How long does Gmail keep old emails?

Last reviewed: September 25, 2026 · Markdown version

Mail you have not deleted stays in a personal Gmail account with no expiry date, as far as Google's help pages go: the storage page limits you by gigabytes, not by age. Every account "includes up to 15 GB of storage, which is shared across Gmail, Google Drive, and Google Photos" (How your Google storage works, read 25 September 2026), and neither that page nor Google's inactive-account policy (cited below) sets an age limit for kept mail. Three things can end it, and all three are on Google's own pages.

1. You delete it: 30 days

A deleted message goes to Trash first. "Up to 30 days after deletion" you can still find and restore it; "After 30 days: The message is permanently deleted. You can't recover the message" (Delete messages in Gmail, read 25 September 2026). Archived mail is different: it has left the inbox but not the account. Archiving versus deleting covers that choice.

Spam is the gap. Google's spam page explains how to delete spam yourself ("Delete all spam messages now") but gives no retention period for the folder (Report spam in Gmail, read 25 September 2026). If something you want is sitting in Spam, move it today rather than guessing how long it will stay.

2. The account goes unused for two years

Google's policy: an inactive account "is an account that has not been used within a 2-year period", and Google "reserves the right to delete an inactive Google Account and its activity and data if you are inactive across Google for at least two years". Activity is broad — "Reading or sending an email" counts, as do searching and watching YouTube while signed in — and Google says it notifies the account and any recovery address first (Inactive Google Account Policy, read 25 September 2026).

Two details on that page matter here. The policy "doesn't apply to any Google Account that was set up for you through your work, school, or other organization". And there are exceptions — for example, an account used to buy a Google subscription "that is current or ongoing" counts as active. An old address you still use now and then is safe on this count; one you abandoned years ago is not.

3. The account is over its storage for two years

If you stay over quota "for 2 years or longer", Google says "all of your content in your Google Account may be removed including in Gmail", after contacting you "at least 3 months before content is eligible for deletion" (the How your Google storage works page). Long before that, a full account stops mail arriving: Google lists that "Your ability to send and receive email in Gmail can be impacted" once you are over. What to do when that happens.

Work and school accounts

Here the organisation decides. Google's administrator documentation says that "By default, Google Workspace data stays in user accounts until the user or admin deletes it", and that admins can set retention rules in Google Vault that keep mail longer than users would, or "purge data once it's no longer needed" (How retention works, read 25 September 2026). If old work mail vanishes on a schedule, a rule like that is the likely reason, and your admin is the one who can tell you.

If you want a copy that does not depend on any of this

Google Takeout exports what is still there: "You can download data that hasn't been deleted", and the download includes "Message content", "Message headers" and "Attachments" (Export your data from Gmail, read 25 September 2026). For mail you cannot afford to lose to a lapsed account, an export kept somewhere else is the only arrangement none of the three rules above can touch.
