How do I get emails older than 12 months?

Last reviewed: September 23, 2026 · Markdown version

Search older_than:1y. Google documents the operator as "Search for emails older or newer than a time period. Use d (day), m (month), or y (year).", with older_than:1y as its own example (Refine searches in Gmail, read 23 September 2026). Type it in the Gmail search box on the web or the phone; there is no menu for it.

Always give a unit

older_than:12m and older_than:1y cover the same span — twelve months is a year. What Google's description does not cover is a bare number: it names the three unit letters and nothing else, so older_than:12 is not a documented form. Include the letter every time.

Combinations that are actually useful

older_than:1y has:attachment larger:10M — old and heavy. larger: and has:attachment are documented on the same Google page, with larger:10M as its example.
older_than:1y category:promotions — a year of marketing, often the easiest year of mail to let go. Read it first all the same.
older_than:2y from:noreply@example.com — everything one automated sender produced, before that sender existed in your attention.
older_than:1y -is:starred -from:me — old mail you never starred and did not send yourself. Google warns that with a minus sign, "conversations with excluded criteria may still appear", because Gmail matches individual messages first — so a thread you starred can still show up.

Before you act on ten years at once

Read the result before you touch it. Old does not mean unimportant: tax records, tenancy agreements, warranties, the receipt for something still under guarantee, and the account-recovery mail for services you have forgotten you use can all sit in exactly that range. Narrowing by sender or by category first is what turns a dangerous sweep into a safe one.

Deletion in Gmail is a two-stage thing, which helps here. Mail goes to Trash and can be recovered for up to 30 days; "After 30 days: The message is permanently deleted" (Delete messages in Gmail, read 23 September 2026) — the timing in detail — so a mistake is recoverable, but only if you notice within the window.

Why this search is worth running even if you delete nothing

It shows you the shape of the mail you have kept for a decade. If a handful of senders turn out to account for most of it, the clean-up is far smaller than it looked.

Where we fit

Adinand Email Cleaner does that shape-finding for you. It groups your Gmail by sender, with the measured size of each group added up from the per-message sizes Gmail reports, so a decade of archive becomes a list of names you can decide about one at a time. It works with Gmail, all the processing happens on your device, and it only ever asks Gmail for headers — never the contents of your messages. Free to try: up to 2,500 emails and 3 auto-trash rules, with 250 more emails added every month (unused monthly emails don't carry over).
