I was confused by the two confirm new email templates too. But they are slightly different. One is sent when an admin adds a new email address to a user’s profile, and the other one is sent when they do it themselves. The last line is different.
Confirm your new email address for %{site_name} by clicking on the following link:
%{base_url}/u/confirm-new-email/%{email_token}
If you did not request this change, please contact a [site admin](%{base_url}/about).
Confirm your new email address for %{site_name} by clicking on the following link:
%{base_url}/u/confirm-new-email/%{email_token}
This email change was requested by a site admin. If you did not request this change, please contact a [site admin](%{base_url}/about).
I think deleting one would break one of the emails sent.
My templates also both use the same link. Maybe yours differ because you had customized the template before.
I wonder why parts of the link are customizable by the template. If the template only used %{confirmation_link}, from my understanding, the link wouldn’t become outdated even if the template was customized.
