email-engineering

v0.3.5

Email-engineering team — 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), inbox categorization (Gmail tabs, Outlook Focused Inbox, Apple Mail), 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). skills, a knowledge bank, best-practices, templates, commands, a scenarios bank, a stdlib auth-record linter, and an advisory hook. Seams: strategy -> marketing-operations, infra -> backend-engineering, DNS -> cloud plugins, security -> security-engineering. Requires ravenclaude-core@>=0.7.0.

Included Skills5

bounce-complaint-suppressionskills/bounce-complaint-suppression/SKILL.md

Close the email feedback loop — classify hard vs soft bounces and spam complaints, enforce a suppression check before every send, and reconcile the ESP's suppression list with your own so you never re-send to a bad address. Reach for this when the user says "we keep emailing bounced addresses", "handle complaints", or "build a suppression list". Used by `email-sending-engineer` (primary).

deliverability-auditskills/deliverability-audit/SKILL.md

Diagnose why mail is landing in spam (or pre-flight a domain before a big send) by traversing the deliverability triage tree — authentication, DMARC alignment, reputation/warm-up, list hygiene, content, and bulk-sender compliance — then return the specific failing layer, the fix, and how to confirm it from postmaster/RUA signals. Reach for this when the user says "why are we going to spam?", "audit our deliverability", or "are we Gmail/Yahoo compliant?". Used by `email-deliverability-architect` (primary).

email-authentication-setupskills/email-authentication-setup/SKILL.md

Stand up SPF, DKIM, and DMARC (and optionally BIMI) for a sending domain and reach enforcement safely. Traverse the authentication decision tree (authenticate -> align -> enforce), emit the exact DNS records, and stage a p=none -> quarantine -> reject rollout gated on aggregate-report evidence. Reach for this when the user says "set up SPF/DKIM/DMARC", "get to DMARC enforcement", or "pass Gmail's sender rules". Used by `email-deliverability-architect` (primary).

email-template-engineeringskills/email-template-engineering/SKILL.md

Build responsive HTML email templates that render across clients (Outlook/Word engine, Gmail clipping, Apple Mail dark mode) using MJML or table-based HTML, with a plain-text part, accessible markup, and the client-quirk guards. Reach for this when the user says "build a <type> email", "my email looks broken in Outlook", or "make this email responsive / dark-mode safe". Used by `email-sending-engineer` (primary).

transactional-email-integrationskills/transactional-email-integration/SKILL.md

Integrate an Email Service Provider (SES, SendGrid, Postmark, Resend, Mailgun) for transactional sending with idempotent sends, signature-verified and idempotent webhook event handling (delivered/bounce/complaint/open), and retry/rate-limit discipline. Reach for this when the user says "wire up <ESP>", "send receipts/password resets", or "handle delivery webhooks". Used by `email-sending-engineer` (primary).
