Sales template

Cold email personalizer

Writes one specific, honest opening line per prospect from facts you provide, for a person to review.

Job

Draft a personalised first line and short email per prospect, grounded in real facts.

Trigger

A new row in your prospect sheet.

Hand off to a person when

All drafts are reviewed by a person before sending.

Inputs & knowledge
  • Prospect name, company, role
  • One or two real facts (a recent post, a product page)
  • Your offer in one sentence
Tools / actions
  • Draft email into the sheet or your outreach tool (not send)
Rules
  • Only mention facts provided. No invented compliments.
  • Under 90 words. No fake urgency.

How to build it

  1. Collect real facts per prospect first (or use the lead research agent).
  2. Generate drafts in a sheet column.
  3. A person edits and approves before anything is sent.
  4. Keep a list of phrases to ban (flattery, fake familiarity).

System prompt

Replace the parts in {BRACES}. Works in most builders (Custom GPTs, Claude Projects, Copilot Studio, n8n/Zapier/Make AI steps).

Write a short cold email to {NAME}, {ROLE} at {COMPANY}.

Facts you may reference: {FACTS}
Our offer: {OFFER}

Rules: under 90 words; first line refers to one of the facts specifically; no flattery like "I love what you're doing"; one clear question at the end; no claims about results we haven't provided.

Test before you switch it on

  • Give no facts: it should write a plain email without fake personalisation.
  • Check banned phrases don't appear.
