Thank you for contacting us.
Login Customizer doesn’t send any mail to new user/s.
WordPress by default sends the new user an email containing the password reset email, in this email the user can set its password for the very first time.
This is the default behavior of WordPress.
If you want to you implement the removal of this email for the subscriber role do let me know.
But I got one from “email@example.com” with the content:
Almost there! Thanks for activating Login Customizer. We are super-excited to have you on board. Before you get started, please verify your email address below (promise not to send you any spam).
I think that’s not from WordPress…
Just wanted to be sure to you, subscribers users will not get this email at all. This will be only be received by the website Admin only once.
so no worries, best of luck to your learning platform.
