Data-backed email marketing skill for AI agents. Use when building or running email automation, driving an ESP from an agent (MCP/connectors), diagnosing deliverability, writing or de-slopping email copy, directing AI email design, choosing a platform, or pulling benchmarks. Covers flows, segmentation, compliance, cold email, WhatsApp, SMS and RCS, and 19 industry playbooks.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Email Marketing Bible, Skill Reference
By George Hartley, co-founder of [Nitrosend](https://nitrosend.com).
> v2.7, 8 Sep 2026. Distilled from the EMB (19 chapters, 908 sources, https://nitrosend.com/email-marketing-bible), from running SmartrMail (~12K customers, 6B emails, sold 2022) and three months running Nitrosend through agents.
> 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.

# PART A: OPERATING MANUAL
## 0. AGENT OPERATING RULES
Every segment, draft, campaign, flow or staged send on a real ESP is live. **Hard gates, never skip:**
- **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.
- **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.

How to install
mdr add davepoon/buildwithclaude/email-marketing-bible@sha256:08451e36aa41dd70The line at the top of this page pins the label git:20261009.d43ac6e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
