As a server admin, I don’t know much about how to build a big list or write compelling copy to boost conversion rates, but I do know that having the right DNS records is key to successful email delivery.

The 3 DNS Records you must know for good email delivery are:

  • Reverse DNS (PTR)
  • SPF (Sender Policy Framework)
  • DKIM (DomainKeys Identified Mail)

These are the 3 DNS records you must have correct for sending email reliably.   Of course, you need an MX record if you want to receive email, but that’s another topic.
