Email-engineering team — 2 agents (email-deliverability-architect, email-sending-engineer) for getting legitimate mail to the inbox: domain authentication (SPF, DKIM, DMARC alignment + a staged p=none -> quarantine -> reject rollout, BIMI), transport security (MTA-STS RFC 8461 + TLS-RPT RFC 8460), deliverability (subdomain stream separation, domain/IP warm-up, reputation, Gmail/Yahoo bulk-sender rules), ESP integration (SES/SendGrid/Postmark/Resend) with idempotent sends + verified webhook handling, MJML templates, and the feedback loop (bounce/complaint classification, ARF, suppression lists, one-click unsubscribe per RFC 8058). 5 skills, a 4-doc knowledge bank (Mermaid auth + diagnosis trees + dated 2026 ESP map + transport security), 9 best-practices, 3 templates, 4 commands, a scenarios bank, a stdlib auth-record linter, and 1 advisory hook. Seams: strategy -> marketing-operations, infra -> backend-engineering, DNS -> cloud plugins, security -> security-engineering. Requires ravenclaude-core@>=0.7.0.
