Decision guide

1
Choose beehiiv if growth and publishing are the same thing in your business.

That is the cleanest fit when the newsletter itself is the product.

2
Choose ConvertKit if you want growth without narrowing the tool too early.

It stays the more flexible default if you want room to expand later.

3
Choose Substack if you want the simplest publishing path.

This is the fastest way to get moving, but it is not the best long-term control layer.
