How to Backup Gmail Emails in 2026 (Google Takeout + IMAP)

The short answer

Go to takeout.google.com and sign in with the Gmail account you want to back up. Click Deselect all, scroll to Mail, tick the box, pick Include all messages in Mail, and click Next step. Choose a delivery method (download link email, Google Drive, Dropbox), export type (one-time or every 2 months for 1 year), file size, and format (zip is standard). Click Create export. Google emails a download link when the MBOX archive is ready.

Backing up Gmail is the kind of task most people never do until the moment they lose access to their account and wish they had. Google Takeout makes it free and simple: one form, one click, and Google emails you a complete archive of every message in MBOX format. This guide walks you through a full Gmail backup with Takeout, a quicker IMAP-based option for ongoing sync, and the fix for the two mistakes that cause people to lose data during the export.

Back up Gmail with Google Takeout (the official way)

Google Takeout is the free export tool built by Google. It covers every product in your Google account, but you can narrow it down to just Mail. The result is a downloadable .zip containing an MBOX file you can open in Thunderbird, Apple Mail, Outlook, or any desktop mail client that supports MBOX.

1. Go to takeout.google.com and sign in with the Gmail account you want to back up.
2. Click Deselect all at the top (Google ticks every product by default, we only want Mail).
3. Scroll down the product list and tick Mail.
4. Click All Mail data included under Mail to pick what gets exported.
5. Choose Include all messages in Mail for a full backup, or pick specific labels (Inbox, Sent, custom labels) to shrink the archive.
6. Click OK, then scroll to the bottom and click Next step.
7. Pick a delivery method: Send download link via email (default), Add to Drive, Add to Dropbox, Add to OneDrive, or Add to Box.
8. Pick export type: Export once for a one-time backup, or Export every 2 months for 1 year for rolling backups.
9. Pick a file size (2 GB is a good balance, 50 GB works if you have a fast connection).
10. Choose .zip as the file format (default).
11. Click Create export.

Google starts preparing your archive. Export time depends on account size: small accounts (a few GB) finish in minutes; large accounts (50 GB or more) can take several hours or even a day. Google emails you when the download link is ready. The link stays active for 7 days.

Back up Gmail with IMAP (for ongoing local copy)

If you want a continuously-updated local copy of your Gmail (not just a one-time snapshot), connect an IMAP mail client and let it download every message to disk. Thunderbird is the common pick because it is free and cross-platform.

1. In Gmail, go to Settings, click See all settings, click the Forwarding and POP/IMAP tab.
2. Under IMAP access, pick Enable IMAP, then click Save Changes.
3. If you have two-factor authentication on (you should), go to myaccount.google.com/apppasswords and generate an App password for Mail. Copy it.
4. Install and open Thunderbird.
5. Click Account Settings, then Account Actions, then Add Mail Account.
6. Enter your name, Gmail address, and the App password you generated.
7. Thunderbird auto-detects the IMAP settings. Click Done.
8. Right-click the account in the sidebar, click Subscribe, tick every folder you want to sync locally, click OK.
9. Thunderbird starts downloading every message. Full sync of a 10 GB inbox can take a few hours.

From this point on, every email that arrives in Gmail also lives on your hard drive. If your Google account is ever locked or deleted, you have a complete copy. The Thunderbird profile folder (contains all the downloaded mail) can itself be copied to an external drive as a second layer of backup.

Open and read the MBOX backup file

Google Takeout gives you an MBOX file inside the .zip archive. MBOX is a standard mail format readable by many clients.

1. Unzip the Takeout .zip to a local folder. The structure will be Takeout/Mail/ containing one or more .mbox files.
2. Open Thunderbird (install if needed).
3. Install the ImportExportTools NG add-on (free, from addons.thunderbird.net).
4. In Thunderbird, right-click Local Folders in the sidebar, pick ImportExportTools NG, then Import mbox file.
5. Pick Import directly one or more mbox files, browse to your Takeout .mbox file, click Open.
6. The archive opens as a new folder under Local Folders. You can search, read, and forward any email as if it were a live Gmail folder.

On macOS, Apple Mail can also open MBOX files directly: File, Import Mailboxes, Files in MBOX format. On Windows, Outlook does not natively open MBOX; use Thunderbird as the reader.

Automate a monthly backup schedule

Takeout’s “Export every 2 months for 1 year” covers you for a year, after which the schedule stops. For a longer-term rolling backup, combine Takeout’s email delivery with a Gmail filter that saves download links to a dedicated label.

1. Set up a Takeout export with Export every 2 months for 1 year and delivery method Send download link via email.
2. In Gmail, create a filter: From noreply@google.com, Subject Your Google data is ready, Apply the label Takeout backups.
3. Set a calendar reminder for day 1 of every third month (if 2-month cadence) to download the archive to external storage before Google’s 7-day link expiration hits.
4. After the 1-year schedule ends, go back to Takeout and start a fresh 1-year schedule.

If you want full automation without calendar reminders, pick Add to Drive as the Takeout delivery method, then set up a Google Drive sync client (Backup and Sync or Drive for Desktop) to automatically pull the archive to your local disk whenever it appears.

Troubleshoot a Gmail backup that failed or seems incomplete

The two most common issues with Takeout exports and how to fix them.

Cause 1: the archive size is smaller than your Gmail usage shows. Takeout exports your mail only, not attachments stored outside Gmail (links to Drive files, for example). If your inbox has heavy Drive-linked attachments, the Mail archive is smaller than the Gmail storage number. To export those attached Drive files too, add Drive to the Takeout export alongside Mail.

Cause 2: the download link expired before you downloaded. Google’s email links expire after 7 days. If you miss the window, go back to takeout.google.com and start the export again. Google does not re-generate expired links. For large accounts, pick Add to Drive instead of email delivery so you have more time to grab the file.

Bonus: the export is stuck “preparing” for more than 24 hours. For accounts over 50 GB this is normal. If it has been more than 48 hours with no update, go to takeout.google.com, find the stuck export in the list, click the three-dot menu, and cancel it. Start a fresh export with a smaller file-size chunk (2 GB instead of 50 GB) so Google splits it into more manageable archive pieces.

We are hoping this backup routine spares you from the panic of a locked account. If you have questions about restoring the MBOX into a specific client, drop them in the comments below and we will expand the restore section.
