Unsubscribe.
Your missing medieval newsletter unsubscriber.

Because why not? Modern software is boring, everything looks the same. Let's have some whimsy!

No, nothing to do with your Netflix bill. Unsubscribe deals with mailing lists: the newsletters, promotions and digests that you subscribe to without even knowing and then they pile up in your inbox. It finds them, unsubscribes you with a single click and clears out what they already sent. You can choose which newsletters from a single domain you would rather keep or not.

Never. Everything goes to Mail's Trash, where it stays as long as your Trash settings say. If a delete caught something you wanted, drag it back out.

In Mail app mode, Unsubscribe reads the emails Apple Mail stores in ~/Library/Mail, and macOS only allows that with Full Disk Access. Add Unsubscribe in System Settings › Privacy & Security › Full Disk Access and relaunch. Mail servers mode doesn't need it.

Mail app mode reads the emails Apple Mail keeps on your Mac and asks Mail to move the unwanted ones to the Trash. Apple requires every App Store app to run in a sandbox that forbids both: reading another app's data and driving another app. There is no way to do what Unsubscribe does from inside that sandbox.

Outside the App Store, Unsubscribe is signed with Apple Developer ID, built with the hardened runtime and notarized by Apple, which scans every release for malware before macOS will even open it. That is the same bar every other app on your Mac has to clear.

• Mail app is the default mode and best for everyday cleanup. No passwords are involved, it works offline, and rescans in seconds. Some providers like Outlook.com and Hotmail work only here. It needs the least setup. The only trade-off is that bulk delete is a bit slower.
• Mail servers connects to your IMAP accounts directly, deletes much faster and reaches mail that Mail never downloaded, like archived Gmail. Each account needs a password (an app-specific one for Gmail, iCloud and Yahoo). Work or school accounts may block IMAP. Most people, me included, do fine in Mail app mode and never need to switch. Reach for this one when a delete of thousands of emails is crawling, or when Mail only holds part of your mailbox.

No. Unsubscribe reads Mail's files or talks to your mail servers directly. There is no account, no sync and no analytics. The only network calls of its own are the license check and opening the newsletters' unsubscribe pages in your browser.

We can't force anyone to stop. However, Unsubscribe remembers when you left and keeps track of resubscriptions. A red ↩ next to a sender's name means the address has emailed you since. Mark it as junk in Mail, or delete by sender in Unsubscribe to keep the inbox clean.

Use Mail app mode. It works through Apple Mail, so it covers every account Mail can read: POP3, Exchange, Outlook.com, Hotmail, iCloud and plain IMAP alike. Unsubscribe never talks to those servers itself; it reads what Mail already downloaded and asks Mail to move things to the Trash.

Mail servers mode is IMAP only on purpose. POP3 has no Trash folder, so a delete there would be final rather than recoverable, and Unsubscribe never deletes anything for good. Exchange needs a Microsoft sign-in flow rather than a password. When you import your accounts from Mail into Mail servers mode, POP3 and Exchange accounts are skipped and a note tells you how many; they keep working in Mail app mode.

Try it free on your first 7 senders, with no time limit. If you like it, the license is bought once and works on up to 3 Macs. It will never become a subscription.

Yes. A theme is a .unsubtheme package with assets. Copy one of the built-in ones, change what you like and double-click it to install.

Yes. Settings › Language › Export Template saves a Markdown file listing every text in the app. Fill in the Translation column and import it. English, German, Spanish, French, Polish, Brazilian Portuguese and Ukrainian are built in.
