Stop deciding what to delete
Say what to keep

A Mac app that empties an overloaded mailbox without losing what matters. Connect as many mailboxes as you like, set one rule for what's worth keeping, and see the entire list before a single message moves.

Try the toggles — this is genuinely how the app decides

How it works

Four steps, one of which changes anything

The order matters. Nothing is destroyed until you have seen exactly what would be.

01

Connect your mailboxes

Add as many as you like — Gmail, iCloud, Outlook, Fastmail, IONOS or any IMAP server. Or import what is already in Apple Mail.

02

Say what to keep

Flagged mail, unread mail, drafts, or any combination. The app describes your rule in plain English before it runs.

03

Scan, and change nothing

A read-only pass producing two lists. Folders are opened read-only, so a scan cannot even mark mail as read.

04

Review, then clean up

Adjust anything you disagree with, then delete — to Trash by default, so it stays recoverable.

The whole app

Two lists. You get the final say on every row.

Ticked is kept, unticked is deleted — on both tabs. Rescue anything from the delete list, or untick something on the keep list to bin it after all.

19 seconds, real app, sample mailbox — nothing here is real mail

Safety

Built by someone afraid of it

This app deletes mail in bulk. Every decision assumed that getting it wrong would be unforgivable.

✓ Read-only

Scanning genuinely changes nothing

Every folder is opened in read-only mode, so the server will not even mark mail as seen.

✓ Recoverable

Trash, not oblivion

Deletions move to your Trash folder and stay recoverable. Permanent deletion is a separate, deliberate choice.

✓ Narrow by default

Your inbox only

Subfolders, Sent, Drafts, Archive, Trash and Junk are left alone unless you explicitly ask otherwise.

! Honest

It tells you when it is unsure

If your provider reports flags in a way the app does not recognise, it says so and tells you not to clean up yet.

✓ Private

Nothing from your email is stored

It reads sender, subject and date to sort your mailbox, and keeps none of it. No message content ever leaves your Mac.

✓ Local

Passwords stay in your keychain

Encrypted by macOS itself. The only connection made is to your own mail provider — there is no server of ours in between.

✓ No account

Nothing to sign up for

No licence key, no registration. Download it and it works.

✓ Manual

Nothing runs on its own

No schedule, no background job. Every scan and every deletion happens because you pressed a button.

Features

What you get

Import from Apple Mail

Pulls addresses, servers and ports of mailboxes already on your Mac.

Block a sender

Their mail always goes — and goes to Junk, so your provider's filter learns them.

Select all, or one by one

A tick in the column header covers the whole list, not just the visible rows.

Sign in with Google

Or use an app password. Both work, and you can switch between them.

Multiple mailboxes

Each cleaned separately — deliberately no "clean everything" button.

Signed and notarised

Approved by Apple, so it opens without security warnings.

Get it

Free. Not a trial.

No licence key, no upgrade prompt, nothing to pay later. Leave your email and we will send the download link and a short guide to setting it up.

Questions

Fair things to ask

Can it delete something I wanted to keep?

You see the full deletion list before anything happens, and you can rescue any message from it with one tick. Deletions go to Trash by default, so they are recoverable even then.

Does it read the contents of my emails?

No. It asks your provider for the sender, subject, date and flags of each message — the same details your mail app shows in a list — and never downloads the body of anything. Those details sort your mailbox on screen and are then discarded; none of it is stored, logged or sent anywhere.

Can anyone at We Are One Apps see my mail?

No. The app talks directly to your mail provider from your own Mac — there is no server of ours anywhere in the chain, so there is nothing for us to look at even if we wanted to.

What do you keep about me?

Only the email address you give us on this page, used to send your download link, app updates and news about other useful apps from We Are One Apps. Never shared or sold, and you can unsubscribe from any email. Nothing from inside your mailbox is collected or transmitted.

Why does it need an app password?

Nearly every provider now refuses ordinary account passwords from third-party apps. An app password is generated by you, only works for mail, and can be revoked whenever you like. For Gmail you can sign in with Google instead.

Does it work with my provider?

Any IMAP mailbox. Gmail, iCloud, Outlook, Yahoo, Fastmail and IONOS have ready-made settings; anything else takes a host and port.

Intel Macs or Windows?

Apple Silicon only for now. If there is demand for an Intel build, that is straightforward to add — email info@weareoneapps.com and say so.
