Email Marketing Bible: Claude Code Skill The most comprehensive email marketing knowledge base, built for Claude Code. 68,000 words. 908 sources. 4,798 insights. 44 expert contributors. 19 industry playbooks. 57 curated email designs. Distilled into a single skill file that turns Claude into an email marketing expert. Built by George Hartley (founder of SmartrMail, email marketing SaaS, 28,000 customers). Why this exists Most email marketing advice is surface-level. "Personalise your subject lines." "Segment your list." "A/B test everything." You've heard it. It doesn't help when you're staring at a 2% open rate wondering what's actually broken. This skill gives Claude the same knowledge that comes from running an email platform serving 28,000 customers: the patterns that repeat across industries, the mistakes that destroy campaigns, and the specific strategies that consistently generate outsized returns. Every claim is backed by data. Every recommendation has been tested by practitioners. No theory. No filler. Specific things you can implement this week. Install That's it. One command. Claude now has access to the full knowledge base.

The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
