Email Marketing Bible
Overview
The Email Marketing Bible turns an agent into an email marketing operator. It covers building automation flows, segmenting audiences, writing and de-slopping copy, directing email design, diagnosing deliverability, and operating an ESP through MCP or connectors behind hard pre-send gates. Part A is the operating manual for when the agent acts; Part B is the dense reference (metrics, flows, deliverability, compliance, platforms, benchmarks and 19 industry playbooks).
Adapted from the official skill at CosmoBlk/email-marketing-bible (v2.7, 8 Sep 2026, MIT) by George Hartley, co-founder of Nitrosend. It is distilled from a 19-chapter guide built on 908 sources (nitrosend.com/email-marketing-bible) and from running SmartrMail (about 12,000 customers, 6 billion emails). Figures are mid-2026; verify anything volatile (inbox rules, ESP features, pricing, model names) before acting.
When to Use This Skill
- Use when building or editing email automation flows: welcome, abandoned cart, browse abandonment, post-purchase, win-back, sunset.
- Use when an agent drives an ESP through MCP, a connector or an API (Klaviyo, Mailchimp, Resend, Nitrosend and similar) to create segments, flows or campaigns.
- Use when diagnosing deliverability: spam or Promotions placement, bounce or complaint spikes, SPF, DKIM and DMARC problems, warm-up and ESP migrations.
- Use when writing, reviewing or de-slopping email copy, subject lines and CTAs.
- Use when directing AI email design or critiquing a rendered email.
- Use when choosing an ESP, pulling benchmarks, checking compliance (CAN-SPAM, GDPR, CASL, Australian Spam Act), or planning cold email, WhatsApp, SMS or RCS.
