Yahoo Mail Mailroom is independent · not affiliated with Yahoo

Stop paying rent for ghost email!
We are privacy first.

Yahoo cut free storage to 15 GB in the UK and EU. Go over it and you can lose the ability to send or receive email until you delete mail or start paying monthly. Mailroom shows you what is safe to clear first, on your own device, before you pay anyone anything.

From the person who built it

That mailbox is mine.

Yahoo told me I was over the limit. I started clearing my mailbox, then an hour later I thought — hold on. What if instead of clearing it, I did the opposite? I put the cleared mail back from the Trash on purpose, because I wanted to see exactly what Yahoo does to an account that stays over, and what it would cost me to give in and pay monthly instead. That is Yahoo's own Trash, not a Mailroom feature — Mailroom does not restore mail. This is how Mailroom was born in my mind, and then I started drafting the product.

The numbers shown on this page are the same mailbox at different points. The screenshots below show it at 15.4 GB, over the 15 GB limit. The video shows it at 32.7 GB, after I put the mail back. One account, one year, two readings.

Initially the KeepSafeTM engine could identify about 2 GB of mail we could safely delete. We worked hard and improved it — a bit more, then more, then more again.

Mailroom now found 21.7 GB of that 32.7 GB safe to clear. And I have not paid Yahoo a single penny for storage — I have years of room left.

The notices

Yahoo will give you a date. Then it moves.

Yahoo gives you a date. Mine said 29 July in one banner and 22 August in another, on the same account in the same week, and an email called it a final reminder. Whatever yours says, the arithmetic does not change: clearing the junk is cheaper than renting space for it.

Yahoo Mail banner: Your mailbox storage is full, 102.7 percent, 15.4 GB of 15 GB. Upgrade for more storage or free up space within the next 30 days; if your storage is full after 22 August you will not be able to send or receive emails. Buttons: Add storage, Manage storage.
“Your mailbox storage is full — 102.7%, 15.4 GB / 15 GB.” Free up space “within the next 30 days”, and “if your storage is full after 22 August, you won’t be able to send or receive emails”. Yahoo’s offer is Add storage or Manage storage. Real notice from a personal Yahoo account, July 2026. Mailroom is independent and not affiliated with Yahoo.
Yahoo Mail banner: Your mailbox storage is full. Upgrade for more storage or free up space within the next 15 days; if your storage is full after 29 July you will not be able to send or receive emails. Button: Add storage.
The same account, the other interface: free up space “within the next 15 days”, full “after 29 July” and you lose send and receive. The first banner counted 30 days, to 22 August. Real notice from a personal Yahoo account, July 2026. Mailroom is independent and not affiliated with Yahoo.

Act on the date in your own mailbox, not on ours.

How it works

Four calm steps. You stay in charge the whole way.

No bulk-deletion roulette. Mailroom scans, shows you what is taking space, and waits for your go-ahead before anything is removed.

1
Connect your Yahoo account
Sign in with an app password. Mailroom never stores your main credentials, and nothing is deleted at this stage.
2
Scan and review
See where the space went — by sender, category and age — with the bulk and promotional mail that is safe to clear surfaced for you.
3
Delete with confidence
Approve a cleanup and watch the space come back. Mail goes to Trash first by default, where your provider’s own retention applies.
4
Upgrade only if you want to
The free trial is a real demo. Keep going with a one-time yearly licence — or simply stop. No subscription either way.
KeepSafeTM engine

Your mail never leaves this device. Scanning, sorting and deleting all happen on your device. What does leave is small, never your mailbox, and listed in full — every channel, right here.

Privacy-conscious by design. KeepSafeTM triages email using message metadata — the envelope: sender, size, date, and attachment names, types and sizes. Never the message body, never the file contents, and never by shipping your mailbox to a server to be read.
Built to minimise what leaves your device. We never see your messages, senders, subjects or folder names. Those stay on your device.
You stay in control. KeepSafeTM surfaces what is safe to review and clean up. The decision to delete is always yours.
Why Mailroom

A careful tool for a frustrating problem.

Mailroom is built around outcomes, not features — reclaim space, reduce clutter, and trust every deletion.

Review before delete

See exactly what goes — before anything goes.

Every cleanup is a list you can read: who the mail is from, how much space it takes, and why KeepSafeTM thinks it's safe to clear. Uncheck anything. Nothing is removed until you say so, and mail sent to Trash stays there under your provider’s own retention rules.

Reclaim space
Get back under your limit
Find the bulk and promotional mail quietly eating your quota, and clear gigabytes in one reviewed pass.
Reduce clutter
Years of noise, sorted
Group by sender, category and age so the worst offenders are obvious — instead of scrolling forever.
Stay safe
Recoverable by default
Cleanups go to Trash first, under your provider’s own retention rules. Permanent removal is a separate, deliberate choice.
No pressure
No subscription
A one-time yearly licence keeps you going. Nothing renews silently, and nothing nags you to upgrade.
Honest tooling
Slow delete, told plainly
Providers throttle bulk deletion, so Mailroom is honest about pace and shows real progress instead of a fake spinner.
Plain language
No jargon, ever
No header strings, no protocol acronyms. Just clear words about your mail and the space it's taking.
Pricing

Try it free. Then pay once for the year.

You pay once, for a year. Yahoo’s answer to a full mailbox is rent — billed every month, for as long as you keep the mail, and it does not remove a single dead newsletter. This is the other answer.

Scope & roadmap

Yahoo first — on purpose.

