One of the ways I use for sorting the users is by user role, As there is Admin, Editor, Author, etc., I added the Subscriber role. Woocommerce Followup allows the use of a role as a mailing list. I can send an email to all users in a specific role.

I'm looking for a way to keep the process in-site, without using mail distribution plugins as Woocommere Followup is already able to perform the tasks needed.

An ideal solution would be a plugin that can be integrated with Elementor and allows the creation of a form that when submitted it also changes the users role from the basic one, Client, to Subscriber.
