Summary
Connects Claude to mailX's email deliverability and DNS infrastructure APIs. Exposes operations to check SPF, DKIM, DMARC, and BIMI records, run blacklist lookups, test SMTP and IMAP connections, and perform DNS queries (A, MX, TXT, CNAME, PTR records). Also generates email authentication records like SPF and DMARC policies. Useful when debugging why emails land in spam, auditing domain configurations across multiple clients, or troubleshooting mail server connectivity. All checks run against live DNS in real time. The underlying service is free with no signup required, making it straightforward for agents to diagnose deliverability issues on the fly without credential management.
