Server instructions

MailSentry verifies email addresses in real time (syntax, MX, live SMTP handshake). verify_email costs 1 credit per address and returns result "safe" | "risky" | "invalid". Treat "risky" (catch-all domains) as sendable but unconfirmed. All tools require an API key sent as an "Authorization: Bearer ms_..." header; keys are created at https://mailsentry.pro/dashboard/settings. Machine-readable REST docs: https://mailsentry.pro/llms.txt
