What problem does it solve? Building email features involves many failure points: messages landing in spam, missing DNS authentication, legal compliance violations, duplicate sends, and unhandled bounces. This Skill provides structured guidance covering the full email lifecycle so your emails reach inboxes and meet legal requirements. ## Core Features & Use Cases - Deliverability & Authentication: Set up SPF, DKIM, and DMARC records, warm up sending IPs, and diagnose why emails go to spam. - Transactional & Marketing Guidance: Design password resets, OTPs, order confirmations, and newsletters with correct subject lines, mobile-first layouts, and consent flows. - Production Reliability: Implement idempotency keys, exponential backoff retries, webhook signature verification, and suppression list management. - Use Case: You are adding a password reset flow to a SaaS app. The Skill routes you to the transactional email guide for content design, the deliverability guide for DNS setup, and the sending reliability guide for idempotent retry logic. ## Quick Start Ask the agent to help you set up email authentication and plan the transactional emails your app needs, and it will route to the right resource.
