Free Online Tool to Aggregate Email Accounts

I have a couple of yahoo and gmail accounts & I would like to access them all from one place. There are programs that allow this for things like IM/Skype and Facebook/myspace/twitter…but is there one for email accounts?

May I ask why you don’t just use something like outlook or if on mac, the built-in mail client?


nevermind, I see the keyword there is “online.”
