The five records that decide your inbox placement

Each one is a checkpoint between your email and your customer's inbox. Miss one, and the message gets filtered.

MX Records

MX records tell the world where to deliver email for your domain. Get them wrong and messages never arrive, no matter how cheap or premium your hosting is. This is the foundation everything else sits on.

SPF Record

Lists which servers are allowed to send email as you. Misconfigured SPF is the single most common reason cheap email setups land in spam.

DKIM Record

A cryptographic signature that proves an email genuinely came from you and was not tampered with in transit.

DMARC Record

Your policy for what happens when a message fails SPF or DKIM. Without it, spoofers can impersonate your domain.

Domain DNS

Confirms your domain resolves correctly. Broken DNS quietly undermines every deliverability signal above it.

Why authentication decides deliverability

Mailbox providers trust authenticated senders. Without the right records, even legitimate email gets treated as suspicious.
