DemiSignal Reviews & Product Details

DemiSignal combines email authentication checks with DMARC aggregate report monitoring. Its free one-off domain check examines SPF, DKIM, DMARC and MX records without requiring an account or card. Paid plans provide a private reporting address to add to the rua tag in a domain's DMARC record. Reports show sending IPs, message counts, authentication alignment and receiver disposition. Scheduled DNS checks and change alerts help track changes to email settings. Adding the reporting address does not change the domain's enforcement policy. Paid plans offer different domain and message allowances. Failed or potentially spoofed traffic remains visible and does not use the message allowance. Free tools include SPF and DMARC record generators and a DMARC report analyzer. The analyzer reads one aggregate report in the browser without uploading it; ongoing collection and monitoring require a paid plan.
