DMARC Records Tools
Stop your DMARC reports from silently disappearing. Verify External Destination Verification (EDV) records, validate complex mailto: URIs, and ensure your third-party SaaS providers are legally authorized to receive your data.
If you send DMARC reports (RUA/RUF) to an external domain (e.g., a third-party service), that service MUST explicitly authorize your domain via an EDV DNS record. If they don't, mail servers will silently drop your reports. Verify your setup here.
Publishing rua=mailto: is not enough. You must ensure the destination is syntactically valid, appropriately sized, and legally authorized to receive your data.
mailto: prefix or using semicolons instead of commas to separate multiple email addresses. We rigorously check your URI formatting.!10m for 10 Megabytes). We extract and display these size modifiers so you know your inbox won't be flooded.Your feedback has been submitted successfully. We appreciate your help in improving our tools.
