I thought I’d just least this here:
Nylas N1 (https://nylas.com/) is an opensource mail suite (server / client) designed for sales people.
It integrates with Salesforces in a very nice way. Obviously the first thing that came to my mind was “hey could we do that with SuiteCRM” - and saw there isn’t even the slight reference to this on the internet.
So I am basically going to leave this here for now, more as a general information about some potentially cool information.
If anyone makes the plugin, please update us
