Multisite – Change Add user to Blog notification email
When adding an existing user to a blog (in the admin panel), a very basic email is sent. I am trying to overide this email so it is a bit more attractive – to at least have a clickable link.
Looking in user-new.php, it doesn’t appear to have an apply_filter.
How can I change this email without an apply_filter
The email is
You've been invited to join '%1$s' at. %2$s with the role of %3$s. Please click the following link to confirm the invite: %4$s'
