-engaging Inactive Subscribers
Create a re-engagement campaign for subscribers who haven’t opened an email in the last 90 days. This campaign could include:

A personalized email asking if they still want to receive emails from you.
An offer of a discount or a free gift.
A chance to update their email preferences.

Example 2: Rewarding Active Subscribers
Send a thank-you email to your most active subscribers, offering them exclusive content, early access to new products, or a special discount.

// Example query to identify active subscribers (Conceptual)
SELECT subscriber_id
FROM email_activity
WHERE open_count >= X AND click_count >= Y
AND last_activity_date >= Z
GROUP BY subscriber_id;

Where X, Y, and Z are thresholds you define based on your data and goals (e.g., opened at least 5 emails, clicked at least 2 links, and last activity within the last 30 days).

Predictive Behavioral Segmentation

Predictive Modeling Techniques

Several machine learning techniques can be used for predictive behavioral segmentation:

Regression Analysis: Used to predict continuous variables like purchase value or customer lifetime value.
Classification Algorithms: Used to predict categorical variables like churn risk or product interest. (e.g., Logistic Regression, Support Vector Machines, Random Forests)
Clustering Algorithms: Used to group subscribers into segments based on similarities in their behavior. (e.g., K-Means Clustering)
Time Series Analysis: Used to predict future trends based on historical data.

The choice of algorithm depends on the specific prediction you’re trying to make and the nature of your data.

#Now high_churn_risk contains the list of customer_ids at high risk of churn.  Feed this list into your email campaign.

The result of this query would give you the `customer_id` of your most valuable customers. You can then use this list to create a segment in your email marketing platform and target them with special promotions.

Example 2: Re-engaging Lapsed Customers
Send a targeted email campaign to customers who haven’t made a purchase in the last 6 months. Offer them a discount code or a free gift with their next purchase.

//Example using python and pandas

import pandas as pd
from datetime import datetime, timedelta

#Assume dataframe 'orders' contains customer_id and order_date

cutoff_date = datetime.now() - timedelta(days=180) #6 months ago

lapsed_customers = orders.groupby('customer_id')['order_date'].max()
lapsed_customers = lapsed_customers[lapsed_customers < cutoff_date].index.tolist()
#lapsed_customers now contains a list of customer_ids

These metrics can be combined to create more sophisticated segments. For example, you could segment customers based on their RFM (Recency, Frequency, Monetary Value) score.

Segmenting Based on Purchase History

Here are some examples of purchase behavior segments you can create:

High-Value Customers: Customers with high monetary value and frequent purchases.
Repeat Customers: Customers who have made multiple purchases.
First-Time Buyers: Customers who have made their first purchase.
Lapsed Customers: Customers who haven’t made a purchase in a specific timeframe.
Product-Specific Customers: Customers who have purchased a specific product or product category.

Example 1: Rewarding High-Value Customers
Identify your top 10% of customers based on their CLTV. Send them exclusive offers, early access to new products, or personalized thank-you notes.

// SQL example to identify high-value customers (simplified)
SELECT customer_id, SUM(order_total) AS total_spent
FROM orders
GROUP BY customer_id
ORDER BY total_spent DESC
LIMIT 0.1 * (SELECT COUNT(*) FROM customers); //Top 10 percent

//Example using python and pandas

import pandas as pd
from datetime import datetime, timedelta

#Assume dataframe 'orders' contains customer_id and order_date

cutoff_date = datetime.now() - timedelta(days=180) #6 months ago

lapsed_customers = orders.groupby('customer_id')['order_date'].max()
lapsed_customers = lapsed_customers[lapsed_customers < cutoff_date].index.tolist()
#lapsed_customers now contains a list of customer_ids

GROUP BY subscriber_id;

Where X, Y, and Z are thresholds you define based on your data and goals (e.g., opened at least 5 emails, clicked at least 2 links, and last activity within the last 30 days).

Predictive Behavioral Segmentation

Predictive Modeling Techniques

Several machine learning techniques can be used for predictive behavioral segmentation:

Regression Analysis: Used to predict continuous variables like purchase value or customer lifetime value.
Classification Algorithms: Used to predict categorical variables like churn risk or product interest. (e.g., Logistic Regression, Support Vector Machines, Random Forests)
Clustering Algorithms: Used to group subscribers into segments based on similarities in their behavior. (e.g., K-Means Clustering)
Time Series Analysis: Used to predict future trends based on historical data.

