How to import old mail into Gmail on Windows 10 PC?

1. Use Import mail and contacts feature

  1. Open Gmail and log in to your new account.
  2. Click the Gear icon in the top right corner and choose Settings.
  3. Go to Accounts and Import tab.
  4. Click on Import mail and contacts link.
  5. Now sign in to your old email account by following the instructions on the screen.
  6. If you did everything properly, you’ll see Start import option.

Gmail comes with a feature that allows you to import old emails from different email providers just with a couple of clicks.

By doing so old emails from your old account will be forwarded to your new Gmail account automatically and you’ll be able to access them in Gmail. Keep in mind that you should inform all your contacts that you won’t be using the old email address anymore.

2. Import all old emails and forward all new emails to your Gmail account

  1. Open your old Gmail account.
  2. Click the Gear icon and choose Settings.
  3. Navigate to Forwarding and POP/IMAP tab.
  4. In POP Download section select Enable POP for all mail.
  5. Set When messages are accessed with POP to keep Gmail’s copy in the inbox.
  6. Click Save Changes.

If you create a new Gmail account and you want to receive email messages that are sent to your old email account, you need to change a few settings.

This method works for both Gmail and third-party email accounts, but keep in mind that some email providers might not support this feature.

After changing these settings on your old Gmail account, you need to configure your new Gmail account. To do that, follow these steps:

  1. Log in to your new Gmail account.
  2. Click the Gear icon in the top right corner and choose Settings from the menu.
  3. In Check mail from other accounts section click on Add a mail account you own.
  4. Enter the address of the old Gmail account and click Next.
  5. Optional: If you use Gmail with your work or school account you might have to change POP Server to and select Port 110.
  6. Optional: You have several options available that you can use.
  7. The first option is Leave a copy of retrieved message on the server.
    • You can keep this option unchecked because this setting is controlled by your other account.
    • Next option is Always use a secure connection (SSL) when retrieving email.
    • This option will encrypt your connection thus making your email messages safe from malicious users.
    • Label incoming messages feature is designed to help you distinguish messages received on your old account.
    • Lastly, Archive incoming messages option will move all email messages received on your old account to the archive.
    • By enabling this option you won’t see any emails from your old account in your Inbox, so we recommend to turn this feature off.
  8. After you’re done, click Add Account button and your old account should be now connected with your new account.
  9. After adding your old account, you’ll get a message asking you whether you want to use your old email address or the new one to respond to emails from your old account.

As we already mentioned, this feature also works with third-party email providers, but in order to use it you need to enable POP on your old email account. After doing that, try to add your old email account by using the steps above.

If you’re not able to add it, you might want to contact your old email provider and ask them if POP is supported on your account.

If you want, you can stop receiving new emails from your old account by changing few settings. To do that, follow these steps:

  1. Open your new Gmail account.
  2. Click the Gear icon in the top right corner and choose Settings.
  3. Navigate to Accounts and Imports tab.
  4. In the Check mail from other accounts section locate your old email account and click Delete next to it.

Keep in mind that deleting your old email account will only prevent new emails from being forwarded to your new account. Any old emails that you received will remain on your account.

As you can see, this method is a bit complicated, but it allows you to use your old email account alongside your new Gmail account without any problems.

This is extremely useful if you want to keep using your old email account or if you didn’t notify all your contacts about the change of your email address.

One flaw of this method is that it doesn’t allow you to import contacts from your old email account, but you can easily import contacts manually to Gmail. If you want to import contacts from non-Gmail account, you need to do the following:

  1. Open Google Contacts.
  2. In the menu on the left click More and choose Import.
  3. Select the desired method.
  4. Log in to your old email and click Agree.
  5. After the contacts are imported, click OK.

To import contacts from another Gmail account, you need to first export your contacts as a CSV file. To do that, follow these steps:

  1. Make sure that you’re signed in to your old Gmail account.
  2. Open old Google Contacts and choose More > Export.
  3. Select All contacts and choose Google CSV format.
  4. Select the save location for the .csv file and save it on your PC.
  5. Log out of your old Gmail account.

Now you need to import those contacts to your new Gmail account. To do that follow these steps:

  1. Log in to your new Gmail account and open old Google Contacts.
  2. Choose More > Import.
  3. Now click on Choose File button and locate the .csv file that you created.
  4. Select the file and click the Import button.

3. Import old emails from desktop client

If you use a desktop email client, such as Thunderbird, for your emails, you should know that all your emails are saved locally on your PC. If your email provider doesn’t offer webmail service, you can still import your emails from your desktop client.

To do that, you need to enable IMAP for your Gmail account and add Gmail to your email client. After doing that, simply select the emails that you want in your old email account and drag them to Gmail’s Inbox folder in your email client.

Keep in mind that this process can take a while depending on the number of email messages, so you’ll have to be patient.

One of the biggest problems, when you’re switching to a new email account, are your emails, but as you can see, you can easily import old emails into Gmail by using any of our solutions.
