Records We Generate
SPF Record
Authorizes which servers can send email for your domain.
DKIM Setup
Instructions for adding your cryptographic signature.
DMARC Record
Defines how to handle authentication failures.
MX Records
Points incoming email to your provider's servers.
Common DNS Providers
These instructions work with any DNS provider including Cloudflare, GoDaddy, Namecheap, Route 53, Google Domains, Porkbun, and others. The process is similar across providers - just copy the record type, name, and value into your DNS management panel.
DNS Propagation Time
After adding records, changes can take up to 48 hours to propagate globally. However, most changes are visible within 1-4 hours. Use our Domain Health Checker to verify your records are live.
Important Notes
- SPF records - You can only have one SPF record per domain
- DKIM keys - Must be obtained from your email provider's admin console
- DMARC policy - Start with "none" and gradually strengthen to "reject"
- MX priority - Lower numbers have higher priority
Three rules. Memorize them.
SPF, then DKIM, then DMARC.
In that order. Each builds on the last. Skip DKIM and Outlook quietly junks half your mail.
Use DMARC quarantine, not none.
DMARC=none does nothing. Set p=quarantine + rua report email. Catch spoofing in 24h.
Re-check after every DNS change.
DNS propagates inconsistently. Verify all records hit before you trust the new config.
