What is a good reliable web-based email client?

My account at mail.com is down again. Haven't had these issues in a few years.
But it's been 24 hours. A couple years back they changed available addresses and I lost
one account there. Never recovered anything from it, it was so quick.

It is a major pain to migrate my personal business account to another place. And even
then how do you re-archive account contents. Can't be done to preserve the original email
headers I think.

Fortunately I use separate accounts for other things, but most of those are not
used at all so I have no idea if they're reliable.

Is gmail any good?

Yahoo mail now offers the capability to integrate all Yahoo mail accounts into one.
Boy that would be confusing. And I don't want personal business with my family account.

Can you integrate just two Yahoo accounts?

So I'm seeking a free non-Yahoo email provider that is reliable.

I'd be interested to hear others' solutions to their voluminous email.


Thanks all!
