ColdMail AI
The tool that does automatically what Hazel Lalonde did by hand. Find prospects, audit their websites for real flaws, generate professional cold emails, and send them via Gmail, Outlook, Yahoo, or your own server — all in one place.
The story behind ColdMail AI
One morning, we received this email at clickkitfree.com:
It was a great cold email. Professional, direct, pointed out a real flaw (SEO ranking), offered a clear solution (page 1 ranking), and ended with a simple call-to-action. No fluff, no AI-sounding buzzwords, no aggressive pitch.
But Hazel had to do all of that manually: visit our site, check our SEO ranking, identify the flaw, write the email, find our contact info, and send it. That takes 5–10 minutes per prospect. If she wanted to reach 100 businesses a day, that's 8–16 hours of manual work.
So we built ColdMail AI — a tool that does all of Hazel's work automatically. You enter a keyword like "plumbers in Chicago" or paste up to 10 URLs, and the tool finds prospects, audits each website for 8 real flaws (SEO, speed, mobile, HTTPS, content, etc.), extracts contact emails/phones/socials, and generates a personalized Hazel-style email for each one. Then you can send it via Gmail, Outlook, Yahoo, copy to clipboard, or send from your own server — all from one screen.
What is ColdMail AI?
ColdMail AI is an automated cold outreach tool with two core engines: a Lead Finder that searches the web for prospects matching your keyword, and a Real Flaw Auditor that visits each prospect's website, runs 8 technical checks, and generates a professional cold email referencing the specific flaws found.
Unlike generic "AI email writers" that produce vague "I noticed your company" templates, ColdMail AI actually reads the prospect's website, measures its load time, checks if it has a meta description, verifies HTTPS, counts the words, looks for H1 tags and Open Graph images, scans for contact emails/phones/social links — and then writes an email that references those real, verifiable findings. The prospect can't ignore it because the flaws are real.
The tool also handles the entire sending workflow: 5 send options (Gmail compose, Outlook compose, Yahoo compose, copy to clipboard, or server send via PHP mail()), editable subject and body, follow-up sequence generator (Day 3 + Day 7 breakup), spam score checker, win probability estimate, and best-time-to-send recommendation. Plus a built-in mini-CRM dashboard with prospect stats, top flaws, industry breakdown, CSV export (20 columns), and JSON backup.
Built for freelancers, agencies, and sales teams who want Hazel's results without Hazel's manual effort. Free 2 audits per day, premium $9 for 100 credits (one-time, no subscription).

Follow-Up Sequence
Each email comes with a Day 3 follow-up and a Day 7 breakup email. Editable, ready to schedule in your sequencer.
Spam Score + Win Probability
AI rates each email 1–10 for spam risk and estimates win probability (1–100%). Plus best time to send (e.g., "Tuesday 10:00 AM").
Browser-Style Navigation
Back ← / Forward → arrows at the top of the output panel let you revisit previous search results, audits, and prospect views. Alt+Left / Alt+Right keyboard shortcuts supported.
Mini-CRM Dashboard

Works on phone, tablet, and desktop. Layout adjusts from single-column on mobile to two-column on desktop. Touch-friendly buttons.
Dark + Light Mode
Auto-detects your system preference. Toggle-free — just set your OS theme and ColdMail AI follows.
The 8 real flaw checks
Every website ColdMail AI audits gets scanned for these 8 issues. The generated email references whichever flaws are actually found — so the prospect sees a real, verifiable problem, not a generic pitch.
If no flaws are found (rare — usually means the site is well-built), the email references "an opportunity to improve search ranking for local keywords" so you still have a relevant opening.
How it works
- Complete Sender Setup (one-time, 30 seconds): Enter your name, email, pick your Title/Role from 35+ presets (or type your own via "Other"), and pick your Service from 37+ presets (or type your own). These sign every email you generate.
- Find prospects: Either (a) enter a keyword like "plumbers in Chicago" on the Find Leads tab — the tool searches Google/Bing/DuckDuckGo and returns up to 10 websites, or (b) paste up to 10 URLs directly on the Single URL tab.
- Audit runs automatically: For each URL, the tool fetches the page, measures load time, checks meta description / viewport / HTTPS / H1 / OG image, counts words, extracts emails/phones/socials, and identifies the top 2 flaws.
- Email generates: AI writes a Hazel-style email (under 120 words) referencing the specific flaws found, signed with your name + title. Comes with subject line, Day 3 follow-up, Day 7 breakup, spam score (1–10), win probability (%), and best time to send.
- Review + edit: Subject and body appear in editable fields. Recipient email is pre-filled from the website scrape (or enter manually). Tweak any word — send links update live.
- Send: Click Gmail / Outlook / Yahoo to open the compose window with everything pre-filled. Or click Copy for clipboard. Or click Server to send via PHP
mail()fromsupport@yourdomain.com. - Track: Every prospect is saved to the Dashboard with full audit data. Export to CSV (20 columns) or JSON backup anytime.
The entire flow — from keyword to sent email — takes about 30 seconds per prospect. Bulk mode handles 10 URLs in 1–2 minutes.
Sample generated email
This email was generated for a hypothetical plumbing website with real flaws detected (missing meta description + 4.2s load time). Notice how it references the specific findings — that's what makes ColdMail AI emails effective.

