Hi :-)
I think it would be lovely to have the option to receive notifications via webhook instead of an email.
My main goal is to be able to react to notifications more easily and without having to tinker with the crude tools my mail provider offers.
For atlassian, i think, this should also be interesting as calling a webhook is a lot less costly than sending an email.
For all life on the planet this should also be relevant because the lower costs will likely correlate with lower carbon emissions.
There is one other questions that might also be adressed with this option:
