GMAIL, its fast, offers huge space, free POP3, free forwarding, great threading feature, great search, whatelse can you ask for in a free service.
I love yahoo because I can filter and forward important messages (you made a sale and similar) to my mobile.
MyWay for me... though i wanna have a gmail account but i haven't receive any invites to create or sign-up yet. If im not mistaken, you should first receive an invite from those people who has an account already so you could sign-up for an e-mail account. Am i right?
You can get a gmail invite easily now. you post your request and you will receive hundreds of invites
My primary email is handled through my ISP. Gmail is my favorite for business/hobby related messages. I still use yahoo when I need to sign up for misc things, that is where my spam ends up
Yahoo mail works fine for me, been using it for about 6 years. I would like to try out their new mail beta, the present interface is a bit old.
My website has a free webmail service (see signature), so I use that one the most (and I think it has more "character" than the others). However, I have used most of the others too: Gmail, Yahoo!, Hotmail, etc. Gmail is fine, but finicky. Sometimes service not available. I use this account for all e-newsletters, etc. That way, I can save them up and refer to them later without worrying about having to delete some to free up space. I don't like Hotmail. Half the time I try to log on I get a "Service Unavailable" error. Perhaps they are so busy, their servers are overloaded. Whatever the case may be, I have really lessened my activity with Hotmail. Yahoo! is good. Can't say I have ever been unable to access my account. They gave a good amount of storage, and a nice interface. The worst e-mail service I have encountered is any e-mail service powered by mail.com. Way too many ads. And too often I get a "Service Unavailable" error. I can't help but think they are using up too much of their bandwidth on ads and pop-ups instead of providing an e-mail service. Maybe if they cut down on the amount of ads, their servers wouldn't be overloaded so often. Netscape, Excite!, Myway, Eudora, Opera, etc. They all offer pretty good e-mail services. But unless you are particularly attached to any of their products, I don't see the draw.
