Understand your DMARC policy at a glance
This checker retrieves your public DMARC TXT record and explains what each tag means so you can improve deliverability and trust.
How the DMARC checker works
We look up the _dmarc TXT record for your domain, parse each tag, and summarize policy strength, alignment, and reporting settings.
Why check DMARC?
- Detect missing or invalid tags before they impact deliverability.
- See how strict your policy is for subdomains and alignment.
- Confirm reporting addresses so you receive feedback from receivers.
