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.
Enter a public domain name.
Optionally set a DKIM selector, or leave blank to try common presets.
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.
