The mechanic
Link your newsletter and we analyze your open rates, click-throughs, and engagement patterns over the last 90 days.
Our engine finds writers with complementary audiences and similar engagement quality — not just subscriber count.
Trade subscriber segments automatically. If your swap brings net-positive engaged readers, Fleaux pays you via Stripe.
Why Fleaux
Existing newsletter cross-promo is a mess of DMs, inconsistent audiences, and zero accountability. Fleaux uses engagement data to match writers fairly and pays out via Stripe when a swap performs.
“I spent months manually swapping shoutouts with other writers. Half the lists were disengaged and the growth never stuck. I wish Fleaux existed then.”
