Configuring IMAP for Reply Tracking in Postigo

Postigo allows you to automatically collect replies to your email campaigns sent through connected SMTP accounts. To do this, you need to properly configure the IMAP connection for each account. IMAP (Internet Message Access Protocol) is a protocol that allows you to access email stored on a mail server.

Proper IMAP configuration ensures that Postigo regularly checks your mailbox and records replies, allowing you to respond promptly to interested leads and effectively manage your campaigns.

IMAP Fields in the Postigo SMTP Account Form

When adding or editing an SMTP account in Postigo, you will see the following fields required for IMAP configuration:

  • IMAP Server: The address of your email provider's IMAP server. This address indicates where Postigo should look for incoming messages.
  • IMAP Port: The port number used for the IMAP connection. Ports 993 (with SSL) or 143 (without SSL) are commonly used.
  • SSL (Secure Sockets Layer): Indicates whether to use SSL encryption for a secure connection to the IMAP server. It is always recommended to use SSL to protect your data.

Make sure you enter the exact data provided by your email provider. Incorrect IMAP parameters will prevent reply collection.

Standard IMAP Settings for Popular Email Providers

For your convenience, below are the standard IMAP settings for the most popular email providers. Note that these settings may change, so it is always recommended to check the latest information on your provider's website.

  • Gmail:
    • IMAP Server: imap.gmail.com
    • IMAP Port: 993
    • SSL: Enabled
  • Outlook (Office 365):
    • IMAP Server: outlook.office365.com
    • IMAP Port: 993
    • SSL: Enabled
  • Yandex:
    • IMAP Server: imap.yandex.ru
    • IMAP Port: 993
    • SSL: Enabled

Important: For Gmail, you may need to enable "Less secure app access" in your Google account security settings. However, this reduces the security of your account, so it is recommended to use two-factor authentication and generate an app password specifically for Postigo, if this option is available.

How Postigo Checks Email

Postigo automatically checks your mailbox for new replies every 5 minutes. This ensures timely detection of responses and allows you to quickly respond to interested leads. This interval cannot be changed.

Postigo uses IMAP IDLE (if supported by the server) to receive instant notifications of new messages. If IMAP IDLE is not supported, Postigo performs regular checks at the specified interval.

Problems and Solutions

If you have problems configuring IMAP, try the following solutions:

  • Check the accuracy of the entered data: Make sure you have correctly specified the IMAP server address, port, and SSL parameters.
  • Check the email provider's settings: Make sure IMAP is enabled in your email account settings.
  • Check the firewall: Make sure your firewall is not blocking the connection to the IMAP server.
  • Use an app password: If your email provider supports app passwords, use it instead of your main account password. This increases security.
  • Contact support: If you cannot solve the problem yourself, contact Postigo support for assistance.
