M3 is on the way. There is still work to be done before it is ready to be shared, but we get closer each day.
Clearly we are eager to get it out to you, but not before we have fixed a few more bugs and added a bit more functionality.
It is getting closer...

Yes, a number of us have been using M3 for quite a while now. A lot of things are in place and are working fine.
Other things are missing and some things are a little unstable. We are working in particular on the stability side and adding a few more crucial items.
In the meantime we continue to polish and add features. There will still be loose ends feature wise when we release M3, but we are in a much better shape than ever before.
Personally I would not switch out M3 for any other mailer, including M2.

Thanks. IMHO it will be worth it. There is a reason why we are building it as there is nothing quite like it out there.
The focus is productivity, just like with Vivaldi in general. Helping you be more effective in the way you prefer to work and play.
