Step-by-step instructions to actually fix the most common problems in an email setup — with ready-to-use DNS examples.

Set Up Authentication

SPF Create an SPF Record

An SPF record defines which servers may send email for your domain. Here is how to set one up correctly — including the pitfalls around the lookup limit.

DKIM Set Up DKIM

DKIM cryptographically signs your outgoing email. Here is how to generate the key pair, publish the public key and verify the result.

DMARC Set Up DMARC

DMARC ties SPF and DKIM into an enforceable rule. The road to p=reject runs through four phases — here is the full sequence.

Transport Security

TLS Set Up MTA-STS & TLS-RPT

MTA-STS enforces TLS for inbound email and closes the STARTTLS downgrade gap. Set up in three steps, plus reporting.

Branding & Reputation

BIMI Set Up a BIMI Logo

BIMI displays your brand logo next to your messages. It requires an enforced DMARC policy — here are all the steps.

BL Blacklist Delisting

A blacklisted IP or domain hits deliverability immediately. Here is how to find the cause and request delisting properly.

DNS Set Up Reverse DNS

Without correct reverse DNS, large providers reject connections. Three values have to agree — here is how to set them up.
