Just about everybody these days has more than one email account, usually more than can be counted on one hand. Personally, I have 5+ accounts with different email , including Yahoo, Gmail, Cox, my office email address, my website email, etc, etc. Currently, I use Outlook to check all of my accounts from one client application since it makes it easier to manage.
If you’re ok with Outlook, then there’s not a problem. However, if you prefer to use Gmail for everything since it’s web-based and therefore not tied down to one computer like Outlook, then you might be interested in knowing how to setup all of your email accounts in Gmail so you can receive all emails via your Google Inbox.
