Why are my emails landing in spam?

10 checks on your domain across authentication, transport and reputation. Pinpoints where your email deliverability is breaking.

No test email required. We only read public DNS records and (for MTA-STS only) one small HTTP file. No login, no scraping.

All scans

We only run public DNS checks and read one small MTA-STS file. No test email.

Authentication

  • SPF (`-all` vs `~all`)
  • DKIM selectors + key length
  • DMARC policy (`reject`/`quarantine`/`none`)
  • DMARC alignment (strict vs relaxed)

Transport

  • MTA-STS policy + mode
  • TLS-RPT
  • MX redundancy
  • Reverse DNS (PTR) on MX

Reputation

  • DNSBL (Spamhaus, Barracuda, SpamCop)
  • Domain age (RDAP)
