Which online email client to use?

Question

Email

Previously used The BAT, there are other analogues.
But would you like something similar online? Those. all the boxes in one place so that you can enter from anywhere.
Gmail has a limit of only 5 mailboxes.
In Yandex, I don’t quite like the interface, and as far as I understand, you can only receive letters from other mailboxes, but not send them.
