When you are testing templates:
- Same email sent repeatedly to same address does not work. It does not show up in Sent Email. Presumably this is your anti-spam. This complicates testing emails.
- Suggestion: Turn off the repeat email detection for user's domain - if I am sending an email repeatedly to someone at my domain this is almost certainly legitimate testing.
- Despite the email not going out, you still get the message that sending the email succeeded. This is just wrong - it did not succeed.
