NewsletterFit

NewsletterFit is a free decision tool for creators choosing between newsletter platforms like Beehiiv, Substack, Kit, Ghost, MailerLite and GetResponse. Enter your audience size, paid subscribers and monetization plans to compare estimated platform costs and understand how pricing changes as your newsletter grows. NewsletterFit also includes side-by-side platform comparisons, paid newsletter guides, break-even examples and fee calculators for questions like how much Substack takes. The goal is simple: help creators choose a newsletter platform based on real costs and their business model instead of generic “best platform” lists.
