Cold Outreach
When to Use
Activate when a founder needs to write cold emails or LinkedIn messages to prospects, potential customers, investors, or strategic contacts. Also use when the user says "nobody replies to my emails," "how do I reach out to X," "write me a cold email," or "help with outbound."
Context Required
From startup-context or the user:
Target prospect — Name, role, company, and why them specifically
Research signals — Recent news (funding, launches, hires), LinkedIn activity, company growth data, or role/industry context
Sender positioning — Who you are, what you offer, your unique credibility
Platform — Email, LinkedIn, or both
Batch size — Single prospect or multi-prospect campaign
Work with whatever the user provides. A strong research signal and clear value prop is enough to draft. Note what would strengthen the message but do not block on missing inputs.
Workflow
Gather context — Read startup-context if available. Ask for missing info on prospect, value prop, and proof points.
Research the prospect — Conduct web searches for recent signals. The core principle: 10 minutes of research transforms a cold message into a warm one. Rank signals by strength:
Assign personalization tier — Based on research signals found:
Tier 1 (custom): Named signals across multiple research sources — fully personalized message
Tier 2 (templated + personalized): Company info and role context — template with personalized elements
Tier 3 (volume template): No signals found — use volume approach with strong value prop
Select mode based on scope:
Quick: Single connection request + follow-up for one prospect
Standard: Four-touch sequence for a prospect (default)
Deep: Multi-prospect system with A/B variant messages
Draft the sequence — Write messages following the structure and rules below.
Self-critique pass — Before delivering, validate that personalization connects to the problem. If you remove the personalized opening and the message still makes sense, the personalization is not working. Rewrite.
Output Format
Deliver all of the following:
Connection request (LinkedIn, max 300 characters) or Subject line (email, 2-4 words, lowercase)
Primary message — the full outreach text (emails under 125 words, InMails under 500 characters)
Follow-up sequence — with timing and a new angle per touch
Personalization notes — what to customize per recipient if sending to multiple prospects
Tier label — which personalization tier this message uses and why
Writes personalized cold emails by researching prospects, crafting attention-grabbing openers, and scoring drafts against a quality rubric. Use when the user asks to write cold emails, outreach emails, sales prospecting messages, outbound email campaigns, or B2B email sequences.
