Is it possible to have test emails automatically labeled as tests in the subject? Every time I forget to tell people a test email is coming, they freak out thinking it went out without them reviewing. I know I need to get better at remembering to tell people a test is coming, but I've worked with other email providers that automatically add this label, and it'd be a really nice feature. So the subject would just look like – SUBJECT: [Test] Here is the subject of the email!
