作者以自製的 $27 LeadGen Agent Kit，取代每月 $49–$299 的潛在客戶開發工具組合

I replaced a $49–$299/month lead-gen stack with a $27 kit I own outright

Disclosure: this is my product. I built it, I use it myself, and this post is the honest tour of what's inside — including the numbers that don't flatter it.

Cold outreach tools charge you $49–$299 a month to rent your own leads. I sell services to local businesses, and I got tired of paying a subscription to press "send" on my own words. So I packaged my own stack into the LeadGen Agent Kit: 5 Python scripts, 4 SOPs, and 20 prompts. $27 once, $0 a month after that — https://rellief.gumroad.com/l/leadgen-agent-kit

What's inside

5 Python scripts (stdlib only, runs on your computer):

1. scrape_maps.py — find businesses by niche × city from OpenStreetMap. Free, no API key.
2. enrich_emails.py — find emails from business websites and validate them. Free, no key.
3. dedupe_score.py — dedupe and ICP scoring, tiers A/B/C/D. No LLM needed.
4. write_opener.py — personalized first-line openers and full drafts, rule-based.
5. send_track.py — send via your own SMTP with SQLite tracking, unsubscribes honored.

4 SOPs: 10-minute setup, 30-minute list build, safe sending, and a 90-minute-per-week routine.

20 prompts that turn Claude or ChatGPT into the copywriter: industry openers, follow-ups, reply qualification, A/B testing.

Plus a full guide with troubleshooting, scaling, and a legal checklist.

Requirements are boring on purpose: Python 3.10+, an email account, 90 minutes a week.

The honest math

100 raw leads → about 20 worth emailing → 3–8% reply rate on a clean list.

No "10,000 leads in 5 minutes." The scripts are the boring part. Verification and list hygiene are the 80% that decides whether any copy ever gets read — I learned that running the stack myself on 34 dental clinics in Tucson, where 9 email addresses came out and 7 of them were pattern guesses, not verified addresses.

The kit grades every prospect A to D before anything gets sent. A goes first, D never goes at all. That one rule protects your domain more than any subject-line trick.

Who it's for

Freelancers and micro-agencies selling services to local businesses — AI automation, web design, SEO, ads. If you need clients and hate subscriptions, this is the machine.

From zero to 30 personalized emails a day in about 30 minutes of setup, then 90 minutes a week to run it.

What it is not

It is not a done-for-you lead list, and it is not a promise of replies. Cold email is a verification game first and a writing game second — the kit gives you the verification machine and the writing prompts, but you still have to run the weekly routine and read your bounces.

And I'm not going to dress this up as a victory lap: no sales to report yet. The kit exists because I run this stack myself daily, and I'd rather own the tool than rent it.

Get the kit

The LeadGen Agent Kit is $27, one-time, no subscriptions: https://rellief.gumroad.com/l/leadgen-agent-kit

If you run cold outreach on free tools already, the scripts will feel familiar — the value is having the whole chain (scrape → enrich → dedupe → write → send) in one place, with the SOPs that tell you exactly when to run each step. Run one batch of 30 businesses this week and grade the list before you send a single email.
