SPF, DKIM & DMARC Generator
Create SPF and DMARC DNS records, plus the correct DKIM hostname and record format for your email provider. Copy the values into DNS, then verify the live setup with the checker.
Your sending provider creates the matching private key. Never generate or paste a private key here.
Generate first, then verify
SPF and DMARC records can be generated from your domain and provider details. DKIM is different: your email provider must create the private signing key, then gives you the matching public key to publish in DNS. This generator formats that public record without ever handling a private key.
Publish the records in your DNS provider, allow DNS to propagate, then use the SPF, DKIM & DMARC Checker to confirm receivers can see the records you intended to publish. Keep one SPF record per domain and begin DMARC at p=none if you have not yet monitored alignment failures.
FollowClose Rainmaker verifies your sending domain and handles the operational parts of reliable follow-up delivery, including DKIM and reply tracking.