The choice of algorithm depends on the specific prediction you’re trying to make and the nature of your data.

Applications of Predictive Segmentation

Here are some ways you can use predictive behavioral segmentation in your email marketing:

Churn Prediction: Identify subscribers who are likely to churn and proactively offer them incentives to stay.
Purchase Propensity Modeling: Predict which subscribers are most likely to make a purchase and target them with personalized offers.
Product Recommendation Engines: Recommend products based on a subscriber’s predicted interests and purchase history.
Personalized Content Recommendations: Recommend blog posts, articles, or other content based on a subscriber’s predicted interests.
Optimal Send Time Prediction: Determine the best time to send emails to each subscriber based on their past engagement patterns.

Example 1: Churn Prediction and Prevention

#Python example using scikit-learn for churn prediction

import pandas as pd
from sklearn.model_selection import train_test_split
from sklearn.ensemble import GradientBoostingClassifier
from sklearn.metrics import accuracy_score

# Load customer data
data = pd.read_csv('customer_data.csv')

# Prepare data (feature engineering, cleaning, etc. -  omitted for brevity)
X = data[['usage', 'billing_amount', 'customer_service_calls']]  #Example features
y = data['churned'] #Target variable - True/False

# Split data into training and testing sets
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

# Train a Gradient Boosting Classifier model
model = GradientBoostingClassifier(n_estimators=100, learning_rate=0.1, max_depth=3, random_state=42)
model.fit(X_train, y_train)

# Make predictions on the test set
y_pred = model.predict(X_test)

# Evaluate the model
accuracy = accuracy_score(y_test, y_pred)
print(f"Accuracy: {accuracy}")

#Predict churn probability for each customer
data['churn_probability'] = model.predict_proba(X)[:, 1] #Probability of churning

#Identify customers with high churn probability
high_churn_risk = data[data['churn_probability'] > 0.7]['customer_id'].tolist() #Threshold of 0.7

#Now high_churn_risk contains the list of customer_ids at high risk of churn.  Feed this list into your email campaign.

This targeted approach is much more effective than sending them generic marketing emails.

Purchase Behavior Segmentation

Purchase behavior segmentation focuses on categorizing subscribers based on their past purchasing history. This includes factors like frequency of purchases, average order value, products purchased, and recency of purchase. Understanding these patterns allows you to create personalized offers, loyalty programs, and product recommendations that cater to individual customer needs and preferences. It’s a powerful way to increase customer lifetime value and drive repeat business.

Key Purchase Behavior Metrics

To effectively segment based on purchase behavior, you need to track and analyze key metrics. Here are some of the most important:

Recency: How recently did the customer make a purchase?
Frequency: How often does the customer make purchases?
Monetary Value: How much money has the customer spent in total?
Average Order Value: What is the average amount the customer spends per order?
Product Categories Purchased: What types of products does the customer typically buy?
Customer Lifetime Value (CLTV): A prediction of the net profit attributed to the entire future relationship with a customer.

These metrics can be combined to create more sophisticated segments. For example, you could segment customers based on their RFM (Recency, Frequency, Monetary Value) score.

Segmenting Based on Purchase History

Here are some examples of purchase behavior segments you can create:

High-Value Customers: Customers with high monetary value and frequent purchases.
Repeat Customers: Customers who have made multiple purchases.
First-Time Buyers: Customers who have made their first purchase.
Lapsed Customers: Customers who haven’t made a purchase in a specific timeframe.
Product-Specific Customers: Customers who have purchased a specific product or product category.

Example 1: Rewarding High-Value Customers
Identify your top 10% of customers based on their CLTV. Send them exclusive offers, early access to new products, or personalized thank-you notes.

// SQL example to identify high-value customers (simplified)
SELECT customer_id, SUM(order_total) AS total_spent
FROM orders
GROUP BY customer_id
ORDER BY total_spent DESC
LIMIT 0.1 * (SELECT COUNT(*) FROM customers); //Top 10 percent

//Example using python and pandas

import pandas as pd
from datetime import datetime, timedelta

#Assume dataframe 'orders' contains customer_id and order_date

cutoff_date = datetime.now() - timedelta(days=180) #6 months ago

lapsed_customers = orders.groupby('customer_id')['order_date'].max()
lapsed_customers = lapsed_customers[lapsed_customers < cutoff_date].index.tolist()
#lapsed_customers now contains a list of customer_ids

#Integrate with email marketing platform to segment and send campaign

The pandas code identifies those users whose last purchase was more than 6 months ago and allows you to feed that list to your email marketing platform to initiate a re-engagement campaign.

