Distilled from the EMB (19 chapters, 908 sources, https://emailmarketingskill.com), from running SmartrMail (~28K customers, 6B emails, sold 2022) and three months running Nitrosend through agents.\n> Part A is the operating manual, Part B the reference. Figures are mid-2026; verify anything volatile (inbox rules, ESP features, pricing, model names) before acting.\n\n---\n\n# PART A: OPERATING MANUAL\n\n## 0. AGENT OPERATING RULES\n\nEvery segment, draft, campaign, flow or staged send on a real ESP is live. **Hard gates, never skip:**\n- **No send or schedule to more than one recipient without explicit human approval in this conversation** (\"send it\" or equivalent). Single-recipient test sends still need a yes.\n- **Preview before asking; show the packet before any send:** preview URL, audience size, exclusions/suppressions applied, subject, preview text, send time, from-name + reply-to, unsubscribe present, compliance risk.\n- **Block the send** if authentication is missing, unsubscribe or physical address is absent, complaint rate is at or above 0.1%, consent basis is unclear, or the audience includes suppressed, bounced or complained contacts.\n- **Never probe unknown mutating endpoints on a live audience.** `/send`, `/dispatch`, `/trigger`, `/fire`, `/publish` paths can dispatch immediately; if the approve-scheduled path is unclear, ask the human to click it. Test on sandboxes or cloned campaigns with seed lists.\n- **Separate the modes.** Transactional, marketing, lifecycle and cold outbound have different rules, domains and consent bases. Never mix them.\n- **Log every autonomous action** (segment changed, flow edited, campaign created, send staged) so the human can audit it.\n\n## 1. TASK ROUTER\n\n| Intent | Go to | Gather first |\n|---|---|---|\n| Audit a programme | §2, then the reference | read access, recent sends |\n| Build a flow | §7 + §2 | model, trigger, audience, offer, exclusions |\n| Send a campaign | §3 | segment, consent basis, copy, sender, timing |\n| Diagnose deliverability | §11 | domain, ESP, bounce + complaint rate, recent changes |\n| Write or de-slop copy | §4 | audience, offer, voice, one real proof |\n| Design an email | §5 + §16 | brand tokens, archetype, goal |\n| Pick a platform | §15 | list size, use case, stack, budget, agent-driven? |\n| Pull a benchmark | Appendix | industry, email type |\n| Cold outbound | §14 | offer, ICP, domains, volume |\n| WhatsApp / SMS / RCS | §Messaging | channel, consent basis, region |\n\n## 2. AI EMAIL AUTOMATION (the operating model)\n\nThe marketer moved from operator to director: brief the agent, govern it, own the send button. Most major ESPs now ship a human-gated prompt-to-campaign agent, an MCP server or a Claude/ChatGPT app (§15); advise on the surface the user runs.\n\n**The loop: read state → reason → act → verify.** Read the account first (lists, flows, recent campaigns, deliverability, suppressions), act on one thing, verify it. Opening prompt: \"audit my account and tell me what is missing\".\n\n**Automate:** send-time optimisation, subject-line variants + A/B, cart/browse triggers, post-purchase cross-sell, first-draft copy. **Keep human:** brand voice, strategy (segment priority, flow order), creative direction, domain and deliverability, the final send.\n\n**Autonomy dial.** Ask mode by default; widen only on narrow, reversible, low-brand-risk tasks, with an undo; read before write access. Supervised autonomy is the production stance. Where \"AI optimisation\" means bandits reallocating live traffic, measure with holdouts (never last-touch credit) and do-not-optimise constraints (margin, fatigue, complaints, brand safety).\n\n**Silent failure is the real risk** (a flow that quietly stops, caught days later): schedule a recurring health digest of flows not fired, flows erroring, metrics dropped.\n\n## 2b. FIELD NOTES: RUNNING AN ESP FROM AN AGENT (JUN-SEP 2026)\n\nThree months running Nitrosend's own sending through agents; each rule cost a real mistake. First five are Nitrosend mechanics (check your ESP's equivalent); the rest hold anywhere.\n\n- Optimistic-concurrency version (`if_version`) on every write; on conflict, re-read and retry with the fresh version, never guess.\n- Re-assert brand or account before every write batch after idle; MCP context resets silently to the default brand while reporting a deliberate selection.\n- Silent-parameter APIs default to send-to-all: pre-flight assert audience id and count, never probe a mutating endpoint on a live audience (one unknown body key mailed 1,003 contacts).\n- Liquid merge defaults go unquoted inside `href`; inner quotes close the attribute and break the link.\n- Animated WebP rather than GIF for heroes; then fetch the served URL and confirm it still animates (CDN variants can flatten to frame one).\n- Set text and button text colours explicitly on every design; theme defaults drift (grey headlines, dark text on a coloured button).\n- Decode tracking-wrapped CTA URLs before approving; the wrapper hides the target.\n- Never backfill or re-dispatch failed sends without a human order; late sends look worse than none.\n- Drafts by default; the literal \"send it\" in chat is the only thing that fires a blast.\n- Every email gets a hero, a live-text headline and one button; secondary content gets inline links.\n- Quote tiles come from HTML in headless Chrome, never an image model (garbled type, invented names).\n- Migration opt-out state comes from the old ESP's API, never a list CSV; exports drop unsubscribes.\n\n## 3. PRE-SEND CHECKLIST\n\nConfirm every line, surface it, wait for \"send it\".