Is your domain ready for cold email?
Find out in ten seconds.
Check the records behind your email setup. Get the pass/fail summary first, then practical steps to fix what’s missing.
Up to 10 checks per browser per day. DNS lookups use Google, with Cloudflare as a fallback.
Start with the records behind your email.
Your domain’s DNS tells receiving servers which mail systems can act for you. MX records route incoming email. SPF names authorised sending services. DKIM publishes a key used to check message signatures, while DMARC tells receivers how to handle messages that do not align with your domain. Missing or conflicting records can undermine a campaign before anyone reads the copy.
This tool checks public DNS through Google, with Cloudflare as a fallback. It looks for one SPF policy, a DMARC enforcement setting and DKIM entries at common Google and Microsoft selectors. An unconfirmed DKIM result does not mean signing is absent: your provider may use another selector. The website A-record check is informational.
Use the fix notes with your email provider’s instructions. Consolidate duplicate SPF records, verify legitimate senders before tightening DMARC, and enable DKIM in the provider’s admin console. These are DNS checks, not an inbox-placement test. Keep cold outreach on separate sending domains rather than your business’s primary domain.
