I run several different websites and its becoming a nuisance having to login to all the different ones checking emails, sometimes several times a day. Now I know I can add the emails to the email client found in Mac, but it just puts all the mails in the same inbox. I would like a program that can separate them, like tabs for browsers do. So I can quickly switch between the different emails without having to see all of the emails in one place. Any programs that can do this?
