Your emails go to brands with no budget

The engine keeps only those already buying ads, and writes the message.

An animated diagram, demo data: advertisers from the Meta Ad Library, the contact email found, the lead scored, sent from Gmail inboxes, approaches A/B tested.

The problem

Cold outreach is wasted on companies with no budget. Brands already spending on ads are the right targets, but finding and qualifying them by hand is slow.

What I built

A multi-tenant engine: headless scraping of the Meta Ad Library, site crawling for contact emails, lead scoring with Claude, and sending through connected Gmail inboxes with warm-up, daily caps and spread-out send times.

Technical details

SSRF guard: redirects followed manually, host rechecked at every hop
Two-level row-level security: workspace, then restrictive per agent
Hand-written Gmail client: MIME, threads, attachments
Cloudflare email de-obfuscation and MX checks

Stack

TypeScript strict
Deno edge functions
Supabase Postgres
Playwright
Claude API
Gmail API

The result

Each email approach is A/B tested and ranked, on a sending setup built for about 60 inboxes.
