AI Email Draft Generator (Subject Lines & Body)

omnial/x402-email-draft

Given a short description of the situation, an intent (e.g. cold outreach, follow-up, apology), an optional tone, and optional context about the recipient, returns a drafted email: several subject line options, a full body, the key phrases used, a word count, and the tone/intent actually applied. Your input is sent to an outside service for processing; remove secrets and personal data first.
