How It Works
Link your newsletter in 60 seconds. We pull your niche, audience size, and engagement — no spreadsheets.
Our algorithm pairs you with writers in adjacent niches who share your audience profile but don't compete.
Coordinate a mutual recommendation post. Each swap typically drives 30–200 new subscribers to your list.