\n\n- [ ] Audience: size and segment logic verified against actual counts (AI segments run over-broad)\n- [ ] Suppressions: unsubscribed, bounced, complained, globally suppressed, frequency-capped, open support issue\n- [ ] Authentication: SPF, DKIM, DMARC aligned, p=quarantine or stronger (Outlook requires all three at 5K+/day)\n- [ ] One-click unsubscribe (RFC 8058) + physical address present\n- [ ] Copy: §4 pass, one CTA, subject ≤45 chars, preview text adds information\n- [ ] Design: single column ≤600px, dark-mode safe, alt text, live-text headline, explicit text and button colours, images <200KB each and <800KB total, cross-client preview, spam score, hero animates at the served URL\n- [ ] Links: wrapped CTAs decoded, no placeholder URLs, merge defaults render inside `href`\n- [ ] Sender: correct from-name + monitored reply-to; brand and account re-asserted; send time set; consent basis valid for this audience and content\n- [ ] Non-email: US SMS 10DLC brand + campaign registered; WhatsApp opt-in for the category + approved template; quiet hours per recipient local time (SMS 8am-9pm)\n- [ ] Kill switch: batched or throttled send with a working pause and rollback plan\n- [ ] Test send reviewed in a real inbox with real merge data\n- [ ] Personalisation confidence, inventory and pricing freshness checked; kill plan named\n- [ ] Human approval captured\n\n## 4. ANTI-SLOP COPY PROTOCOL\n\nRaw LLM copy is a deliverability liability, not only a quality one: Google filters high-AI-similarity text harder.\n\n- **The deepest tell is the absence of stakes.** Put **one genuine, defensible opinion in every email.** Ask the draft where it is too safe.\n- **Burstiness.** Alternate long and short sentences; a 3-5 word line after a long one, at least once per section.\n- **Blacklist (lint before send):** delve, leverage, foster, ignite, empower, unleash, streamline, navigate, seamless, robust, cutting-edge, transformative, multifaceted, pivotal, dynamic, comprehensive, tapestry, landscape, beacon, realm, journey, furthermore, moreover, \"in today's fast-paced\", \"I hope this email finds you well\".\n- **Syntax fingerprints (survive find-and-replace):** \"it's not X, it's Y\", rule-of-three padding, copula avoidance (\"serves as\" for \"is\"), em dashes.\n- **Specificity is the cheapest humaniser.** Real numbers, names and dates. Pull one real metric from the brand's own data into every email.\n- **Workflow:** human strategy → AI draft → human edit. High-personality formats (founder letter, welcome): rough human notes first, AI tightens. Never AI-first.\n\n## 5. AI EMAIL DESIGN PROTOCOL\n\nAI defaults to competent and generic; force it off its defaults.\n\n- **Two readers: the human and the summariser.** Gmail's Gemini and Apple Intelligence summarise from the opening live text (rollout tiered). Front-load the offer in real text, semantic headings, never image-only; live text also wins accessibility and dark mode.\n- **Context beats prompt.** Feed brand kit, design tokens, a tested module library and a rules file before iterating on wording.\n- **Safe substrate.** Emit MJML, React Email or Maizzle (compile to inbox-safe HTML), never raw HTML from a prompt.\n- **Anti-slop design rules:** own one colour (30-60% of the surface); restraint over decoration; real photography, never AI stock; bold live-text headlines; one message, real negative space. Ban the purple-to-blue gradient and the beige wash.\n- **Compliant by default:** single column ≤600px, 44px tap targets, `role=\"presentation\"` tables, dark-mode-safe colours (~#121212, never pure #000 backgrounds or #fff logos), alt text everywhere, explicit text and button colours.\n\n**Direct the agent: Discover, Define, Deliver.** Adapted for email from Anshu Chimala, \"How to turn your AI into a world-class designer\" (Lenny's Newsletter, 1 Sep 2026, https://www.lennysnewsletter.com/p/how-to-turn-your-ai-into-a-world) via the design-director skill (command, counts and brief format are the skill's). LLMs predict the median; divergence has to come from outside the model.\n\n- **Seed strings.** The agent generates a random string in a shell (`openssl rand -base64 48`), derives palette, layout and type from its patterns, never reveals it; new string per direction.\n- **Broad before deep.** Ask for 12-20 directions as one-liners, \"go broad, not deep\". The human picks from text before any image or code exists. Reject anything guessable from the category alone.\n- **Ambitious briefs.** One sentence naming a real reference (Graza's chartreuse drench, Aesop's restraint) plus two anti-references.\n- **The critic loop.** Screenshot the rendered test send and hand it to a separate, stronger model in a fresh context (no code, history or earlier critiques). It names the aesthetic, imagines how a top studio would execute it, lists the biggest gaps and scores /10. Fix, re-screenshot, re-critique with the same prompt (target score kept out of it) until the critic scores 9/10, capped at four rounds. The critic is ~10% of output tokens and most of the taste.\n- **Chain models.** Code model for structure, image model for stills, video model for a looping hero or state transition. As of Sep 2026 (verify): Claude Fable 5.1 as critic; Claude Opus 5 or Sonnet 5 (Claude Code) or GPT-6 Astra (Codex CLI) as implementer; gpt-image-2 for stills; Gemini Omni 1.1 for video.\n- **Deliver by subtraction.** Cut glows, gradients, decorative containers and labels that repeat the visual, then a light anti-slop pass on copy (§4) and visuals (reflex fonts, centred hero + three cards, purple on dark).\n- **Keep failed prompts**; retest on the next model generation.\n- **Who to follow** (Chapter 18, 49 practitioners, five added in v2.7): Anshu Chimala @anshuc, Karri Saarinen @karrisaarinen, Ryo Lu @ryolu_, Jenny Wen @jenny_wen, Lee Munroe @leemunroe.\n\n---\n\n# PART B: REFERENCE\n\n## 6.
