Email Deliverability Audit API

Gives Claude a quick way to check if your email setup will actually land in inboxes. It audits SPF, DKIM, DMARC, and MX records for any domain and returns a 0-100 deliverability score. The server connects via SSE to a remote API at klymax402.com. You'd use this when debugging why emails are hitting spam folders, during domain migrations, or as part of automated checks before launching a campaign. The scoring gives you a single number to track rather than manually parsing DNS records and trying to figure out what's misconfigured.
