DNS lookup and bulk check

Use the DNS Lookup tool to read live DMARC, SPF, DKIM, MTA-STS, BIMI, MX and TLS-RPT records for any domain. Check a single record, run a Quick Check of all types, bulk-check a whole portfolio with CSV export, compare two domains, and re-run from history.

Managing domains and groups

Run a whole domain estate from the Domains page: search and status filters, bulk import, organising domains into groups, rechecking records, reading the D/S/K/M/B service badges, and deleting domains safely.

Hosted SPF

How hosted SPF works, why the 10-DNS-lookup limit breaks records, and step-by-step setup, sender merging, ~all vs -all, verification and troubleshooting.

Troubleshooting

Fix Pending domains, non-resolving CNAMEs, missing DMARC reports, SPF PermError, DKIM alignment, MTA-STS Activating, BIMI logo issues, and forwarding breakage.

DNS record reference

A complete reference of every DNS record DMARC Engine publishes or checks: DMARC TXT, SPF TXT, DKIM, MTA-STS, TLS-RPT and BIMI, with exact hostnames, examples and how each is delegated by CNAME.

Migrating from another DMARC provider

Switching DMARC providers feels riskier than it is, because the thing you are moving is not your mail, it is a set of DNS records and a reporting destination.

Adding your first domain

Add a domain to DMARC Engine, verify ownership, and understand your hosting slug, domain status, and the DMARC/SPF/DKIM/MTA-STS/BIMI tiles.

How SPF flattening works

SPF records break when they need more than ten DNS lookups to evaluate, and the failure often arrives without you changing a thing. This guide explains the ten-lookup limit, walks through the SPF Flattening tab in DMARC Engine click by click, shows how to read the lookup counter, the Include Tree and the flattened IP list, and explains how hosted SPF keeps your record under the limit automatically with a single include.

Delegating your DNS with CNAMEs

How CNAME delegation works in DMARC Engine: the exact records for DMARC, SPF, DKIM, MTA-STS and BIMI, host-by-host setup, and how to verify propagation.
