What is the difference in @AOL.com and @AIM.com?

Short answer: They are mostly the same. And you can use any service and product with any name.

Longer answer: @aol.com have been used before for our ISP/Access customers, whereas the @aim.com was used for our free users. Now all products AOL is offering are free (except access) and it doesn't really matter anymore.

If you have an @aim.com address you can in fact also receive mail under @aol.com - and vice versa.

In addition you don't even have to use @aim.com or @aol.com at all (since those domains are really crowded and it's hard to get a cool name). You can sign up for other (free) domains at http://www.tunome.com - and can use that email address to access all AOL and AIM products for free as well.

I would actually suggest you either get an @aim.com or a Tunome address, since those account types will get a true internet/inbox mailbox. Which means mail stored there never expires and you can truly enjoy the unlimited storage we are offering for all our users.

Just to add onto the answer for anyone who might wonder whether Tunome,com is a third-party service - its not. Tunome is an AOL service which is why its so well integrated with their services.

there really isnt a difference when it comes to ur mailbox aim just allows u to talk to ur friend in real time
