ConvertKit vs MailerLite
A side-by-side editorial comparison of ConvertKit and MailerLite — release velocity, themes, recent moves, and the top alternatives to consider.
ConvertKit vs MailerLite: at a glance
What is ConvertKit?
Kit ships an MCP server so AI tools can run email campaigns, while the rest of the surface gets quiet polish.
The headline release is Kit MCP in beta — an MCP server that lets Claude, ChatGPT, Cursor, or any MCP-compatible client manage Kit lists, tags, broadcasts, and sequences from natural-language prompts. Around it, the team shipped routine UX work: searchable Rules and Visual Automations libraries, a typo-catcher on signup forms, a unified Recommendations view, and Shopify sync added to the Free plan.
What is MailerLite?
MailerLite is quietly becoming a creator commerce stack — email is just the front door now.
MailerLite has expanded well beyond its email-marketing core. Recent releases add free and paid digital products, 1:1 and group bookings with calendar sync, and Stripe-driven promotional automations launched straight from product pages. The May editor rebuild adds an in-flow AI agent for HTML email composition, putting embedded LLM editing on a surface most competitors still treat as static.

Kit ships an MCP server so AI tools can run email campaigns, while the rest of the surface gets quiet polish.
◆ Current state
The headline release is Kit MCP in beta — an MCP server that lets Claude, ChatGPT, Cursor, or any MCP-compatible client manage Kit lists, tags, broadcasts, and sequences from natural-language prompts. Around it, the team shipped routine UX work: searchable Rules and Visual Automations libraries, a typo-catcher on signup forms, a unified Recommendations view, and Shopify sync added to the Free plan.
◆ Where it's heading
Kit is making a serious bet that creators will manage their email programs through external AI assistants rather than (or alongside) the Kit dashboard. The MCP server is a meaningful surface move; everything else in this batch reads as housekeeping intended to make individual primitives more discoverable for both humans and agents.
◆ Prediction
Expect MCP coverage to widen from analysis/tagging to outbound campaign creation by GA, and the Shopify-on-Free move to be repeated for Stripe or Gumroad to widen the creator-commerce funnel.
MailerLite
6.3MKT AUTO
MailerLite is quietly becoming a creator commerce stack — email is just the front door now.
◆ Current state
MailerLite has expanded well beyond its email-marketing core. Recent releases add free and paid digital products, 1:1 and group bookings with calendar sync, and Stripe-driven promotional automations launched straight from product pages. The May editor rebuild adds an in-flow AI agent for HTML email composition, putting embedded LLM editing on a surface most competitors still treat as static.
◆ Where it's heading
The arc is from 'send newsletter' to 'run a creator business from one tab.' Each shipped feature tightens the loop between audience, offer, and automation — bookings trigger email sequences, product pages spawn campaigns, and the new Custom reports let operators attribute growth across email, products, and calls. Internal UX work (brand styles moved to its own section) reads as housekeeping ahead of another expansion wave rather than as user-facing change.
◆ Prediction
Expect the AI agent to step out of the HTML editor and into the automation builder and product-page copy next, and for the Stripe-product-to-automation pattern to grow into reusable multi-step funnels. The Bookings module is the next obvious place to add analytics into Custom reports.
