## Stop squinting at raw DMARC XML
Every domain sending email gets DMARC aggregate reports and SMTP TLS reports back from Google, Microsoft, Yahoo, and every other major mailbox provider — dense XML and JSON files nobody actually enjoys reading. Demarkable turns them into something you can actually understand at a glance.
Drag a report in — plain, zipped, or gzipped, it doesn't matter — and Demarkable shows you exactly what happened: which servers sent mail as your domain, whether SPF and DKIM passed *and aligned*, and in plain English, why a message failed if it did. Same story for SMTP TLS reports: which connections were encrypted under MTA-STS or DANE, which failed, and what actually went wrong (expired certificate, no STARTTLS support, a broken policy — spelled out, not just a result code).
## What it does
- Drag-and-drop (or ⌘O) import of DMARC aggregate reports and SMTP TLS reports
- Accepts `.xml`, `.json`, `.zip`, and `.gz` — auto-detects which report type it's looking at
- Per-source breakdown: sending IP, message volume, disposition, SPF/DKIM pass or fail
- Plain-English explanations for every failure — no more decoding raw result codes
- TLS report failure types explained: expired certs, missing STARTTLS, MTA-STS/DANE policy problems
- Local history of every report you've imported, with pass-rate at a glance — clear it anytime
- Native SwiftUI app built for the Mac — fast, no browser, no account, no subscription
## Who it's for
Anyone who owns or manages a domain's email — sysadmins, IT teams, email deliverability folks, indie founders running their own mail, or anyone who's ever opened a DMARC report and immediately closed it again.
## Privacy
Everything happens on your Mac. Reports are parsed locally and never leave your machine — Demarkable doesn't talk to the network at all. Only the parsed summary is kept in history (not copies of your original files), and you can clear it whenever you like.
