Tracking pixel

A tracking pixel is a 1:1 pixel graphic generated by a line of code in an email. It tracks user behaviors and delivers personalized marketing to users as they browse the internet. Brands embed tracking pixels in either email headers or footers. Unlike cookies, which are highly noticeable and can be disabled, tracking pixels are virtually invisible to email subscribers.

An email pixel tracks the following:

  • The device used to open an email.

  • The number of people opening the email.

  • The count of people who clicked on any email links.

  • Duration of the email opened.

  • Where and when the users opened the email.
