Don't let your overflowing inbox hold you hostage. If you've been hoarding thousands of messages in your Gmail account, it's only natural to balk at spending a day or two sifting through clutter. Fortunately, there's an easy solution—but you'll want to take advantage of it quickly, because Google is planning to end support for POP3 (Post Office Protocol 3) this year.

Currently, Gmail users can use POP3 to automatically fetch emails from one account and import them into another. This feature has long been a workaround for those running out of the free 15GB of storage that Google allocates across Gmail, Google Drive, and Google Photos. However, new users lost access to POP3 in the first quarter of 2026, and existing users will lose it later this year. Once POP3 is gone, transferring large volumes of emails will become significantly harder, requiring third-party tools or manual downloads.

Why You Should Act Now

The 15GB free storage might seem generous when you first create a Gmail account, but it fills up quickly. Photos from Google Photos, files saved in Drive, and email attachments all count against that quota. Once you hit the limit, you can no longer send or receive new emails, which can be disruptive for work and personal communication.

Google offers a paid solution: Google One plans start at 100GB for $20 per year. While that's not expensive, paying for storage to keep old emails you may never need feels unnecessary. The alternative is manual deletion—sifting through years of correspondence to decide what to keep. That process is tedious and time-consuming, especially if you have tens of thousands of messages.

The nuclear option is to transfer all your old emails to a new, dedicated archive account. This frees up your primary inbox, gives you a fresh start, and costs nothing. But because Google is retiring POP3, you need to act soon.

Understanding POP3 and Its Role

POP3 is a standard email protocol used to download messages from a server to a local client. In Gmail, it has been repurposed to allow one account to pull emails from another. When you enable POP3 on your primary account and set up your archive account to fetch mail via POP3, the transfer happens automatically in the background. Google is ending support for this feature to encourage users to adopt more modern protocols like IMAP, but IMAP does not allow bulk transfer from one account to another without manual intervention.

Once POP3 is disabled, the only way to move large volumes of email will be through Google Takeout (which provides a download) and then re-uploading to the new account, a process that can be slow and requires storage on your computer. Therefore, the time to act is now.

Step-by-Step Guide to Transferring Gmail Messages

Back Up Your Emails First

Before starting the transfer, it's wise to create a backup. Use Google Takeout to download all your Gmail data. This can take hours depending on your mailbox size—for example, a test account with 75,000 messages completed the download in about two hours. Store the backup on your computer or an external drive. You can delete it later if you wish, but having a local copy adds insurance against data loss.

Enable POP3 on Your Primary Account

1. Log into your primary Gmail account.
2. Click the gear icon at the top right and select "See all settings."
3. Go to the "Forwarding and POP/IMAP" tab.
4. Choose "Enable POP for all mail."
5. Under "When messages are accessed with POP," select "delete Gmail's copy" to automatically remove emails from the primary account after transfer.
6. Click "Save Changes."

Create a New Archive Account

If you don't already have a second Gmail account, create one. This will be your archive where all old emails will live. You can set a label to organize them.

Set Up POP3 Import on the Archive Account

1. Log into your new archive account.
2. Click the gear icon and go to "See all settings."
3. Select the "Accounts and Import" tab.
4. Next to "Check mail from other accounts," click "Add a mail account."
5. Enter your primary Gmail address and click "Next."
6. Choose "Import emails from my other account (POP3)" and click "Next" again.
7. Enter the password for your primary account. (Note: You may need to generate an app password—see below.)
8. Set the port to 995.
9. Check these three boxes: "Always use a secure connection (SSL) when retrieving mail," "Label incoming messages," and "Archive incoming messages (Skip the Inbox)."
10. Click "Add Account."
11. Optionally, choose whether to also be able to send mail as the primary address.

Creating a Google App Password

In many cases, Gmail's regular password will not work for POP3 fetching. You need a 16-digit app password. To generate one:

1. Go to https://myaccount.google.com/apppasswords. (You must have 2-Step Verification enabled on your Google account.)
2. Create a name for the password, like "Gmail Transfer."
3. Click "Create" and copy the generated password. It will appear only once.
4. Use this app password in step 7 of the archive account setup above.

After the transfer completes, you can delete the app password from the same page by clicking the trash icon.

What Happens During and After Transfer

Once linked, the archive account will start pulling emails from the primary account. The transfer speed depends on message volume and server load. For a test account with 75,000 messages, the process took about 48 hours. During this time, the primary account will place transferred messages into the Trash folder. After the transfer is complete, you must manually empty the Trash. In the test, clearing 75,000 messages took about an hour.

After emptying Trash, check your storage usage. In the test, the primary account dropped from 12GB (80% of 15GB) to 0.66GB (0.06GB from Gmail). The archive account now holds all historical emails, while the primary is free for new messages.

Which Messages Are Not Transferred?

Gmail's POP3 import does not move Drafts or Spam. Drafts must be handled manually—you can copy them or discard them. Spam messages are automatically deleted after 30 days, so you can ignore them or manually clean them out. All other messages, including Inbox, Sent, and custom labels, are transferred.

Final Steps After Transfer

To stop the automatic import, log into your archive account, go to Settings > Accounts and Import, and delete the link to your primary account. If you created an app password, delete it as well.

One important note: Google deletes accounts that have been inactive for more than two years. So if you create an archive account, make sure you log into it at least once every two years to keep it active. Otherwise, you could lose all those transferred emails.

By following these steps, you can reclaim your primary Gmail storage without spending a dime. The key is to act before Google fully removes POP3 support later this year.
