There seem to be a few different problems being solved by the suggestions in the comments:

1. I don't want to send out emails in dev mode. At all. (mailsafe) 2. I want an easier way of looking at the emails my server does send out (letter_opener, mailcatcher, mails_viewer) 3. I want to be able to preview an email without having to do the action that triggers it (mail_view)

mails_viewer can do 1 and 2. The default usage will not send out emails at all. But if you want, you can. So it's preview and conditional send.

mail_view requires you to write additional code. The pro is that you can preview it lively without doing the action again. The con is that you have to write the scenario for preview.
