If you’re using Gmail as your main mail client, you may want a way to import your mail or other information, such as contacts.
To import some email into Gmail, head to the Settings screen, then to the “Accounts and Import” tab.
There, you should see the option to “Import Mail and Contacts”. You can import details from Yahoo, Hotmail, AOL and POP3 accounts, along with webmail accounts as well.
Just follow the prompts, and you should be able to import your mail fairly quickly.
