I have been waiting a very long time for this type of tool to appear on Appsumo. I was going to use Amazon SES, but fortunately I don't have to anymore! :)
Setting up Emailit is fabulously easy. Admittedly, I encountered some problems along the way (my mistake), but support solved them very quickly.
The contact with George is amazing. It is rare to see such quality support!
The application dashboard is clear and very easy to use. The development of the tool also promises to be impressive.
I just really hope that Emailit will not die anytime soon, as it happens with apps from Appsumo.
I wish you much success, George! Needless to say, I highly recommend this tool!
