Know when your business email stops proving it's really yours.
KØNTACT watches the records that prove your domain's email identity and tells you when something changes — not everything, just what matters.
Runs in your browser. KØNTACT has no servers and never sees the domains you check — but your browser does send DNS queries to Cloudflare's and Google's public DNS resolvers to get the answers. Privacy notice · How it works

What this Check can and cannot tell you
KØNTACT evaluates your published email-authentication posture — SPF, DMARC, and DKIM as seen in public DNS. It does not prove inbox placement, message alignment, sender reputation, or blacklist status, and it cannot verify that every legitimate sender authenticates correctly. A first Check reports current state only — it has no yesterday to compare against.
One engine. Tiers are configuration, not construction.
The free Check is live today. Watch and MSP are coming — same findings, plus memory.
