BuddyPress.org

@jerrythemouse https://wordpress.org/plugins/mailpoet-paid-memberships-pro-add-on works fine with Mailpoet 3.

There is no specific limitation from Paid Membership Pro I have seen upto so far where it limits you to fetch registered user email and sync it to any 3rd party integration.

@jerrythemouse To add a membership layer, you can use Paid Membership Pro, which also comes with a BuddyPress addon.

Paid Memberships Pro – Content Restriction, User Registration, & Paid Subscriptions

BuddyPress & BuddyBoss Private Community with PMPro – Restrict Profiles, Groups, Messaging, Forum Discussions
