The only thing that attract my eyeball is the tabs. Others are identical to all sorts of mail agent product out there. Also, you need to think about who is your customer. If you are targeting at developers, the front-end isn't that important but the performance and functionality are crucial. For what you currently offer, I don't see a clear position of your product.

Thank you for your feedback. The target market is not really developers but people who use email more than 3 hours per date. It has a lot of similar functionality to for example Outlook - but there are small things - for example adding an email to your calendar by clicking on a date that Outlook doesn't have but makes a big difference in how you use it I think. Glad to receive your feedback I will try to clarify my positioning also!
