🛡️ DMARC Checker — look up, analyze and validate a DMARC record in one click

Email spoofing and phishing usually start where a domain has weak protection. This dmarc checker helps you look up, read and validate your record in seconds, so mailbox providers like Gmail, Outlook and Yahoo can trust messages from your domain. Run a quick check on any domain and see the full policy explained in plain language, without digging through raw DNS output by hand.

🔍 What the extension does

Type a domain or paste a record, press validate, and the tool shows the current policy with a clear verdict. The built-in dmarc analyzer breaks down every tag and tells you what it means, so each check run stops being guesswork and becomes a clear, repeatable routine for your whole team.

1. run a dmarc lookup for any domain in seconds

2. read the parsed record with clear, human notes
