Cold Email Sequence Generator Skill for Claude

Cold Email Sequence Generator

Craft personalized, value-driven cold email sequences with optimal timing, A/B-tested subject lines, and integrated social proof. The goal of cold email is to start a conversation, not to close the sale in the inbox.

Contents

• references/email-templates.md — Per-position email templates (Emails 1-7), bodies, variables, and social-proof frameworks.
• references/output-format.md — Delivery structure, flow-and-timing table, sending best practices.
• references/optimization.md — A/B testing, performance benchmarks, segmentation, pro tips, setup checklist.
• references/quick-start-templates.md — Vertical-specific subject-line skeletons (SaaS, agency, partnership).

Workflow

• Confirm the target audience (ICP) and the core value proposition with the user.
• Select the sequence type: Classic Cold Outreach (7 emails / 2 weeks), Fast-Track (5 emails / 1 week), Long-Play Nurture (12-14 emails / 4-6 weeks), Event/Trigger-Based (3-5 emails), or Re-Engagement (5 emails).
• Select the personalization level: Hyper-Personal (unique research per prospect), Account-Based (company-specific), Segment-Based (industry/role), or Volume (template with merge tags).
• Identify the key pain points and the strongest social proof (case studies, stats, named customers) to support the campaign.
• Build the sequence using the per-position templates in references/email-templates.md. Vary the angle across emails: Introduction, Value Proof, Different Angle, Social Proof, Resource Share, Direct Ask, Breakup.
• Generate A/B subject-line variations and assign send timing per email, following references/output-format.md.
• Add personalization guidance, performance benchmarks, and optimization recommendations from references/optimization.md.
• Assemble the final deliverable in the structure defined in references/output-format.md.

Core Rules

• Always personalize the first line with something specific about the prospect or their company.
• Keep emails short; the best cold emails run under 100 words.
• Use one ask per email; never bury multiple CTAs.
• Honor replies immediately when a prospect says no or asks to stop.
• Run an A/B test on some variable in every campaign.
• Invest in follow-up: roughly 80% of responses come from emails 3-7.

Sequence Angle Map

| Email | Angle | Length | CTA |

|-------|-------|--------|-----|

| 1 | Introduction (problem + quick win) | 50-100 words | Soft ask |

| 2 | Value proof (case study) | 75-125 words | Specific meeting time |

| 3 | Different angle (alt pain point) | 50-75 words | Yes/no question |

| 4 | Social proof (peer validation) | 60-90 words | Simple reply |

| 5 | Resource share (give first) | 40-60 words | Soft (let me know) |

| 6 | Direct ask (clear value prop) | 30-50 words | Direct meeting request |

| 7 | Breakup (last attempt + opt-out) | 25-40 words | "Should I close your file?" |
