Free email authentication tools
The same checks the paid product runs continuously, free for one-off use. No signup, no email gate. Results in plain English with the exact fix.
DMARC checker
Reads a domain's DMARC record live and explains every tag (policy, reporting, alignment) with the exact fix for anything broken.
DMARC record generator
Answer two questions (who sends your email and how strict to be) and get a correct starting record with every tag explained.
SPF checker
Counts your DNS lookups against the 10-lookup limit the way receivers do, with a visual tree of every nested include.
DKIM checker
Validates a DKIM key by selector: existence, key length, revocation. Don't know the selector? We probe the common ones.
DMARC report analyzer
Drop in one of those XML report attachments (.zip, .xml.gz, .xml) and read it as a table: who sent as your domain and what passed.
Checking once tells you today. DMARCPath runs these checks continuously, reads your DMARC reports, and alerts you when something breaks. One domain free forever. Start monitoring →
