@burnout426 said in Opera Mail is still great. Continue development would be gorgeous:

Some testers have said there are no plans to provide a standalone M3. It will be part of Vivaldi like M2 is part of Opera 12.

Yes, I read about this aspect. It would not be a problem for me. If the Mail Client in it is as great as M2, then I am happy also with an Browser aside. 🙂
