Kit
Newsletter and creator-commerce platform, formerly ConvertKit, with a free tier up to 10,000 subscribers and built-in tools for sponsorships and paid products.
Who it's for
Creators who want a large free subscriber list and built-in ways to make money from it, and who don't need automations from day one.
Standout details
- The free Newsletter plan covers up to 10,000 subscribers with unlimited sends, forms and landing pages, but it is capped at one automation and one sequence, with no A/B testing or third-party integrations
- Kit raised Creator plan pricing in 2025, from $29/mo to $39/mo at 1,000 subscribers (about 34%), for new signups immediately and existing customers on their first bill after October 15, 2025, with no grandfathering; Creator Pro rose from $59/mo to $79/mo
- Kit shipped an official MCP server in May 2026 that lets AI assistants such as Claude, ChatGPT, Gemini, Cursor and Windsurf read subscriber data, draft broadcasts and build sequences from chat, with every write action requiring your explicit approval
- The Sponsor Network, new in 2026, matches newsletters of 10,000+ subscribers that publish at least weekly with advertisers and handles outreach, so you approve offers instead of pitching brands yourself
- Kit Commerce sells digital products, paid newsletter subscriptions and a reader tip jar directly through Stripe, without a separate storefront tool
What it is
Kit, the platform Nathan Barry founded as ConvertKit in 2013 and rebranded to Kit in late 2024, is an email and newsletter tool aimed squarely at creators rather than marketing departments. One account handles the newsletter itself, landing pages and forms, plus a growing commerce layer: paid subscriptions, digital products, a tip jar and, as of 2026, a managed Sponsor Network that pairs qualifying newsletters with advertisers.
In May 2026, Kit also shipped an official MCP server, so an AI assistant can read your subscriber data and draft or send campaigns on request instead of you clicking through the dashboard by hand.
Who should use it
Writers and creators building an audience who want the free tier to last a long time before they pay for anything, and who plan to make money from the list itself through sponsorships or digital products rather than a heavy automation funnel. The free plan runs to 10,000 subscribers, which covers most people for years.
What stands out
The free plan’s ceiling is the number people quote and the number that flatters Kit: 10,000 subscribers, unlimited sends, unlimited forms and landing pages, for nothing. What it withholds is anything past one automation and one sequence, and it has no A/B testing and no third-party integrations. In practice, most creators stay free until they want more than a single welcome automation, and that is the point at which Kit expects you to pay.
That payment point got noticeably more expensive in 2025. Creator jumped from $29 to $39 a month at 1,000 subscribers, a 34% rise, and Creator Pro went from $59 to $79. New signups paid the higher price from September 8, existing customers were moved onto it with their first bill after October 15 with no grandfathering, and Kit had already retired its old $9 to $15 entry-level plan for small lists months earlier. Reviewers tracking the change reported some users moving to MailerLite, EmailOctopus and FluentCRM over the increase.
The newer monetization features are where Kit is trying to earn that price back. The Sponsor Network, available to newsletters over 10,000 subscribers that publish weekly, matches you with advertisers and manages the relationship so you approve deals instead of cold-emailing brands. Kit Commerce sells digital products and paid subscriptions through Stripe on the same account. And Kit MCP, launched in May 2026, connects Claude, ChatGPT, Gemini, Cursor and similar tools directly to your subscriber list and sequences, with write actions gated behind your approval.
The verdict
Kit’s free tier is the best reason to start here: 10,000 subscribers before you owe anything, and no limit on how much you email them. The commerce and sponsorship tools give you a real path to revenue without bolting on another platform, and the MCP server is a genuinely useful extra for anyone already running their business through an AI assistant.
The 2025 price increase is the part to budget for honestly. Creator costs 34% more than it did, the cheap entry-level plan that used to sit below it is gone, and the change reached existing customers, not just new ones. If your list is happy on the free plan’s single automation, stay there. If you need real automations and the new Creator price is a stretch, it is worth checking what pushed other users toward MailerLite, EmailOctopus and FluentCRM before you commit your workflow to Kit.
Honest verdict
Kit's free plan is the most generous on-ramp in newsletter tools, up to 10,000 subscribers before you pay anything, and the built-in Sponsor Network and Commerce tools mean you can monetize without adding a second product. The 2025 price rise is the thing to plan around: Creator jumped 34% to $39 a month at 1,000 subscribers with no grandfathering, and Kit retired its old $9 to $15 entry tier first, so there is no cheap stepping stone once the free plan's single automation stops being enough. If you're an established list already paying the old price, or you need automations without a real budget for them, it's worth pricing beehiiv or MailerLite against Kit before you commit.
