How to transfer emails from one Gmail account to another

Now that you have a G Cloud account from UC San Diego, you may want to import mail from an old personal Gmail account that you have been using for UC San Diego email. This guide will take you through the steps of moving all of your mail from the old account into the new account so that you have everything in one place. Note that this is for migrating mail only. This will not migrate any docs or sheets that you have saved in your personal Google account. Search Google for how to migrate Google Drive items and Google Docs/Sheets from one account to another.

Allow POP mail access on your old Gmail account

First, we need to set up POP (Post Office Protocol) mail access so your new Gmail account can import your mail.

  1. Log into your old Gmail account.
  2. Enable "Less secure app access" for your account. You might also need to turn off your security code or distorted text.
  3. Back in Gmail, click on the gear icon.
  4. Select ‘Settings’.
  5. Go to the ‘Forwarding and POP/IMAP’ tab.
  6. Under ‘POP Download’, select ‘Enable POP for all mail’.
  7. Go to the second part of the same section, which reads: “When messages are accessed with POP”.
  8. Hit the drop down menu and select what you want to happen to the emails in the old Gmail. Since you are moving mail from one account to the other, you should choose to delete the messages.
  9. Click on ‘Save changes’.
  10. Sign out of the old Gmail account.

Fetch emails with the new Gmail account

Now you need to go to your new Gmail account and tell it to bring all the old email from your other Gmail account.

  1. Log into your new Gmail account.
  2. Hit the gear icon.
  3. Select ‘Settings’.
  4. Go to the ‘Accounts and import’ tab.
  5. Go to the ‘Check mail from other accounts’ section.
  6. Select ‘Add a mail account’.
  7. Enter your old Gmail account and hit ‘Next’.
  8. Select ‘Import emails from my other account (POP3)’ and hit ‘Next’.
  9. Check the username is correct and enter the password for the old Gmail account.
  10. Under ‘POP Server’, select pop.gmail.com.
  11. Select port 995.
  12. Uncheck ‘Leave a copy of retrieved messages on the server’.
  13. Check ‘Always use a secure connection (SSL) when retrieving mail’.
  14. Click on ‘Add account’.
  15. Leave ‘Would you also like to be able to send mail as _____@gmail.com?’ unchecked.

Your new Gmail account will retrieve all messages from your old Gmail account. This may take a while if you have thousands of messages, so be patient.


Forward mail from the old Gmail account to the new Gmail account

After the mail import process is complete, there will be no more mail in your old account. However, you may still receive mail to that old account, so these steps will make sure those messages get forwarded to your new account.

  1. Log into your new Gmail account.
  2. Hit the gear icon.
  3. Select ‘Settings’.
  4. Go to the ‘Forwarding and POP/IMAP’ tab.
  5. Type in your new Gmail address.
  6. After confirming the email address is yours, choose to delete the messages when they are forwarded.
  7. Select ‘OK’.
  8. Click ‘Save Changes’ button at the bottom of the page, and you are done.

Stop pulling mail from the old Gmail account

Now that all your mail is in one location and incoming mail to the old account is being properly forwarded to the new account, you can remove the old POP account from your new Gmail account.

  1. Log into your new Gmail account.
  2. Hit the gear icon.
  3. Select ‘Settings’.
  4. Go to the ‘Accounts and import’ tab.
  5. Go to ‘Check mail from other accounts’.
  6. Hit the delete button next to your old Gmail account.
  7. Select ‘OK’ and you are done.

Now that you know the ins and outs of migrating email from one Gmail account to the other, you can rest assured you will never lose your precious electronic mail again.
