Description

The UserPro Mailster connects UserPro registrations to Mailster lists, adding an opt-in checkbox to the registration form and automatically syncing new members as newsletter subscribers. The extension also lets each user manage their own subscription preferences directly through the UserPro profile, maintaining consistent segmentation between the members area and the email sends made by Mailster.
