A patient guide to leaving Gmail without losing fifteen years of email

This guide is for someone who has been on Gmail for a long time, has a lot of important email there, has been told they should leave, and has no idea where to start. It assumes you are not technical. It assumes you have things to lose. It assumes you would rather take a careful month than a chaotic weekend.

We're going to move you to Proton Mail. We'll explain why. We'll do it in stages. At the end you will own your email.

Before we start, the version of you that signed up for Gmail when it was a clever new thing — when invitations were a status symbol, when fifteen gigabytes felt infinite, when the tradeoff was unclear — made a reasonable choice with the information available at the time. Nothing in this guide is about shame. Nothing here is your fault. The deal has changed, and the change was not in your favor, and now we change with it.

What's actually wrong with Gmail.

Quickly, so we don't have to come back to it. Gmail isn't a service you use. It's a fixture inside Google's broader business. Your inbox is scanned to build a model of you — your habits, your purchases, your travel, your relationships, your finances, your health concerns. That model is sold to advertisers in the form of attention placement and used internally to train Google's other products, including the AI products that increasingly compete with the work you do.

When you grant a third-party app access to your Gmail (a calendar tool, a project management tool, a CRM), that access is rarely revoked when you stop using the tool. There is, on average, a long tail of services that have read access to your inbox right now that you forgot existed. Many of those services have been bought, sold, or shut down since you authorized them; in the shuffle, your data went somewhere you can't follow.

The Google account that holds your Gmail also holds: every place you've been (Maps history), every YouTube video you've watched, every search you've made, every Google Doc you've written, your contacts, your calendar, your photos, the assistant transcripts of every voice command, and the device fingerprints of every device you've signed into. They form a single profile. The profile cannot be partly deleted in any meaningful sense. The export options exist because regulators required them, and they produce files that are technically your data and practically not.

This is the system you're leaving.

Why Proton specifically.

Proton is a Swiss company. It is structured as a non-profit foundation. Its email is end-to-end encrypted, in a way where Proton itself cannot read your messages even if compelled. Switzerland's privacy laws are strict, and Proton has spent a decade in court defending them. The company sells one product — privacy — to people who pay for it. There is no advertising business attached. There is no model being trained on your inbox.

Proton also does the boring things well. The web client looks like email. The mobile apps work. Calendar, drive, and VPN are part of the same ecosystem at no extra cost on the paid plans. You can use a custom domain. You can have aliases. You can import from Gmail with their official tool.

If you only ever move one service in your life, move email. If you only ever move email to one provider, move it to Proton.

Stage one: get a Proton account, but don't switch anything yet.

Sign up for a Proton account. The free tier exists; if you have any meaningful volume, the paid tier is roughly the price of a streaming service per month and unlocks the storage and features you'll actually want. Pay for a year. The friction of canceling something at the end of a year is much lower than the friction of running out of storage in week three and abandoning the project.

Pick your address carefully. firstname@proton.me if it's available. A custom domain (firstname@yourname.com) if you have one, or are willing to register one — domains are a few dollars a year and survive every subsequent migration of every service. Owning your domain is itself a small form of ownership, and it means if you ever leave Proton too, your address goes with you.

Don't tell anyone about the new address yet. Don't update any accounts. We're just establishing a place for the email to land.

Stage two: import the past.

Use Proton's Easy Switch importer. You sign in with your Google account, grant access to your Gmail, and Proton pulls everything across — folders, labels, attachments, the lot. This takes hours to days depending on how much email you have. Fifteen years of inbox can take two or three days; that's normal.

While it runs, do one other thing in Gmail: go to your Google Account → Security → Third-party apps with account access. Look at the list. Most of those apps still have read access to your inbox right now. Revoke every one you don't actively use. There will be more than you expect.

When the import finishes, your fifteen years of email lives in two places: Gmail and Proton. Don't delete anything yet.

Stage three: forward, don't switch.

In Gmail, set up forwarding to your new Proton address. Every new email that arrives at Gmail gets a copy delivered to Proton. You're not telling anyone the new address yet. You're just making sure that anything new that arrives reaches both inboxes.

This is the most important stage and most people skip it. The forwarding stage is what makes the migration safe. If something breaks at Proton, you still have Gmail. If you forget to update an account, the email still reaches you. The forwarding is your safety net for the next month or two.

Use Proton as your primary inbox for new email. Reply from Proton. Get used to the interface. Set up the mobile app. Notice what's different. Most of what's different is the absence of clutter.

Stage four: update accounts, in priority order.

Now we update the email address on your accounts. Don't try to do this all in one weekend. Spread it over a month. The order:

First, the accounts that matter most. Bank, brokerage, government services, identity documents, primary employer's HR system, your mortgage or rent provider, your phone carrier. These are the accounts where losing email access is genuinely catastrophic. Update them first, while you still have Gmail forwarding as a backup.

Second, the accounts you use weekly. Whatever services you log into without thinking about it. Streaming. Shopping. Cloud storage. Two-factor codes will arrive at the new address once these are updated, and that's exactly what you want.

Third, everything else, as you encounter it. You'll get an email at Gmail from some service you forgot you had. Click through, sign in, change the email. Move on. Over six months, this trickle will slow to nothing.

Stage five: live in Proton for thirty days.

Don't close Gmail yet. For the next thirty days, do all your email in Proton. Watch the Gmail forwarding for stragglers. Update accounts as their emails arrive at Gmail. The day will come when you go a full week without anything important arriving at the old address.

That's the signal.

Stage six: archive Gmail, then close it.

Use Google Takeout to export your Gmail one last time, into the standard MBOX format. Save the file somewhere safe — an external hard drive is fine. This is your backup of the past. You almost certainly won't need it. Having it lets you proceed with confidence.

Then go to Google's account deletion page, and close the account.

This part takes thirty seconds and feels strange. Fifteen years of an account, gone. But the email itself isn't gone — it's in Proton, and it's also in the MBOX file on your drive. Only the Gmail is gone. The thing that was scanning, indexing, and selling your inbox is gone. The email you actually cared about is still yours.

Some people skip this final step and leave Gmail running indefinitely, just in case. That's fine, too — though Google still scans inactive accounts, so the data extraction continues whether you log in or not. We mention it because the choice should be conscious, not default.

Stage seven: tell people.

Email the dozen most important people in your life with the new address. Don't make a production of it. One paragraph, friendly, no preaching. Hi — quick note that my email has moved to [new address]. Old one will keep working for a while. No need to do anything; just thought you should know.

Most people won't react. A few will ask why. Have a one-sentence answer ready. I wanted to own my email. That's it.

What you've gained.

You now have an inbox that is not being scanned. The contents of your messages cannot be read by the company providing the service. Your address moves with you if you ever change providers (especially if you used a custom domain). The advertisements that used to surround your email are gone. The "smart" features that read your content to suggest replies are gone, and you will not miss them.

You also have a small foothold in the larger move that this article is part of. You proved to yourself that this was possible. The hardest service to leave is usually the first. After email, calendar is easy. After calendar, photos are doable. After photos, the rest is mostly choice.

That's the point of starting here. Not because email is the worst, but because email is the move that proves the rest are possible.

You did this in stages, on your own timeline, without losing anything. The version of you who signed up for Gmail in 2009 would be impressed.
