I wonder if this is true or not, personally I don't use email enough to invest in a product like this ATM but have been kicking the idea of starting a home based business up for a while now and think something like this would fit quite well. Saying Email is just fine or whatever is along the lines of the re-inventing the wheel argument yet every once in a while someone does exactly that and the world is a better place for it! *Edit* The one thing that makes me a bit nervous is signing up with my google account, I wish there was more information on the security behind doing this, in other words am I handing the keys to the kingdom over to a 3rd party by doing this? Is my google account subject to any vulnerabilities this app may or may not have? These questions make me reluctant to "Sign Up" especially for a trial.
