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

  1. Confirm the target audience (ICP) and the core value proposition with the user.
  2. 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).
  3. Select the personalization level: Hyper-Personal (unique research per prospect), Account-Based (company-specific), Segment-Based (industry/role), or Volume (template with merge tags).
  4. Identify the key pain points and the strongest social proof (case studies, stats, named customers) to support the campaign.
  5. 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.
  6. Generate A/B subject-line variations and assign send timing per email, following references/output-format.md.
  7. Add personalization guidance, performance benchmarks, and optimization recommendations from references/optimization.md.
  8. 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.
