Which email UsersWP sends a new user depends on the registration form’s Registration Action, and each email can be switched off on its own. Start by finding out which one should be going out.
Check which email applies
- Go to UsersWP > User Types and edit the registration form. Note the Registration Action.
- With Auto Approve or Auto Approve + Auto Login, UsersWP sends the Registration success email.
- With Require Email Activation, UsersWP sends the Registration activate email with the activation link instead.
Check the email settings
- Go to UsersWP > Emails > User Emails.
- Make sure Enable email is ticked for the email from the step above.
- Click Show Advanced and check the Subject and Body. An empty Body is fine, because UsersWP then sends its default text.
The admin copy is a separate email, New account registration on UsersWP > Emails > Admin Emails. An admin email with no user details usually means its body was edited and lost the [#extras#] tag, which holds the new user’s name, username and email.
Check the registration form
If the registration itself fails or behaves oddly, check the register form in UsersWP > Form Builder. Required fields such as Email must be active, and a field marked required but switched off can stop the form from completing. See Why can my users not register? for more checks.
Check delivery
If password reset and other site emails arrive but the registration email does not, the problem is in the steps above. If no site emails arrive, it is a delivery problem: set up an SMTP plugin and use an email log plugin to see whether WordPress sent the message and what the mail server replied.
