DMARCFlow

DMARCFlow helps you find out who is sending email in your name and whether your domain is protected against spoofing and phishing. Run free DNS checks in a few taps, understand the results without being an email expert, and monitor every domain you own from one place. FREE CHECKER TOOLS, NO ACCOUNT REQUIRED - DMARC Checker: validate your DMARC policy, alignment mode, subdomain policy and reporting setup - SPF Checker: inspect your SPF record and DNS lookup count before you hit the limit - DKIM Checker: verify that your DKIM signing key for a selector is published and valid - BIMI Checker: check whether your brand indicator is set up correctly Every check comes back as a score from 0 to 10 with a rating from Excellent to Critical, a clear list of issues and warnings, and a plain-language explanation of what each finding means and what to fix. MORE FREE TOOLS - Deliverability Check: MX, SPF, DKIM and DMARC in one check, with a single score for your domain - MX Checker: find your mail servers, see whether they are reachable and redundant, and spot null MX or missing TLSA records - Blacklist Check: test a domain or IP address against well-known spam blacklists and see exactly where it is listed - Header Analyser: paste the headers of an email to trace its delivery path and authentication results GET A DETAILED PDF REPORT Enter your email address and we send you a PDF with detailed findings and recommendations for your domain. No spam, no account required.
