For free mail, there is gmail exists.
For professional paid mail, there are fastmail and gsuite exist.
Both two are the best excellent above any other.

I am afraid some years later, the other providers will have to shutdown, including but not only yahoo, outlook, gmx, aol.
For example, in Russia, the big players QIP.ru and e1.ru, have moved their email hosting to yandex (Russian's google). They don't want to develop their own email service any more.

How do you think so?
