skill:email-gateway - Multi-Provider Email Gateway

Version: 1.0.0

Purpose

Generate production-ready email sending integrations for Cloudflare Workers and Node.js applications. This skill produces a unified email interface that abstracts provider-specific APIs (Resend, SendGrid, Mailgun, SMTP2Go), includes template rendering, error handling with retry logic, and delivery tracking via webhooks. Use this skill when a project needs transactional or notification email capabilities with provider flexibility.
