I have no idea how to achieve this, but I'd like to add custom SMTP tags to the mails sent by Devise, so that I can better segment mailings (for example, new user mailings).
Ideally if there's a simple way to do this—I'd rather not have to re-write Devise's mailers entirely if I don't have to, but I can't seem to find an easy way of adding these tags.
