Why DNS Authentication is Critical
Major email providers like Gmail, Yahoo, and Outlook enforce strict SPF, DKIM, and DMARC authentication policies. Unauthenticated emails are frequently routed to the spam folder or rejected entirely.
Required DNS Records
Add the following authentication records at your DNS host (Cloudflare, GoDaddy, Namecheap, Route53):
- SPF (TXT):
v=spf1 include:spf.mtasv.net ~all(when using Postmark) or your mail provider's SPF include record. - DKIM (CNAME or TXT): Add the DKIM public key records generated by your email delivery provider (such as Postmark or your mail provider).
- DMARC (TXT):
v=DMARC1; p=none; rua=mailto:dmarc-reports@yourdomain.comat_dmarc.yourdomain.comto monitor deliverability.
