Very promising
Unusally generous free plan, which caught my attention first.
Still a pretty new service, so not fully battle tested yet, but it looks very promising so far.
Clean UI, good features, open source, and the team has been quick to fix bugs, it seems.
I would say the most promising new privacy and security focused mail services ive tried.
