If you're using a transactional messaging provider that doesn't handle unsubscribes properly, or if you are using several messaging providers, you can create an unsubscribe link in Fresh Relevance and use it in your email templates.
Create an unsubscribe link
Expand the User menu, and go to Settings > Triggers and Messaging integrations.
Select Unsubscribe Link.
For the Redirect URL, enter the URL of the webpage you want your customers to see when they unsubscribe.
To include the email address in the URL, use
%e. For example,https://www.example.com/?email=%e.Select GO. This generates a handler URL.
Copy and paste the handler URL into the template used in your email marketing system.
Replace the [email] part of the URL with a suitable mailmerge in your email marketing system. For example, for Dotdigital, use @EMAIL@.
Your unsubscribe link is now ready to be used in your email templates.
