Tracking email opens is enabled by default when you create a new campaign. This feature is available to Hunter users on all plans.
How Hunter tracks email open rates
When "track email opens" is enabled for a campaign, a unique tracking pixel is added to every email within that campaign. When the recipient opens the email, Hunter automatically logs an open event, letting you know when and how many times each recipient opened the email.
How to enable/disable the tracking
When launching a new campaign, you can disable or enable tracking opens and link clicks at the bottom of the content editor.
