Which is the best Email Service Provider?

It really depends on what you are trying to achieve online. I like gmail overall. It is a fairly big box. Free and can be drawn in through various SMTP services. Yahoo was a good box but to get all of gmail services you would now have to pay for them. So that slips in my opinion. I don't want to pay for things that I use to get free. Hotmail is such a small box I only use it for spam.

i think mail.com is the best

What I think is Gmail.

My preference is for yahooo mail.
