Campaign Builder

Drop your URL and a CSV of prospects. Get a research brief + 2 personalized cold emails for each. BYOL — bring your own list. Free CLI from BuzzLead.

The same engine that powers the free web tool — but you can throw an unlimited prospect list at it from your terminal.

npx @buzzlead/campaign-builder \
  --my-site mycompany.com \
  --input prospects.csv \
  --out campaign.csv

For each row in your CSV, you get back:

• A short research brief (what they do, growth signal, main challenge, best angle)
• Email 1 — 4T framework, under 70 words
• Email 2 — tight problem-frame follow-up, under 90 words

No DiscoLike, no AI Ark, no contact lookup. You already have the list. This is the tool that turns your list into copy.

What it does

For each prospect in your input list:

1. Crawl their website via Jina Reader
2. Build a research brief — Claude extracts what they do, their growth signals, their likely main challenge, and the best cold-outreach angle
3. Write Email 1 — 4T framework (Trigger / Think / Bridge / Talk), peer-to-peer voice, under 70 words
4. Write Email 2 — problem-frame + mechanism + soft CTA, under 90 words, different angle from Email 1

Combined with a one-time analysis of your own site (the sender context), every email is personalized to the prospect's actual business.

API keys

Just one required.

Key	Why	Where
ANTHROPIC_API_KEY	Site analysis + research + email generation	https://console.anthropic.com

Optional:

• JINA_API_KEY — faster site scraping (anonymous works)

---

Cost per run

Approximate, at 10 prospects:

Provider	Calls	~Cost
Anthropic	1 (your site) + 3 × 10 (per prospect) = 31 calls	$0.20–0.50
Jina	11 scrapes	~$0.01
Total		~$0.20–0.50

Scales linearly. For 100 prospects: ~$2–5.
