# Newsletter and creator email for Indie SaaS

> Newsletter platforms for creators and SaaS founders — Beehiiv, Substack, Kit (ConvertKit), and the publication-as-business decision.

## TL;DR

Newsletter tools for indie SaaS split on philosophy: Substack is a publication network that takes a revenue share for cross-discovery; Beehiiv is a creator-business platform with ad network and Boost mechanics; Kit (formerly ConvertKit) is an email-marketing platform broader than newsletters. The right pick depends on whether the newsletter IS the business (Beehiiv), is one channel of a creator business (Kit), or rides a network (Substack).

## Products analyzed in this category

### Beehiiv

### Substack

Substack's funnel runs on the network-effect positioning. The platform sells the discovery graph as much as the publication tools.
