What problem does it solve? Cold outbound campaigns fail when emails are generic, poorly sequenced, or land in spam. This Skill turns Claude into a cold email strategist that drafts persona-specific emails, structures multi-touch sequences, and diagnoses deliverability problems using frameworks distilled from 10M+ sent emails. ## Core Features & Use Cases - Persona-Based Routing: Directs requests to sub-skills for ATL (VP/C-Level) or BTL (Manager/IC) messaging, first-touch emails, follow-ups, re-engagement, subject lines, and personalization at scale. - Copywriting Frameworks & Sequences: Provides 13 named frameworks (Do the Math, Pattern Interrupt, Upfront Value, etc.), a 4-email sequence structure (Day 0/3/6/10), and an e-commerce vertical playbook. - Deliverability & Infrastructure Guidance: Covers SPF/DKIM/DMARC setup, domain warmup, bounce management, spam word checking, and sequencing tool comparisons (Instantly, Smartlead, Lemlist, Emailbison). - Use Case: Ask Claude to write a cold email targeting VPs of Sales at Series B SaaS companies, and it routes to the ATL sub-skill, drafts a 2-3 sentence strategic email with a soft CTA, and runs a spam-word check before returning it. ## Quick Start Ask Claude to write a cold email for your target persona and offer, for example: "Write a first-touch cold email to a Head of Marketing at a mid-market SaaS company about reducing manual reporting work."
