Can you imlement an option for sending out a testmail after setup mails? I noticed when I did a test signup that an imported clickable image to like my Facebook page, that the image didn't resized and was not clickable.
In the setup it looks okay, so I only could discover this with doing a test signup and wait till the mails in sequence/time arrive. And then see if everything works fine. As simple button with "Send testmail" next to every mail would solve this, woud be great.
