DMARC Checker

🛡️ 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 3. get a dmarc check tool verdict with warnings and concrete fixes ✨ Key features at a glance ✓ instant dmarc lookup and parsing for any domain ✓ a raw-string mode for a dmarc syntax check with no DNS ✓ an analyzer that explains every tag in your dmarc record ✓ a strength rating and a one-click view of the published record 🧪 Two ways to run a check You can check a live domain or validate a record you have not published yet. Both paths share the same engine, so the record check reads the same whether it comes from DNS or from text you paste. There is nothing to install beyond the extension itself, and the verdict appears the moment the lookup returns or the parser finishes. 1️⃣ validate a domain — a DNS dmarc lookup pulls the live record 2️⃣ analyze a record string — a dmarc syntax check with no lookup 3️⃣ read the verdict — strength rated none, weak, moderate or strong ✅ Syntax and policy analysis The analyzer reviews each tag in your record and explains it in context. A careful dmarc syntax check catches typos, invalid values and risky settings before they hurt deliverability. Every check dmarc record run ends with a short, readable report you can act on right away. • v and p — protocol version and the main dmarc policy • sp, adkim and aspf — subdomain policy and alignment • pct, rua, ruf and fo — sampling and where reports are sent ⚠️ Warnings you can act on A good check is not only about reading a record, it is about spotting weak spots. The tool highlights common problems so your policy actually protects the domain. - p set to none with no reporting in place - a missing rua address, so aggregate reports go nowhere - pct below 100 that quietly weakens the policy - a dmarc record check that finds more than one record on the host 👥 Who needs it ➤ IT and DevOps — a fast dmarc check tool for every mail domain ➤ Security teams — audit a policy against spoofing and phishing ➤ Developers — verify a record for new apps and services ➤ Email and marketing — a clean email dmarc check before each campaign 📈 Why DMARC matters DMARC works together with SPF and DKIM to confirm who really sent a message. A correct policy with p reject blocks unauthorized mail sent from your domain and protects your brand. Since 2024, Gmail and Yahoo ask bulk senders for a valid record, so a regular check is now part of staying in the inbox instead of the spam folder. The _dmarc TXT host is where the record lives, and this tool reads and explains it for you. ❓ dmarc lookup, dmarc test and check — what is the difference A dmarc lookup fetches the raw record from DNS. A dmarc test validates that record and its policy. This dmarc checker does both: a single record check gives you the lookup, the full analysis, and a clear next step in one place. 🚀 How to use it ➸ open the extension on any tab in your browser ➸ enter a domain and run the dmarc checker, or paste a record string ➸ review the tags, read the warnings, and fix the weak spots ❓ Do I need an account No. This dmarc record checker runs fully in your browser and returns instant results, whether you need a one-off dmarc email check or a daily routine across many domains. Bookmark it and keep the tool one click away whenever you touch DNS. 🔒 Privacy first This dmarc checker collects no personal data and shows no ads. DNS queries run through public resolvers, and nothing about your domains is stored in your browser or shared. No tracking, no sign up, no noise. Run a check now, validate your record, and keep your domain safe from spoofing with a policy you can trust.
