Sent broadcast edited and saved becomes a draft only
We always edit unsent broadcasts from the draft tab and schedule them from there as well. Recently, we set up a message and changed the setting so that the message would go out the next morning. We then sent a test message. It appears that the test message that was sent may have then been edited from the Sent tab and scheduled for broadcast. The message went out immediately instead of the next day, as it was thought to have been scheduled.
As a safeguard, I believe that if someone edits a "sent" message and saves it, the message should be created as a new draft in the draft tab. The message would only be able to be scheduled from the draft tab. This would alert the user to the fact that there were now two drafts.
In our case, that would have eliminated the issue of a second message going out to our lists the same day and the risk of alienating our subscribers.
Thanks for your consideration.
