The Manage Subscription Page
MailPoet provides a default page for subscribers to manage their subscription. When they access the Manage Your Subscription link in a Newsletter, they go to a page like this:
In this page, your subscribers are able to edit their subscription information (including custom fields, if you have imported subscribers with CSV files), except change the email address. For that, they will need to unsubscribe and sign up again.
They can also edit their status (Subscribe / Unsubscribed), which is important if they accidentally got themselves unsubscribed by clicking on the Unsubscribe link in a Newsletter.
And they can manage the Newsletter lists they are in.
You can edit the page settings by going to MailPoet > Settings > Basics:
