Domain Email Security Checklist

A checklist for improving domain email trust with SPF, DKIM, DMARC, and safer business workflows.

How to use it: Email trust affects newsletters, contact forms, business communication, and phishing resistance. Domain authentication is a practical security upgrade.

DNS records

SPF includes real senders. DKIM is enabled for mail provider. DMARC starts in monitoring mode. Records are checked after changes.

Workflow

Payment changes need secondary confirmation. Invoices are verified. Suspicious messages are reported. Staff know common phishing patterns.

Review

DMARC reports are checked. Old senders are removed. Newsletter sender is separated if needed. High-risk requests are escalated.

Recommended workflow

Inventory email senders.
Configure SPF and DKIM.
Add DMARC monitoring.
Train staff on payment-change scams.
Move toward stricter DMARC gradually.
