You think you own your inbox. You don't. Not really. If Google decided to lock your account tomorrow because of a "suspicious activity" flag or a glitch in their automated TOS bot, years of bank statements, sentimental photos, and business receipts would just... vanish. It happens. Honestly, it's terrifying how much we trust a free service with our digital lives. Exporting emails from Gmail isn't just a technical chore you do when switching jobs; it’s basically digital insurance.
Google makes it look easy. They give you this tool called Takeout. But if you’ve ever actually used it, you know it’s a bit of a mess. You get these massive .mbox files that Windows or Mac can't open natively, or the download link expires before you can even click it. It’s frustrating.
We’re going to walk through how this actually works. No fluff. No corporate speak. Just the reality of getting your data out before something goes sideways.
The Google Takeout reality check
Google Takeout is the "official" way to handle exporting emails from Gmail. It’s a tool built under the pressure of data portability laws like the GDPR in Europe. Because of that, it’s designed to be compliant, not necessarily user-friendly.

When you head over to Google Takeout, the first thing you’ll notice is that every single Google service is selected by default. You don’t need your YouTube watch history or your Google Maps "timeline" right now. You just want the mail. Deselect everything. Then, scroll down until you find Mail.
Here is where people mess up.
Most users just click "All Mail data included" and move on. Don't do that. If your inbox is 15 years old, you’re looking at a 50GB file that will likely fail during the download process. Instead, click that button and filter by labels. Maybe you only need your "Tax" label or your "Family" folder. Limiting the scope makes the process way more reliable.
Once you request the export, Google starts "preparing" your files. This is the part that drives people crazy. It can take minutes. It can take days. There is no progress bar. You just get an email eventually saying it’s ready. If you have a massive archive, Google will split the zip files into 2GB chunks by default.
Pro tip: Change that 2GB setting to 10GB or 50GB if you have a fast internet connection. Dealing with fifty different 2GB zip files is a special kind of hell that nobody should endure.
Dealing with the dreaded MBOX format
So, you’ve finished exporting emails from Gmail and you have a file ending in .mbox sitting on your desktop. You double-click it. Nothing happens. Or worse, Notepad tries to open it and your computer freezes for five minutes.
The MBOX format is basically one giant text file containing every single email in that category, stacked on top of each other. It’s great for archival purposes because it’s a standard format, but it’s useless for a quick "I need to find that receipt from 2019" search.
To actually read these things, you need a third-party client.
- Thunderbird: It’s free, open-source, and has been the gold standard for this for decades. You can import the MBOX file and browse it just like a live inbox.
- Apple Mail: If you’re on a Mac, you can technically import MBOX files, but it’s finicky. It often loses the folder structure.
- MBox Viewer: There are lightweight "viewers" out there if you don't want to install a full mail client.
One thing people rarely talk about is the metadata. When you export, Google keeps the headers—the IP addresses the email passed through, the exact timestamp down to the millisecond. This is vital if you’re doing this for legal reasons. If you’re just trying to save a few photos from Grandma, it’s overkill, but it’s better to have too much data than too little.
Why you might want to avoid Takeout entirely
Takeout is a snapshot. It’s a photo of your inbox at 10:42 AM on a Tuesday. By Wednesday, it’s outdated.
If you’re exporting emails because you’re moving to a new provider—like Outlook or ProtonMail—Takeout is actually the hard way to do it. Most modern email services have an "Import" tool. You give them your Gmail credentials, and they use a protocol called IMAP to fetch everything.
IMAP is basically a bridge. It lets one server talk to another.
The downside? It’s slow. Like, really slow. If you have 100,000 emails, an IMAP transfer might take a week. But it’s "set it and forget it." You don't have to manage giant zip files or worry about MBOX compatibility.
There’s also the "Forwarding" trick. If you only care about new emails going forward, just go into Gmail settings and set up a forwarding address. But for the old stuff, you’re stuck with either a bulk export or a slow sync.
The "Secret" Google Workspace Method
If you’re using a business account (Google Workspace), the rules change. Your admin might have disabled Google Takeout. Seriously. Many companies don't want employees walking away with a local copy of their entire professional history.

If you’re the admin, you have access to the Data Export tool. This is different. It exports the data for everyone in the organization to a Google Cloud Storage bucket. It’s a powerhouse tool, but it’s not for the faint of heart.
For individual Workspace users who find Takeout blocked, your best bet is usually the IMAP method mentioned earlier. Enable IMAP in your Gmail settings, then use a desktop client like Outlook or Thunderbird to "drag and drop" emails from your Gmail account to a "Local Folder" on your computer. It’s tedious. It works.
Security risks: What nobody warns you about
This is the part where I get a bit serious.
When you finish exporting emails from Gmail, you are holding a completely unencrypted, plain-text file of your entire life. If you leave that mail.mbox file in your Downloads folder or on an unencrypted USB drive, anyone who gets their hands on it has everything. Your password reset links, your private conversations, your travel itineraries—all of it.
If you’re going to back up your email, you must encrypt the destination.
- On Windows: Use BitLocker or Veracrypt to secure the drive.
- On Mac: Use FileVault.
Don't just upload that MBOX file to another cloud service like Dropbox or iCloud without a password. You’re just moving the vulnerability from one basket to another.
Actionable steps for your archive
Don't wait until you get that "Storage Full" notification or a weird account lockout message. Data loss is a "when," not an "if," in the long run of the internet.
Start by doing a "mini-export."
Go to Google Takeout. Deselect everything. Select Mail. Use the "Label" filter to pick just one year of emails. Choose the .zip format and 2GB size. Hit export.
Wait for the link. Download it. Try to open it in a tool like Thunderbird.
Once you know you can actually read the data, then go back and do the full dump. Do this every six months. Label the files clearly: Gmail_Archive_Jan_2026.mbox.
Storage is cheap. Memories and legal records aren't. Take the twenty minutes to grab your data. You’ve spent years building that inbox; don’t let it exist only on someone else's server.

Move the archive to a physical external drive. Store a second copy in a different physical location if you’re really serious. That’s how you actually own your digital footprint.
The process is clunky, sure. Google doesn't really want you to leave. But having that file on your desk feels a lot better than trusting a "Sign-in" button that might one day stop working.
