Save Email Drafts Automatically
I would like suggest an auto save feature for email blasts. There have been times our admins have lost their hard work because they did not take the time to save it first themselves or they got logged out. Thank you for your consideration.
Released in 4.4
Sorry for a late reply.
This is a very good request and I'm surprised that there is no comments here. We have this in our queue but there no timeline yet for this - not in 2011 for sure.
