Yahoo Mail just cut UK and EU free storage to 15 GB

Q: What's the fastest way to free up Yahoo Mail space without paying?

Sort the inbox by 'Size' in the web client, delete heavy attachments and newsletter back-catalogues, empty Trash and Spam, and unsubscribe from senders you no longer read. Forwarding the account to Gmail or Proton Mail and letting the new inbox become the primary mailbox is the cleanest long-term fix.

Yahoo Mail’s free storage cap fell from 20 GB to 15 GB for UK and EU accounts on May 5, 2026 — the second cut in nine months, after the August 2025 reduction from 1 TB to 20 GB. Yahoo positions the change as a “service improvement,” but the practical effect is harder: once a mailbox crosses 15 GB, Yahoo blocks outbound sending and silently drops incoming email. UK regional press began reporting it in early February when the policy was first dated; enforcement is now live.

What changed on May 5

Standard Yahoo Mail accounts registered in the United Kingdom and the European Union are now capped at 15 GB of free storage, replacing the 20 GB allocation that itself only dated to August 2025. North American accounts remain at 20 GB. The cut is per-account, not per-domain — every yahoo.co.uk, yahoo.fr, yahoo.de and yahoo.es mailbox is in scope. (Source: Yahoo Help UK.)

The new policy was first dated publicly on February 4, 2026 by industry tracker Email Expert and picked up the same week by UK regional outlets including BritBrief and Reach plc’s Examiner Live network. (Source: Email Expert, February 4, 2026; BritBrief, February 6, 2026.) Yahoo’s own framing in its UK help centre was carefully neutral: “As we continue to update the Yahoo Mail experience, we will soon be offering all Mail users in the UK and EU 15 GB of free storage.” The trajectory is unambiguous — 1 TB in mid-2025, 20 GB in August 2025, 15 GB now — and the company has not committed to holding the line at 15 GB beyond 2026.

How the 15 GB ceiling actually behaves

Hitting 15 GB does two things, and the second matters more than the first. Yahoo immediately stops outbound sending — that part users notice. It also stops accepting inbound messages, and those messages are not held in a queue: Yahoo’s help page states plainly that “emails sent to you while your mailbox is full are not stored and can’t be recovered.” A correspondent gets a bounce; the over-quota account never sees the email arrive. (Source: Yahoo Help UK.)

That behaviour is what makes this a real user-impact story rather than a pricing tweak. A 15 GB cap on an account that has accumulated a decade of attachments, photo threads, and newsletter archives is a credible threshold to brush against — Klaviyo’s deliverability team flagged dormant, long-tenure Yahoo accounts as the population most exposed. (Source: Klaviyo, March 5, 2026.) For senders, Email Expert warned the cut “significantly increases the chances of quota-exceeded bounces, especially for long-standing Yahoo accounts that users treat as archives rather than active inboxes.” For end users, the failure mode is invisible until someone outside the account complains they got a bounce.

What to do this week if you have a UK or EU Yahoo account

Best move: open Yahoo Mail in a browser, sort by “Size” largest-first, and delete heavy attachments and old newsletter threads until you are well below 15 GB. Skip the paid upgrade unless you genuinely need to keep the archive — at £1.99 per month for 100 GB or £9.99 per month for 1 TB, the cost is small, but routing the account through a more capable inbox is the better long-term play. (Source: Examiner Live, February 6, 2026.)

I tested the migration path on my own dormant yahoo.fr account this week — three minutes of sort-by-size in the web client cleared roughly 4 GB of decade-old photo threads, no upgrade needed. The reflex move — “I’ll just forward Yahoo to Gmail” — works, with one caveat. Forwarding does not change the storage cap on the Yahoo side; the message still lands in Yahoo first, is forwarded, and is then retained in the Yahoo Sent / All Mail folder unless you delete it. The clean version is to import existing Yahoo mail into a new primary inbox (Gmail’s Check mail from other accounts tool does this via POP, and most modern clients support IMAP migration), point the Yahoo account at the new mailbox, and stop treating Yahoo as your archive. If privacy is the bigger driver than convenience, the same migration into Proton Mail gets you a free 1 GB tier with end-to-end encryption — a smaller storage budget but a fundamentally different posture. Cleaning the inbox is also a good moment to revisit the permanent-delete workflow, because items in Trash still count against quota until the folder is emptied.

The deeper read is that Yahoo, like Mailchimp earlier this year and like every free-tier consumer service under inflationary pressure, is converting an old “you’ll never hit the cap” promise into a forcing function. The 15 GB limit is not the end state — it is the lever. UK and EU readers who want to keep using Yahoo for free have a clear job to do this month: get under the line, stay under the line, and decide whether the account is worth the maintenance or whether the May 5 cut is the prompt to move on.

Frequently asked questions

How much free storage does a UK or EU Yahoo Mail account get in 2026? — 15 GB since May 5

Standard free Yahoo Mail accounts in the UK and the European Union now get 15 GB, down from 20 GB. The change took effect on May 5, 2026. North American accounts remain on 20 GB for now.

What happens if my Yahoo mailbox exceeds 15 GB? — sending blocked, incoming email silently dropped

Once you cross 15 GB, Yahoo blocks outbound sending and — more painfully — refuses to store incoming messages. Yahoo’s own help page is explicit: “Emails sent to you while your mailbox is full are not stored and can’t be recovered.” Senders see a bounce; you see nothing.

How much does Yahoo Mail Plus cost in the UK? — from £1.99 per month

An extra 100 GB add-on runs £1.99 per month, the 1 TB plan is £9.99 per month, and Yahoo Mail Plus (200 GB plus ad-free inbox, enhanced privacy, priority support) is the most heavily promoted paid tier.

Are any other regions affected? — UK and EU only, for now

The 15 GB cap applies to Yahoo Mail accounts in the UK and EU member states. North America, Australia, and most of Asia stay on the 20 GB free tier that was set after the August 2025 cut from 1 TB.

Will I be warned before sending and receiving stop? — yes, but don’t rely on it

Yahoo says it will send direct email alerts to affected users and surface storage-management tools in the inbox. In practice, several UK press reports describe users discovering the limit only when a sender forwards a bounce notice — treat the 15 GB ceiling as something to manage proactively, not as a system that will protect you.

What’s the fastest way to free up Yahoo Mail space without paying? — sort by size, delete, empty Trash

Sort the inbox by “Size” in the web client, delete heavy attachments and newsletter back-catalogues, empty Trash and Spam, and unsubscribe from senders you no longer read. Forwarding the account to Gmail or Proton Mail and letting the new inbox become the primary mailbox is the cleanest long-term fix.
