Email authentication checks API

Email authentication checks

Check a domain’s or IP’s email authentication DNS records: reverse DNS, MX, SPF, DMARC, MTA-STS, TLS-RPT and BIMI. The API calls them deliverability checks (/api/v1/deliverability). Unlike blocklist and certificate checks, an email authentication check runs while you wait and the response holds the result. Each check costs 1 credit, and a check that errors is refunded.
