After you insert new user with
wp_insert_user()
, you can call thiswp_new_user_notification()
function to send mail for newly registered users.However, In order to customise them, you need to define this function and save it as a plugin of its own. But, it still have a chance that some other plugin (that is called before this) have control over it. So, the best way of customising it is saving it as a mu-plugin. Just create a folder ‘mu-plugins’ under wp-content and save it under a php filename.
