Cold Email Personalization
When to Use
Writing cold outreach, sales prospecting, or outbound B2B emails
Personalizing email openers from prospect research signals
Building multi-touch follow-up sequences
Reviewing or scoring email drafts before sending
Workflow
Map the ICP — Complete ICP & Objection Mapping. Gate: persona, top 3 objections, and desired next step are defined.
Research signals — Follow the Research Playbook to find custom signals from the last 90 days. Gate: at least 2 verified signals per prospect.
Choose campaign path — Pick Custom Signal, Creative Idea, Whole Offer, or Fallback from Campaign Types.
Draft the email — Apply Email Structure rules: plain text, 60-120 words, one CTA. Use Variable Schema for merge fields.
QA and score — Run the QA Checklist, then score with the Scoring Rubric. Gate: score >= 80 and 3:1 recipient-to-sender ratio.
Build sequence — Add follow-ups per Follow-Up Strategy, rotating value props each touch.
Principles
Message-market fit over cleverness — Show you understand the prospect's situation immediately.
Research is the personalization — Custom signals prove homework; never fabricate facts.
One job per email — Single sharp question or CTA; earn a reply, not a meeting.
Two personalization paths — Path A: custom signal research. Path B: whole-offer strategy. See Creative Ideas for Path B tactics.
Example
Signal found: Prospect's company posted a VP Sales hire on LinkedIn 2 weeks ago.
Subject: {{first_name}}, growing the sales team?
Body: Hi {{first_name}}, saw {{company}} just brought on a new VP Sales — congrats. Specifically, it looks like you're scaling outbound to {{customer_type}}. We helped [similar company] ramp 3 new reps to quota 40% faster by templatizing their top performer's research workflow. Worth a 15-min look?
Why it works: Uses a verified, recent signal in the first line; ties it to a specific, relevant outcome; single clear CTA.
