Kit vs Substack (2026): Which Is Better for Your Newsletter?
60 days. Same newsletter. Two platforms. Here is what actually performed better and why.
I ran the same newsletter on Kit and Substack simultaneously for 60 days, sending identical content to comparable seed lists. The verdict is not a tie. Each platform won decisively in different categories, and the right choice depends entirely on what you are optimizing for: speed-to-revenue, ownership, or product-creator workflow.