FAQ
Is ColdMail AI really free?
Yes. 2 audits or searches per day, every day, no signup required. Premium is $9 one-time for 100 credits — no subscription, no renewal. Or add your own API keys (BYOK) for unlimited free use.
How is this different from OutreachPro AI?
OutreachPro AI is a full CRM + multi-channel platform (WhatsApp/SMS/LinkedIn) with 27 languages, 50+ industries, and 12 email types — built for agencies doing high-volume multi-channel outreach. ColdMail AI is focused and simple: it finds prospects, audits their websites for real flaws, generates Hazel-style emails, and sends them via Gmail/Outlook/Yahoo. It's the tool for someone who wants Hazel's results without Hazel's manual effort — no CRM complexity, no multi-channel, just clean cold email outreach.
What makes the emails "Hazel-style"?
The AI is prompted to write like Hazel Lalonde's original email: professional, direct, value-focused, under 120 words, with one specific flaw mentioned, a clear solution, and a simple reply CTA. It's explicitly told to avoid AI buzzwords like "delve", "leverage", "robust", "cutting-edge", "synergy". The result reads like a human marketing consultant wrote it, not like ChatGPT.
How does the Lead Finder work?
Enter a keyword like "plumbers in Chicago". If you've added BYOK Search API keys (Google CSE, SerpAPI, or Bing), the tool uses those first — they return the highest-quality results. If no BYOK keys are set, it falls back to DuckDuckGo HTML scraping (free, no key needed, up to 10 results). Each search consumes 1 credit.
What are the 8 real flaw checks?
(1) Missing meta description, (2) Page load time over 3 seconds, (3) Missing mobile viewport tag, (4) No HTTPS, (5) Missing H1 tag, (6) Missing Open Graph image, (7) Thin content under 300 words, (8) No visible contact info. Each is checked by actually fetching and parsing the prospect's HTML — not guessed.
How does email finding work?
Three methods, tried in order: (1) Scrape the website HTML for mailto: links and plain-text email patterns, filtering out sentry/wixpress/example/cdn/schema addresses. (2) Guess common patterns like info@, contact@, hello@ at the prospect's domain. (3) Manual entry — you type the recipient email yourself. The first valid email found is pre-filled in the "To" field, but you can edit it.
Which send option should I use?
Gmail / Outlook / Yahoo are best — they open your email provider's compose window with the recipient, subject, and body pre-filled. You review and click Send manually. This gives the highest deliverability because the email comes from your real email account. Copy is for pasting into any other app. Server send uses PHP mail() from support@yourdomain.com — fast but may land in spam because server IPs aren't warmed up. Use server send only for testing.
Can I edit the generated email?
Yes. Both the subject and body appear in editable text fields. The Gmail/Outlook/Yahoo send links update live as you type, so your edits are reflected when you click send. Same for the recipient email field.
What's the difference between Sender Setup's dropdown and "Other"?
The Title/Role dropdown has 35+ presets (Marketing Consultant, SEO Specialist, Founder & CEO, Web Developer, etc.). The Service dropdown has 37+ presets (SEO services, Web Design, Copywriting, etc.). If your role or service isn't listed, pick "Other" — a text input appears below the dropdown where you can type your own. Your custom value is saved and used in every email signature.
Do I need to set up Sender details before using the tool?
Yes. On first visit, the tool auto-redirects you to the Sender Setup tab. Every search and audit is gated — if your name or service is empty, the tool blocks the action and points you to setup. This ensures every email is signed off professionally with your real details, never with "Your Name" placeholders.
What does the back/forward navigation do?
The output panel has browser-style ← back and → forward arrows at the top. Every view (search results, audit result, prospect view, tab default) is pushed onto a history stack. Click ← to revisit the previous view, → to go forward again. Also supports Alt+Left / Alt+Right keyboard shortcuts. The title next to the arrows shows what you're currently viewing.
How does bulk URL mode work?
On the Single URL tab, check the "Multiple URLs (up to 10)" box. A textarea appears — paste up to 10 URLs, one per line. Click Audit. Each URL is fetched, audited, and gets its own personalized email. Results show success/failure per URL. Credits are consumed only for successful audits (failed fetches don't burn credits).
What's in the CSV export?
20 columns: URL, Title, Contact Emails, Phones, LinkedIn, Facebook, Twitter/X, Instagram, Flaws, Solutions, Load Time, Word Count, Email Subject, Email Body, Follow-up 1, Follow-up 2, Spam Score, Win Probability, Best Time to Send, Date Audited. Proper RFC 4180 escaping (commas, quotes, newlines handled) + UTF-8 BOM for Excel compatibility.
Are my BYOK keys safe?
Yes. BYOK keys are stored in your browser's localStorage only — they never touch our server's database. They're sent only to the API provider (Google, Groq, OpenAI, etc.) directly from your browser via the PHP proxy. We hash license keys with SHA-256 before storing them, and we don't track which keys you use.
Do premium credits expire?
Premium credits don't expire — 100 credits = 100 audits, use them whenever. 30-day money-back guarantee if you're not satisfied. License is locked to one device (browser fingerprint) to prevent sharing.
Can I use the emails commercially?
Yes. Output you generate is yours to use commercially. No attribution required. You're responsible for complying with CAN-SPAM, GDPR, and local anti-spam laws — only email businesses that have a legitimate interest, always include an unsubscribe option in real campaigns, and don't impersonate Hazel Lalonde.
