The Gmail Storage Squeeze — And Why You Should Own a Copy

For years the deal was simple: sign up for a Google account, get 15 GB of free storage shared across Gmail, Drive, and Photos, and never think about it again. That deal is quietly changing — and it's a good moment to ask an uncomfortable question. If Google owns the only copy of a decade of your email, what happens when the free tier moves out from under you?

What Actually Changed

In May 2026, users and reporters spotted Google testing a new storage policy for newly created accounts in certain regions: 5 GB of free storage by default instead of 15 GB. To unlock the full 15 GB "at no additional cost," you're prompted to add a phone number to the account. Google's own wording shifted too — from "Your Google Account comes with 15 GB of cloud storage at no charge" to "up to 15 GB." (9to5Google, TechRadar.)

To be precise about it, because the headlines weren't always: this is a test, it targets new accounts in select markets, and if you already have an account with 15 GB, nothing is being taken away from you today. Google says the experiment is about service quality and pushing account-recovery security. The reporting consistently points at the same underlying pressure — the rising cost of AI and cloud infrastructure (Cybernews).

We're not here to catastrophize a limited test. We're here to point at the direction of travel. "Up to 15 GB" is not the same promise as "15 GB." Free tiers get smaller, or get gated behind a phone number, or behind a paid plan — and the one thing every version of this story has in common is that the email lives on someone else's server, under terms that can be revised without your sign-off.

The Part Nobody Mentions: Inactivity Deletion

The storage cap is the headline, but there's a quieter policy that matters more for anything you consider an archive. Since December 2023, Google can delete an entire consumer account — and everything in it, Gmail messages, Drive files, Photos, and the address itself — if it goes unused for two years (Google's own storage-management page).

Think about what that means for the old account you keep "just in case." The one with your university records, your first freelance invoices, a receipt for something still under warranty, the last emails from someone you've lost. If you're not signing in, the clock is running. An inbox is a place mail arrives. It was never designed to be the safe where you keep the things you can't get back.

Where MailVault Comes In

MailVault is a desktop app that connects to your Gmail and keeps a complete, permanent copy of it on your own computer. You sign in with Google — real OAuth2, no app passwords, no IMAP server settings to hunt for (we wrote up that flow here) — and MailVault pulls your mail down into local files you control.

The important design decision is the storage format. Every message is saved as a standard .eml file in a Maildir-style folder tree on your disk. That's not a proprietary database you can only open inside our app. .eml is the raw RFC 822 email format — the same thing every mail client on earth understands. Your archive is a plain folder of plain files:

~/MailVault/
  [email protected]/
    INBOX/
      1699887342.a1b2c3.eml
      1699890021.d4e5f6.eml
    Sent/
    Receipts/        ← your own Gmail labels, preserved as folders
    Family/
    ...

Open one in Apple Mail, Thunderbird, Outlook, or a text editor — it just opens. Back the folder up to an external drive, a NAS, or a cloud folder of your choosing. Copy it to a new machine in ten years. Nothing about reading your own email depends on MailVault still existing, on a subscription being current, or on a server staying online. That's the whole point.

How This Answers the Squeeze

Line the concerns up against what a local copy actually does:

Free tier shrinks. Once your mail is archived locally, the messages you no longer need live on Google's servers can be deleted there to reclaim space — while the copy on your disk stays complete. Your inbox becomes a working surface, not the only vault. Your 5 GB (or 15, or whatever the number lands at) stops being a countdown you're helpless against.

Inactivity deletion. An account you've fully archived can lapse without taking your history with it. If Google reclaims a dormant account two years from now, you've lost an address — not your records.

Lock-in and lost access. Forgotten password, a security flag on the account, a policy dispute, or simply wanting to leave Gmail someday — none of it touches a folder of .eml files sitting on your own drive.

We think this is the honest version of email ownership, so we'll be honest about the boundary too: MailVault keeps a copy, it doesn't run your mail. You still send and receive through Gmail. What changes is that "delete to save space" and "let this old account lapse" stop being irreversible, because the archive isn't the thing you're deleting.

Local First, Not Local Only

One more thing worth being clear about, because it's easy to assume the pitch is "distrust the cloud." It isn't. The cloud is genuinely convenient, and Gmail is a genuinely good inbox. The problem was never that a copy lives on Google's servers — it's that, for most people, it's the only copy, governed by terms they don't set.

MailVault's answer is to flip which copy is the anchor. The authoritative, permanent archive is the one on hardware you own, in a format that outlives any single app. Cloud redundancy and sync are things you add on top for convenience — not the foundation you're betting your history on. A shrinking free tier is a much smaller story when the free tier was never where your archive lived.

Getting a Copy Today

If any of this hit a nerve — the old account you should really back up, the storage bar creeping toward full — the fix is about fifteen minutes of setup. Download MailVault, sign in with Google, and let it pull your mail down into a folder you own. Then do the thing you've been meaning to do for years: make a copy of your email before the terms change again.
