Communication is hard. People mostly get bad vibes from e-mail. Combine these to and your get a lot of unnecessary misunderstandings. I think the world needs more emotional intelligence and that requires healthy feedback.
https://xn--du8hsrobxe.ws is a simple tool to get feedback from people you communicate with.
1. You get a simple HTML code you can paste into your e-mail signature.
2. The code contains one question ("How did my e-mail make you feel?") and seven emoji.
3. People can click emoji to give you feedback.
4. You can see results for last 30 days.
I made this MVP during last weekend. I coded it only using left hand... right one was busy holding my baby daughter.
I'd be grateful for feedback. Thank you!
PS. Actually the URL is all emoji and .ws - too bad you can't post emoji in HN comments :(