Email Engagement Segmentation

Key Email Engagement Metrics

The core metrics to track for email engagement segmentation are:

Open Rate: The percentage of subscribers who open your emails.
Click-Through Rate (CTR): The percentage of subscribers who click on a link in your email.
Bounce Rate: The percentage of emails that fail to deliver. Hard bounces indicate invalid email addresses, while soft bounces indicate temporary delivery issues.
Unsubscribe Rate: The percentage of subscribers who unsubscribe from your email list.
Complaint Rate: The percentage of subscribers who mark your email as spam.

Monitoring these metrics helps you understand the health of your email list and the effectiveness of your email campaigns.

Segmenting Based on Email Engagement

Here are some common email engagement segments you can create:

Active Subscribers: Subscribers who consistently open and click on your emails.
Inactive Subscribers: Subscribers who haven’t opened or clicked on your emails in a specific timeframe.
Engaged But Not Converting: Subscribers who open and click on your emails but haven’t made a purchase.
Unengaged Subscribers: Subscribers who rarely open or click on your emails.
High-Value Engagers: Subscribers who frequently engage with your emails and have also made purchases.

Example 1: Re-engaging Inactive Subscribers
Create a re-engagement campaign for subscribers who haven’t opened an email in the last 90 days. This campaign could include:

A personalized email asking if they still want to receive emails from you.
An offer of a discount or a free gift.
A chance to update their email preferences.

Example 2: Rewarding Active Subscribers
Send a thank-you email to your most active subscribers, offering them exclusive content, early access to new products, or a special discount.

// Example query to identify active subscribers (Conceptual)
SELECT subscriber_id
FROM email_activity
WHERE open_count >= X AND click_count >= Y
AND last_activity_date >= Z
GROUP BY subscriber_id;

Where X, Y, and Z are thresholds you define based on your data and goals (e.g., opened at least 5 emails, clicked at least 2 links, and last activity within the last 30 days).

#Now high_churn_risk contains the list of customer_ids at high risk of churn.  Feed this list into your email campaign.

Example: Targeting Blog Readers
If a user frequently visits your blog posts about “SEO tips,” you can add them to a segment called “SEO Enthusiasts.” You could then send them targeted emails with:

New blog posts about SEO
Invitations to SEO webinars
Offers for SEO tools or services

This targeted approach is much more effective than sending them generic marketing emails.

Advanced Behavioral Segmentation Strategies for Email Marketing

Email marketing thrives on relevance. Generic, mass emails are increasingly ineffective. This article dives deep into behavioral segmentation, a powerful strategy that allows you to tailor your email campaigns based on your subscribers’ actions and engagement. We’ll explore advanced techniques to personalize your messaging, boost engagement, and ultimately drive conversions by understanding and reacting to how your audience interacts with your brand.

Website Activity Segmentation

Predictive Behavioral Segmentation

Website Activity Segmentation

Website activity segmentation involves tracking and categorizing your email subscribers based on their interactions with your website. This data provides valuable insights into their interests, needs, and stage in the customer journey. By understanding what pages they visit, the content they consume, and the actions they take (or don’t take) on your site, you can create highly targeted email campaigns that resonate with their specific interests. This strategy moves beyond simple demographic data and delves into real-time engagement patterns.

Implementing Website Tracking

To effectively utilize website activity segmentation, you need to implement robust tracking mechanisms. Google Analytics is a common starting point, but dedicated marketing automation platforms offer more sophisticated tracking and segmentation capabilities. Here’s how you can enhance your website tracking:

Google Analytics Event Tracking: Track specific user actions like button clicks, form submissions, video views, and file downloads.
Marketing Automation Platform Integration: Integrate your email marketing platform (e.g., Mailchimp, HubSpot, ActiveCampaign) with your website to track user behavior and automatically update subscriber profiles.
Custom JavaScript Tracking: Implement custom JavaScript code to track more complex user interactions and send data to your marketing automation platform.

Example 1: Tracking Product Page Views
Let’s say you sell clothing online. You can use Google Analytics event tracking to record each time a user views a specific product page.

