What we check
The signals that matter before your next send
Most deliverability issues show up in DNS and authentication long before reply rates collapse. Scan surfaces them in seconds.
SPF
Syntax, lookup count, and strict vs soft fail before you send.
DKIM
Selector discovery and record validation on your sending domain.
DMARC
Policy alignment, reporting tags, and common misconfigurations.
MX & mail routing
Whether your domain can receive mail and bounce handling signals.
Spamhaus DBL
Domain blocklist status via DNS — a common pre-send check.
Raw email headers
Paste a received message to inspect authentication results in context.
Who it's for
Built for teams that send at scale
Outbound & cold email teams
Validate DNS before rotating domains or scaling a new sending stack.
Agencies & consultants
Share scan links with clients and show authentication gaps in plain language.
Founders sending themselves
Quick sanity check when reply rates drop and you suspect a DNS misconfiguration.
From the field
What senders are saying
“Caught a DMARC none policy and broken SPF before we burned another domain. Saved us a week of guessing.”
“We send scan links to clients before onboarding — makes the audit conversation much easier.”
