Make the report useful
A receiving server reports an IP and its authentication results. DemiSignal puts those details together so you can investigate.
An unattributed IP remains unknown. A failing result alone does not tell you who sent the message.

Questions, answered
A one-off check of the email records published for your domain. No account or card is required. Ongoing checks, alerts, and DMARC report monitoring are paid.
A receiving mail server’s summary of messages sent as your domain. It includes sending IPs, message counts, authentication results, and how the receiver handled the messages. The free report analyzer reads one in your browser.
After you add your reporting address, the first report commonly arrives within 24 to 48 hours. Each receiving provider controls its own reporting schedule.
The free scan only needs a domain name. For ongoing monitoring, someone with DNS access must add the private reporting address to the rua tag in your DMARC record.
No. Adding the reporting address does not change enforcement. Collect a baseline at p=none, review legitimate senders, and fix problems before considering quarantine or reject.
Standard DMARC aggregate reports do not contain email bodies or recipient addresses. They contain summarized authentication results. Your reporting address uses a private token rather than your account or customer name.
Only messages in accepted reports that pass DMARC through aligned SPF or DKIM count. Failed or potentially spoofed traffic stays visible and does not use your message allowance.
Cancel in billing settings; monitoring continues until the end of your paid period. You can request a refund through our contact form or visit paddle.net. Refunds are governed by Paddle's Refund Policy.
