Thnaks for your feedback. Thinking about it, you were spot on. I wasnt sure it was a vitamin or a painkiller, hence i assumed it might be a painkiller for lot of people, where i was completely wrong. Thanks once again for your feedback.
You've likely learned a lot about gmail/imap/mail in general, see if you can leverage that instead of walking away completely. Do some brainstorming on how you can turn this into something that is closer to a painkiller, or has some kind of virality to get less expensive growth.

Your product is a vitamin, it's a nice thing to have, not a need to have. Personal email backup is not a pain point—It's a nice to have and it's much harder to sell vitamins than it is to sell painkillers.
