There are so many benefits to encourage you to set up email address using Google’s free email service Gmail, but you might be reluctant to do so because you have a significant amount of old emails stored with your old email address or you don’t want to change you email address.
Gmail has the functionality that allows you to import your old email to your newly set up email address.
If you wish to keep the old email address that is not a problem either! You can use Mail Fetcher in Gmail to regularly check your other account for new mail and then have it all received in the one Gmail inbox.
This allows you to have the excellent benefits of the Google free email system, but still hold onto a well established and known email address.
