Less time writing, more revenue kept, and an AI agent that runs it all
Kit shines at automations, sequences, and funnels. If what you actually need is a great newsletter going out every week, AstroSend does the research, curates the content, and writes the draft for you.
Kit added an MCP on its paid plans. AstroSend was built around it: full block-level editing, content curation, sending, products, and analytics from Claude Code, Cursor, Codex, or any MCP client, on every plan.
Kit charges 3.5% + $0.30 on every paid product and newsletter transaction. AstroSend takes 0% on sponsorships, digital products, courses, and paid newsletters. Only standard payment processing applies.
Kit's free plan is generous on subscriber count but light on features, and its commerce fees grow with your revenue. AstroSend has one feature set, priced by list size, with 0% commission.
Our team migrates your subscribers, branding, and past issues for you. No exports, no downtime, no hassle.