// Example Google Analytics Event Tracking code
ga('send', 'event', 'Product Views', 'View', 'Product Name', 'Product ID');

This code snippet sends an event to Google Analytics whenever a user views a product page. The event category is “Product Views”, the action is “View”, and the label is the product name and ID. You can then create segments in your marketing automation platform based on these events. For example, you could create a segment of users who viewed a specific product category (e.g., “summer dresses”) and send them an email showcasing new arrivals or special offers in that category.

Example 2: Identifying Abandoned Carts
Tracking abandoned carts is crucial for e-commerce businesses. You can use a combination of website tracking and email automation to recover lost sales.

Track when a user adds an item to their cart.
Monitor if the user proceeds to checkout.
If the user doesn’t complete the purchase within a specific timeframe (e.g., 30 minutes), trigger an abandoned cart email.

//Example Javascript to detect abandonment
window.onbeforeunload = function(event) {
  //Check if items in cart and checkout not initiated
  if(cartNotEmpty() && !checkoutInitiated()){
    //Trigger event to backend to flag potential abandonment
    sendAbandonmentSignal();
  }
};

The `sendAbandonmentSignal()` function would then communicate with your backend to flag the user in your marketing automation system. The system would then trigger an email sequence. The email sequence could include a reminder of the items left in their cart, an offer of free shipping, or a discount to incentivize them to complete the purchase. A typical abandoned cart email might include: a visual of the cart contents, a direct link back to the checkout page, and a compelling reason to finalize the order.

Segmenting Based on Website Activity

Once you’ve implemented website tracking, you can start segmenting your email subscribers based on their behavior. Here are some common website activity segments:

Page Visitors: Segment users based on the specific pages they’ve visited (e.g., product pages, blog posts, pricing pages).
Content Downloaders: Identify users who have downloaded specific resources like e-books, white papers, or case studies.
Form Submitters: Segment users based on the forms they’ve submitted (e.g., contact form, registration form, lead generation form).
Event Attendees: Track users who have registered for or attended webinars, workshops, or other events.
Inactive Users: Identify users who haven’t visited your website in a specific timeframe (e.g., 30 days, 90 days).

New blog posts about SEO
Invitations to SEO webinars
Offers for SEO tools or services

This targeted approach is much more effective than sending them generic marketing emails.

Purchase Behavior Segmentation

Key Purchase Behavior Metrics

To effectively segment based on purchase behavior, you need to track and analyze key metrics. Here are some of the most important:

Recency: How recently did the customer make a purchase?
Frequency: How often does the customer make purchases?
Monetary Value: How much money has the customer spent in total?
Average Order Value: What is the average amount the customer spends per order?
Product Categories Purchased: What types of products does the customer typically buy?
Customer Lifetime Value (CLTV): A prediction of the net profit attributed to the entire future relationship with a customer.

These metrics can be combined to create more sophisticated segments. For example, you could segment customers based on their RFM (Recency, Frequency, Monetary Value) score.

Segmenting Based on Purchase History

Here are some examples of purchase behavior segments you can create:

High-Value Customers: Customers with high monetary value and frequent purchases.
Repeat Customers: Customers who have made multiple purchases.
First-Time Buyers: Customers who have made their first purchase.
Lapsed Customers: Customers who haven’t made a purchase in a specific timeframe.
Product-Specific Customers: Customers who have purchased a specific product or product category.

Example 1: Rewarding High-Value Customers
Identify your top 10% of customers based on their CLTV. Send them exclusive offers, early access to new products, or personalized thank-you notes.

// SQL example to identify high-value customers (simplified)
SELECT customer_id, SUM(order_total) AS total_spent
FROM orders
GROUP BY customer_id
ORDER BY total_spent DESC
LIMIT 0.1 * (SELECT COUNT(*) FROM customers); //Top 10 percent

//Example using python and pandas

import pandas as pd
from datetime import datetime, timedelta

#Assume dataframe 'orders' contains customer_id and order_date

cutoff_date = datetime.now() - timedelta(days=180) #6 months ago

lapsed_customers = orders.groupby('customer_id')['order_date'].max()
lapsed_customers = lapsed_customers[lapsed_customers < cutoff_date].index.tolist()
#lapsed_customers now contains a list of customer_ids

#Integrate with email marketing platform to segment and send campaign

The pandas code identifies those users whose last purchase was more than 6 months ago and allows you to feed that list to your email marketing platform to initiate a re-engagement campaign.
