I've never had a problem with any e-mails I've had. I use a gmail account for school, because of GoogleDocs, and I use AOL/AIM for my personal stuff. The occasional spam, but that's usual. =p
i use yahoo to check my mail on any notifications i get from social websites n blah i use gmail for youtube and i also used it to talk to my gf while i had to attend school until they blocked it -.- i use msn for windlows live messanger so i can talk to all my online friends so i use alot of emails so i cant really pick a best
I have hotmail only because when i was 7, we ran out of optimum online accounts so my dad picked this one for me. I hate it but don't feel like switching.
