You can change the email address your Tryst account is linked to from the Dashboard. This address is the one your account is tied to and is used for logging into Tryst.
If you only want to change the address in the contact section on your profile, you can do that in the Edit Profile section.
Log in to your Tryst account and go to the Dashboard.
Select Change email under Account section.
Enter your new email address in the Email field and your current password in the Current password field. You won't be able to change your email address without your password.
You will receive an email to your new account with a confirmation button. Click this link to complete the email change.
Remember you will need to use this new address when signing into Tryst in future.
