Kit

Kit (formerly ConvertKit) is designed around creators — writers, YouTubers, course sellers. Tag-based subscribers, simple visual automations, sign-up forms, and a built-in commerce and recommendation network (Creator Network, Sponsor Network) make it as much a growth and monetization tool as an email sender. The free plan covers up to 10,000 subscribers.

For creators who sell digital products and want simple, reliable automation plus growth tools, Kit is purpose-built in a way general senders aren't.

Every place Kit shows up across Choose My Stack — the research it’s part of and the articles that cover it.
