DemiSignal checks a domain's live DNS and grades its email authentication, so you can see why mail lands in spam or fails DMARC without leaving the conversation.
- check_domain: grades DMARC, SPF, DKIM (common selectors), MX, BIMI and MTA-STS. Returns each record, its status and the issues found, with a fix guide for every issue and a link to the full report.
- generate_spf_record: builds an SPF record from the services and servers that send your mail, and counts DNS lookups against SPF's limit of 10.
- generate_dmarc_record: builds a DMARC record and the host to publish it at, from your policy and report addresses.
No account or API key needed. The generators compute from your input only; nothing is looked up or stored. For ongoing monitoring and DMARC report analysis, connect the domain at demisignal.com.
