What it does.

01 02 03

01Stops the spam your inbox lets through

Catch what your built-in filter misses

From header anomalies and brand impersonation to URL spoofing, BEC (CEO fraud), and P2P payment scams — Junkless identifies structural spam patterns the built-in filter misses, using built-in detection rules.

Mark a single message as spam, and Junkless flags similar structural patterns automatically.

01Header anomaly detection (SPF/DKIM/DMARC mismatch)
02Brand impersonation detection (banks, Amazon, PayPal, etc.)
03URL spoofing detection (display text vs. link mismatch)
04BEC and CEO-fraud pattern detection
05P2P payment abuse detection (PayPal, etc.)

DETECTION: Rule-based + SimilarityAI: Not usedFALSE POSITIVE FIX: Trust sender

02Local-first by design

Your email never leaves your Mac

Email content and IMAP credentials stay on your device. No cloud AI, no server, no API calls — every classification happens locally.

If your email carries contracts and client data, the most reliable safety is data that doesn't leave your Mac.

01Credentials encrypted locally via OS-level encryption
02Raw email content is not stored — only derived filtering features are kept locally
03Learned patterns kept in Junkless's protected storage
04Network: only your IMAP server and Mac App Store services

NETWORK: Your IMAP onlyANALYTICS: NoneTRACKERS: None

03Transparent detection

Confidence scores on every flagged message

Each flagged message displays a confidence score so you can quickly review detections. Rule-based logic you can understand — no black box.

Transparent scoring, not a black box. The clarity that matters most to engineers and professionals.

01Confidence score badge on each message
02Built-in detection rules plus your learned patterns
03Trust sender to whitelist legitimate senders
04Save suspicious emails as `.eml` files for IT review or phishing reports

AUDIENCE

Who it's for.

─── A GOOD FIT IF

01Independent professionals (consultants, freelancers, lawyers, accountants) running their own email domain through a Mac mail client
02Anyone manually clearing missed spam from their inbox every week
03Email users who refuse to send their content or credentials to a cloud service (contracts and client data live in their inbox)
04Anyone looking for a standalone, one-time-purchase spam filter that works alongside their existing mail client

─── NOT A GOOD FIT IF

-Anyone expecting a zero-configuration filter (IMAP setup is required)
-Users wanting the latest machine-learning AI detection (Junkless uses rules + similarity, not AI)
-Windows or iOS users (Mac only)
-Users expecting fully automatic detection from day one (you'll mark a few spam messages first)

FAQ

How does Junkless decide whether an email is spam?

Junkless checks built-in rules for SPF / DKIM / DMARC mismatches, brand impersonation, URL spoofing, and invoice, payment, or account-warning language. It also compares messages against patterns you have marked as spam, all locally on your Mac.

Will my email be sent anywhere?

No. Junkless connects only to your IMAP server (Gmail, iCloud, Fastmail, etc.) and Apple's Mac App Store services. Nothing else.

Which mail providers are supported?

Any IMAP server: Gmail, iCloud, Fastmail, Outlook, Proton (via Bridge), and custom domains. Setup guides are in the Help page.

Is there a Windows or iOS version?

No. Junkless is Mac only. There are no plans for other platforms at this time.

Do I need to mark spam manually?

Yes. Junkless learns from your spam marks. Mark a few obvious spam emails to start, and Junkless catches similar messages automatically.

How is this different from other spam filters?

Junkless combines three things in one app: (1) a standalone client (not a plugin to your mail app), (2) fully local processing (no email content or credentials in the cloud), and (3) transparent, rule-based detection with confidence scores. Plus it's a one-time purchase, not a subscription.

What if I uninstall Junkless?

All Junkless data lives on your Mac. To remove it, first delete your accounts in Junkless, then uninstall the app. If any local app data remains, you can remove Junkless's data folder from macOS storage manually.
