The Email DNS Checker looks up MX, SPF, DKIM, and DMARC records for a domain and scores basic configuration. DKIM depends on the correct selector — absence for tested selectors is reported as NOT VERIFIED, not as a hard failure.
1
Enter a public domain name.
2
Optionally set a DKIM selector, or leave blank to try common presets.
3
Click Check Email DNS and review the score plus each section.
DKIM selectors vary by provider (e.g. google, selector1). Leave blank to probe common names.
Multiple SPF records are invalid — keep a single v=spf1 TXT.
p=none DMARC is monitoring only; quarantine/reject enforce policy.
