Gmail users now can solely concentrate on using one email account instead of switching back and forth to other email accounts such as Yahoo!, Hotmail, or AOL. Now you can migrate all your emails and contacts easily via the new import feature.

After the migration, you can have new mail from those accounts forwarded to Gmail for the next 30 days. This allows you to have time to let everyone know what your new address is. Besides that, you can also label all of the imported mail, so you know which mail is coming from which account.

As per Gmail’s Blog:

Gmail now migrates email and contacts from other email providers, including Yahoo!, Hotmail, AOL, and many more. It’s much easier to make the transition now that you can bring along all your old email and contacts. You can even have your messages forwarded from your old account for 30 days, giving you time to take Gmail for a test drive while you make up your mind.

This new feature is available in all newly-created Gmail accounts, and it is slowly being rolled out to all existing accounts. It’ll take longer than the few hours or days that most Gmail features take to get out to everyone. You’ll know it’s on for your account when you see the Accounts and Import tab (formerly just called Accounts) under Settings. Sorry, businesses and schools using Google Apps won’t see these new migration options.

With that, there is no more reason not to use Gmail. Right?.
