Which do you use?
Who Should Choose What?
→ Choose ConvertKit if:
You're a serious creator who sells digital products, runs automated email sequences, wants to keep 100% of subscription revenue, and needs advanced segmentation. ConvertKit's free plan (up to 1,000 subscribers) makes it easy to start, and you avoid the compounding 10% Substack fee as your revenue grows.
→ Choose Substack if:
You're a writer who wants to start a newsletter with zero upfront cost and benefit from Substack's discovery network. The 10% fee is a fair trade when starting out — Substack's recommendation system actively brings you new readers, something ConvertKit doesn't offer.
→ Consider neither if:
You're a growing newsletter that wants Substack's publishing simplicity with ConvertKit-like analytics. Beehiiv ($0-99/month) combines both worlds and is increasingly the preferred platform for newsletter-first creators.

Frequently Asked Questions
Editor's Take
Here's the math most people miss: if you make $5,000/month from paid subscriptions, Substack takes $500. ConvertKit charges maybe $79/month for that subscriber count. The break-even is around $800/month in revenue — above that, ConvertKit saves you real money. Below that, Substack's zero upfront cost and discovery network are worth the 10%.
