Email newsletters are the most valuable content channel a creator can build. Unlike social media followers, you own your email list. No algorithm changes, no account restrictions — direct access to your audience.
Beehiiv, Substack, and Kit (formerly ConvertKit) are the three most popular platforms for creator newsletters. They look similar on the surface but are built for different priorities.

“I sell courses, products, or services alongside my newsletter” → Kit Kit’s automation and commerce features support the full creator business model.
“I’m not sure yet” → Start with Substack (simplest) or Beehiiv free tier (most room to grow). You can migrate later.
