For your own security, our systems will not allow us to manually change the email address associated to an account nor allow you the user to do so. The signup process ensures that the original email address is always the primary username.
If you want to use Trint under a new email, you’ll need to register for a new account with the new email address you’d like to use and sign up for a new plan. Sorry that sounds like a hassle, but security comes first here at Trint. 🔐
