Hi guys.
We have an issue on a solution, where users are duplicated (maybe on user import). The issue is that when a user unsubscribes to the newsletters, it is only one of the users that unsibscribes newsletters. The users have the same email address but are in different groups. On of the groups (customers) is a group that we do not use, because of no ecommerce (there was on a earlier solution). So my question is:
How do we merge/delete and filter these users on email address and keep the email permissions on the users that has recieved and email from system lately?
