I’ve been using your plugin for a while and it is awesome!
At the moment I am trying to integrate the user registration but can not figure out how to get the first name in the registration form to become the first name in the newsletter as well.
Hi, the registration (default) of WordPress does not collect the first name. Have you a custom form?
Actually there is not a way to set a preference for users subscribed via registration (but you can send a newsletter only to subscribers connected to wordpress users – actually it should be an option in the composer).
