Newsletter ad arbitrage scanner

Find newsletter ad inventory priced below the affiliate revenue it generates.

The scanner reads 200+ B2B newsletter rate cards every 6 hours. When a slot is priced below the affiliate revenue it can produce, you get a Telegram alert with the matched affiliate program and the booking URL. Buy the slot, run the affiliate offer, capture the spread.

Built by an operator who books these spreads himself.

How it works

1. Scanner runs every 6 hours

Paved, beehiiv, Sponsy, Passionfroot, and 200 hand-curated rate cards. Respects robots.txt and rate limits. Tracks every newsletter's sponsor price + estimated open rate.

2. Matches against your offer database

For each new listing, we compute expected affiliate revenue for 50+ pre-loaded B2B SaaS programs (HubSpot, Notion, ClickUp, Close, etc.). Spread = expected revenue − slot price.

3. Telegram alert within 60 seconds

Any slot with spread > 1.5× and a persona-match > 0.4 hits your Telegram. Includes the booking URL and the affiliate program to pair. Book, run, capture the spread.
