It works

Its simple and its a GUI. Yes everyone knows that OSX comes with postfix or similar tool, but when Im having to learn yet another library / framework / language; Id rather keep stuff like this basic and brainless. (Besides Im not going to run my own SMTP server in production anyways.) It does what it advertises.

I think the developer dropped the price in half but Im sure its still too pricey for most people, hence the lack of 5 stars. For me, its worth the money for the convenience and time it saves.