We’d rather do one provider properly than several badly. Yahoo Mail is the one we support today.

Available now
Yahoo Mail
Connect, scan, review and reclaim — the full Mailroom experience, focused on getting Yahoo cleanup right.
Planned · directions, not promises
More email providers
Yahoo is the only provider supported today. Next on the roadmap: Microsoft accounts — outlook.com, hotmail.com, live.com and msn.com, including regional variants such as hotmail.co.uk — then gmail.com, and icloud.com after that. Directions, not release dates: we would rather do one properly than four badly. More to be announced.
Planned
Migrate between providers
Move mail from one provider to another, with the same review-first approach.
Planned

FAQ

Straight answers.

Nothing is deleted without your review, and you choose where it goes. Send it to Trash and it sits in your Yahoo Trash, where you can put it back from Yahoo Mail itself — on Yahoo’s terms and Yahoo’s timing, not ours. Choose permanent and it is gone for good. Mailroom has no restore button, deliberately: what happens after a delete depends on things we do not control, and a button that cannot keep its promise is worse than no button. Mailroom keeps the record of what was removed.
Because the mail is almost certainly still in your Yahoo Trash. Unless you chose Permanent delete when Mailroom asked, a cleanup goes to Trash — the safer choice, since you can still put things back — and Yahoo keeps counting Trash against your storage until it is emptied. To see the space come back now, open Yahoo Mail, find Trash in the folder list and use its Empty Trash control; Yahoo also empties it on its own after a while, and the meter can take a few minutes to catch up. Mailroom deliberately never empties your Trash for you — it only touches the mail you reviewed. The full walkthrough is on the support page.
You may see a warning the first time you run the installer, and we would rather you heard it from us than met it cold. Windows shows “Windows protected your PC”.

That is SmartScreen, and it is expected for a new publisher. Every Mailroom release is code-signed with a standard OV code-signing certificate issued to Mailroom-LTD, so the permission prompt names us as the publisher. But SmartScreen trusts publishers by reputation, not by certificate alone, and a new certificate only earns that as installs accumulate. Until ours has, the warning is about how few machines have seen the file, not about anything found inside it. To continue: click More info, then Run anyway.
Installing Mailroom on Windows: the mailroom_0.2.0_Win64 download, the SmartScreen “Windows protected your PC” warning, clicking More info then Run anyway, and the Mailroom 0.2.0 installer opening.
The prompt you’ll see, and how to pass it: More info → Run anyway.

The warning fades as more people install Mailroom. We are not going to pretend it does not happen in the meantime.
No — almost certainly a false alarm, and you do not have to take our word for it. We virus-scan every release we publish, and the download page lists each file's hash so you can confirm you have the file we built. What Defender reacts to is not something it found inside the file: Windows gives new files from small publishers a low reputation score because it has not seen them on many machines yet, and its machine-learning filter sometimes rounds that up to “might be a threat”, usually under a generic name like Wacatac. It tends to lift as more people install the same build, and we submit every flag to Microsoft for review. If it happens to you: check the hash, then allow the file in Windows Security → Protection history — step by step here. Never switch your antivirus off for us; we will never ask you to. Every release is already code-signed by Mailroom-LTD; what clears these flags for good is reputation, which each build earns as more people install it — and we speed that up by submitting every flag to Microsoft.
No. Mailroom reads the envelope — sender, size, date, and attachment names, types and sizes. Never the message body, never the file contents. An attachment’s file name is treated as private data: it is used on your device and never leaves it. All mail processing happens on your device — we never see your messages, senders, subjects or folder names. The KeepSafeTM engine triages using message metadata and product logic rather than sending your mailbox to a server to be read. The full details are in the privacy notice.
It's a focused launch, not a limitation. We'd rather get one provider genuinely right than spread thin across several. Support for more providers is planned — see the roadmap above.
The trial gives you 14 days, or 500 MB of deletion, whichever comes first. After that you can still open Mailroom and view your last scan — nothing you've already seen disappears. To run a new scan or clean up more mail, you buy a one-time yearly licence. There's no reduced free tier, and the choice to continue is entirely yours. Worth the comparison: Yahoo’s cheapest published storage add-on is $1.99 a month — about $24 a year, every year. A Mailroom licence is £6.99 once for the year, or £9.99 for three mailboxes.* Yahoo pricing as published by Yahoo in July 2026, on its storage subscriptions page. Yahoo sets its own prices and may change them at any time; Mailroom is independent and not affiliated with Yahoo. Yahoo’s figure is listed in US dollars and Mailroom’s in pounds — the two are shown side by side, not converted.
Your licence activates on the machine you bought it on. If you move to a new device, email support and we will move it across for you — there is no repurchase. Your scan data lives locally on each device, so a fresh machine starts with a new scan.
You can open the app and review your last scan offline — your results are stored on your device. Starting a new scan or a cleanup needs an internet connection, both to reach your mailbox and to confirm your licence. If you're offline, Mailroom simply pauses new work and tells you why, rather than guessing.
No. Mailroom is a one-time yearly licence, purchased per account count. Nothing renews automatically and there's no recurring billing. When the year is up, you decide whether to renew.
Mailroom relies on provider-supported access pathways that your email provider makes available to you. You're generally entitled to access and manage your own mailbox, but providers may change how those pathways work over time. If that happens, some Mailroom functionality could be temporarily — or in some cases longer-term — disrupted until compatibility is restored. We keep this transparent in our terms.
