SubPollen matches niche newsletter writers with complementary audiences — trading, crypto, fitness, and more. We auto-generate personalized cross-promo emails and track every subscriber swap for you.
Tell us your niche, subscriber count, and what makes your audience tick. Takes 2 minutes.
Our algorithm finds complementary newsletters — not competitors. A fitness writer paired with a mental health newsletter, for example.
We auto-generate a personalized cross-promo email for both writers. Send it, and watch subscribers roll in — tracked in real time.
