Hi Jul.
That’s not something s2Member adds… It’s a nice idea, though! I’m making a note.
What you can do is send users a password instead of letting them pick one on registration. WP Admin > s2Member > General > Registration/Profile Fields & Options > Custom Password
That way they have to use the link they get by email to set the password.
Then in the users list, you can see from the logins counter who never logged into his account yet, and those who logged in obviously got their email and could open it.
Also possible, although a bit more advanced, would be to have in the Login Welcome Page, a bit of PHP that gives them a capability (e.g. verif_email) or changes their role (e.g. s2Member Level 1). https://s2member.com/kb-article/rolescapabilities-via-php/
I hope that helps. ??
