If you'd like to track email opens, clicks, and other engagement metrics, you'll need to create a tracking link. Tracking links are special URLs that include email-tracking parameters. There are a few different ways to create tracking links. You can use a tool like Google Analytics, or a third-party email tracking service. Once you have your tracking link, you'll need to add it to your email's HTML code. This can be done by editing the email's code directly, or by using a tool like Campaign Monitor's link builder. Once your tracking link is in place, you'll be able to see detailed stats on who opened your email, what links they clicked, and more.
