sounds so small but we're so upset to lose read receipts.
We're leaving missive. It was the perfect email client for us until now. Hopefully you'll reconsider and bring it back.
I showed it to a friend that runs his own company a few weeks ago and he fell in love. We spoke today about the removal of read receipts and he said "why would they do that, thats one of the number 1 reasons we were considering it".
I assume its a very small chance that it will ever come back. Good luck. Hope to be back again.
