Tracking opens

On this page:

The package can track when and how many times a subscriber opens an automation mail.

Enabling open tracking

To use this feature, you must set track_opens to true of an automation mail you’re going to send. You can find an example of how to do this in the section on how to create an automation mail.

How it works under the hood

When you send an automation mail that has open tracking enabled, the email service provider will add a web beacon to it.. A web beacon is an extra img tag in the HTML of your mail. Its src attribute points to an unique endpoint on the domain of the email service provider.

Each time an email client tries to display the web beacon it will send a get request to email server. This way the email service provider will know the mail has been opened.

Via a web hook, the email service provider will let Mailcoach know that the mail has been opened.
