Cold Email Generator by lemlist Review
Introduction
Cold email remains one of the highest-ROI channels for B2B growth — but writing truly effective sequences is hard. Generic templates get ignored. Over-personalization eats hours. And A/B testing without data is guesswork.
lemlist’s Cold Email Generator cuts through the noise: a 100% free AI tool trained on 200+ million real cold emails that outputs personalized, multi-step sequences in under 30 seconds — no signup, no credit card. In this hands-on review, we test its output quality, customization depth, and real-world readiness for founders and sales teams.
What Is the Cold Email Generator?
As stated on lemlist’s official page, this tool leverages “AI trained on 200M+ cold emails” to help users “craft emails that are 7x more likely to get replies.” It doesn’t just draft a single message — it generates full, multi-email sequences (up to 4 steps), complete with:
- Personalized hooks (using prospect/company data)
- Value-driven body copy
- Clear CTAs
- Natural tone (no robotic “I hope this email finds you well”)
Input is minimal: your product, prospect details, and goal. The AI handles the rest — including emotional framing, objection handling, and follow-up logic.
Key Features
- ✅ 100% Free — No Signup Required — Just enter email to receive results
- ✅ Multi-Step Sequences — Outputs up to 4 emails (intro + 3 follow-ups)
- ✅ Personalization Tokens — Auto-includes {{first_name}}, {{company}}, {{role}}
- ✅ Goal-Based Optimization — Choose: Book a meeting, Get a reply, Promote a product
- ✅ “Humanize” Button — Rewrites AI output to sound more conversational
Note: Results are delivered via email (not in-browser), and processing takes ~1–2 minutes.
How to Use It (Step-by-Step)
- Visit https://www.lemlist.com/free-tools/cold-email-generator
- Enter your email (to receive results)
- Fill in:
- Your product/service (e.g., AI-powered CRM for SaaS teams)
- Prospect’s role (e.g., Head of Growth)
- Company industry (e.g., Fintech)
- Goal (dropdown: Book a meeting, Get a reply, etc.)
- Click Generate
- Wait 60–90 seconds
- Check inbox for downloadable sequence (text + copy-paste format)
💡 Pro Tip: Use the “Humanize” feature after generation to reduce AI tone — it adds contractions, colloquial phrasing, and subtle imperfections for authenticity.
Use Cases / Who Should Use This Tool
- 🎯 Founders launching first outreach campaigns
- 📩 Sales reps scaling personalized sequences
- 🎨 Freelancers pitching services faster
- 🧪 Growth marketers A/B testing subject lines & CTAs
- 📚 Students learning persuasive copywriting
It’s ideal for high-volume, high-relevance outreach — not for one-off, ultra-niche emails requiring deep expertise.
Pros and Cons
✅ Pros | ❌ Cons |
✔️ Truly free — no limits or watermarks | ✖️ Requires email (no instant in-browser preview) |
✔️ Output is structured, actionable, and campaign-ready | ✖️ No built-in A/B testing or performance analytics |
✔️ “Humanize” feature reduces AI-detection risk | ✖️ Limited control over tone (e.g., can’t force humor or formality) |
✔️ Based on real-world email data — not generic LLM patterns | ✖️ No integration with ESPs (e.g., no direct HubSpot sync) |
Is It Free?
Yes — 100% free, forever. No credit card, no trial, no paywall. Unlimited generations.
Alternatives
- Copy.ai / Jasper — general-purpose AI writers; cold email is just one template
- Hyperwrite — strong personalization, but capped free tier
- Manual writing — highest quality, lowest scalability
lemlist’s tool wins for B2B specialization, sequence depth, and zero-friction access — especially for early-stage teams.
Final Verdict
⭐ 4.8 / 5 — One of the most practical, high-leverage free AI tools for growth teams. By training on real cold email data — not just marketing theory — it delivers sequences that sound human and drive action. The “Humanize” button alone makes it stand out in an AI-saturated market.
Highly recommended as a starting point for any outbound campaign — especially when paired with lemlist’s Free Email Finder for end-to-end lead-to-outreach workflows.
