A very interesting product. Integration with Gmail seems to be working pretty well. I know I would use this, along with my friends / colleagues for both personal and business emails. It would be interesting to perhaps see a web app or mobile version where you could paste in the contents of an email or simply a browser plugin which checks all text entered into web pages, rather than just for emails. But I'm sure you've considered this and there are probably many reasons why you haven't (yet) gone down that route. I suspect a lot of work has gone into making this a genuinely useful product, so congratulations on achieving that.
