If you are fed up with the slow loading yahoo mail account and looking to transfer all your previously saved emails in your yahoo account to your new google gmail account. For this you need to first visit the account settings page where you will find a option – Import mail and contacts : Import from Yahoo!, Hotmail, AOL, or other webmail or POP3 accounts.

Step 1 : Next once you click on the option to Import, you will get a new window with a option to enter your other email address which you want to import.

Next you will be asked to enter the password of that specific email account to authenticate yourself.

Step 2 : The trueswitch technology would ask you to select a few options for the import.
Import contacts
Import mail
Import new mail for next 30 days
Add label to all imported mail

Once you enter these all your emails will be transferred. Thats it after this step all your emails would be imported with the following message. Your messages and contacts are being imported. It may take several hours (sometimes up to 2 days) before you start to see imported messages.
