Migrating your old emails to your Gmail account is not that difficult nowadays! Gmail provides a simple feature to do the same.
If you are looking for how to do, this article will help you.
Before you begin you need to enable POP download, to do so, access your old account and go to Settings -> Forwarding and POP/IMAP. In the POP Download section choose to enable.
Step 1: Open your Gmail account
Step 2: Go to Settings > Accounts, then under “Check mail from other accounts (using POP3),” click “Add a POP3 mail account you own.”
Step 3: Enter the e-mail address of the account you want to migrate (your old e-mail address).
step 4: Enter the password for the e-mail account you’re migrating, as well as your e-mail provider’s POP server name and port number, if you run into any problems, check with your provider to get the correct details.
Step 5: Now you can decide the import settings as per your requirement.
* If you want to delete your old e-mail messages off of your old account provider's server after Gmail imports them, check the box. * We recommend using SSL to check for new messages. SSL is more secure and will help protect you when you're using Gmail in public Wi-Fi networks. * You can label incoming messages if you'd like. Using the default label of your old e-mail address might help you find older messages a little easier, but this is totally up to you. * Archiving incoming messages is probably a good idea so you don't fill up your Inbox with all your old e-mail.
Step 6: Click the Add Account button.
Step 7: You can check the import history by locating, Settings > Accounts, then under “Check mail from other accounts (using POP3),” click on “View history.”
Step 8: Once you’ve verified that the import is done, you can remove the account from Gmail.
