Hi everyone. I'm James Nerlinger, independent developer/owner of Deep Dark Abyss Productions. I built MailKP because I had a problem: years of newsletter signups, store promotions, and general junk had buried my inbox to the point where finding real email was a task. During development and testing I ended up clearing around 250,000 emails from my own accounts across Gmail, Yahoo, iCloud, and a private hosted server.
The app connects directly to your email server via IMAP and permanently deletes junk in bulk. It uses a whitelist-first approach, so you protect your contacts, your bank, your doctor, whoever matters, and then let it loose on the rest. It processes thousands of emails in minutes. It will even build your white-list straight from your Contacts to help get it started.
A few things that set it apart: everything runs locally on your Mac. No cloud, no data collection, nothing leaves your machine. Most of the competing tools either require cloud access or charge a monthly subscription. MailKP is free to use with optional one-time supporter tiers ($2.99 / $4.99 / $9.99) if you want to support development (which would be greatly appreciated). No paywall, no locked features.
It works with Gmail, Outlook, Yahoo, iCloud, and any IMAP server. You can import your contacts to instantly protect them, analyze your sent mail to find people you actually correspond with, and build up a junk database that gets smarter over time. Once your database is built, the Quick Clean mode makes weekly maintenance pretty painless.
Currently on v1.6 after a few bug fixes and reliability improvements since launch.

Happy to answer questions and always open to suggestions, especially where it improves the app's functionality.
