I bought 1 code to test Mailtag to see how it compares to other email tracking software we've used in the past. So far it's pretty good, and always improving. Ben has provided responsive support. This looks to be a great LTD solution to the mail tracking problem.

For us we don't want to use any of the free solutions out there due to the branding that it inserts on the email, and we wanted the tracking pixel to come from our custom domain (mycompany.com) which Mailtag supports.

From talking to Ben via Chat they'll have Team Management support coming out in 3 weeks (so Mid October?) which basically is a gamechanger. According to the messages he's sent this will be included to the AppSumo buyers as well.

I'm now max stacking this for all our employees.
