Step-by-Step Guide

Build targeted prospect lists with Perplexity

Research your ideal prospects: decision-makers in target companies, their contact info, recent company news, and personal interests. Perplexity sources from LinkedIn, Crunchbase, and company websites with citations.

Pro tip: Prompt: "Find me 20 decision-makers in [industry] companies with [characteristic]. Include: name, title, company, LinkedIn URL, recent company news, and personal interests for personalization."

Write hyper-personalized email templates

Feed Claude each prospect's research data and ask for a personalized email. Include: reference to their recent work, a specific observation about their company, your value prop tailored to their context, and a low-friction CTA.

Pro tip: Prospect template: "Write a cold email for [name], CEO of [company]. They recently [achievement]. My product helps [value prop]. Keep under 100 words, show you researched them, end with a specific CTA."

Set up multi-step sequences

Create email sequences: Day 1 — intro email, Day 3 — value add (case study/article), Day 7 — social proof (testimonial), Day 14 — break-up email. Use tools like Lemlist or Instantly for automated sending with inbox rotation.

Pro tip: The best cold email sequences use 4-5 touches over 14 days. After that, move leads to a monthly nurture campaign. Respect inboxes and not every non-reply means disinterest.

Optimize deliverability with AI

Ask ChatGPT to review your emails for spam triggers: excessive exclamation marks, all-caps words, too many links, spammy words (free, guarantee, act now). Also set up proper SPF, DKIM, and DMARC for your sending domain.

Pro tip: Prompt: "Review this cold email for spam triggers. Flag: spam words, excessive punctuation, link density, subject line issues, and formatting problems. Score it out of 100 for deliverability."

Analyze and iterate with ChatGPT

Feed your campaign metrics (open rate, reply rate, bounce rate, meeting booked rate) into ChatGPT. Ask: "Analyze these 4 email variants. Which subject lines and body structures performed best? Generate 3 new variants that combine winning elements."

Pro tip: Track per-variant performance: 2 subject lines × 2 body styles × 2 CTAs = 8 variants. Test each on 50 prospects. After 400 sends, you know exactly what works for your audience.

Pro Tips

Set up a custom tracking domain to protect your sender reputation. Main domains used for cold email get blacklisted — use a subdomain like outreach.yourcompany.com

Warm up new sending domains for 2 weeks before launching campaigns. Send 5-10 emails/day initially, increasing to 50+ over 14 days

Use Claude to write the first email and ChatGPT to write follow-ups. Each model has a slightly different tone — variation across a sequence feels more natural

Aim for 0.5-2% reply rate on cold email. Higher than 3% suggests your list is too warm/small. Lower than 0.3% means your copy or targeting needs work

Common Mistakes to Avoid

Mistake: Using a single email template for all prospects

Fix: Personalize every email using prospect research. Even one personalized line referencing their work outperforms generic templates 3:1.

Mistake: Sending from unverified domains without proper email authentication

Fix: Set up SPF, DKIM, and DMARC before sending. Use tools like MXToolbox to verify your email setup. Undelivered email = zero ROI.
