Kit (formerly ConvertKit) vs MailerLite: at a glance
What is Kit (formerly ConvertKit)?
Kit handed page-building to an agent, then went back to cleaning up the subscribers list
The Kit MCP crossing from reading a creator's list to building and editing landing pages remains the defining recent release. Since then the work has been ordinary interface repair on the subscriber surface: the Subscribers page was reorganised around search and filtering, and bulk actions became a floating menu that follows the scroll instead of sitting at the top of the list. Creator Network connection requests and custom favicons round out the window.
What is MailerLite?
MailerLite ships two-way Shopify sync and an AI agent skill while building out its editor with code blocks and video.
MailerLite is shipping steadily on two tracks: deepening its e-commerce integrations (two-way Shopify sync, product variant targeting for purchase triggers) and expanding the editor's capability surface (code blocks, video blocks, full color picker, copy-paste across all automation steps). The ChatGPT directory listing and the email marketing skill for AI agents signal an early positioning in the AI tooling ecosystem.

◆ Current state
The Kit MCP crossing from reading a creator's list to building and editing landing pages remains the defining recent release. Since then the work has been ordinary interface repair on the subscriber surface: the Subscribers page was reorganised around search and filtering, and bulk actions became a floating menu that follows the scroll instead of sitting at the top of the list. Creator Network connection requests and custom favicons round out the window.
◆ Where it's heading
The Kit MCP is the axis, and it has already made its jump — from read-and-analyze in May to producing the published artifact in July. What follows is consolidation: the manual surfaces are being tidied so the things an agent can do and the things a creator does by hand sit on comparable footing. Nothing in this window extends the MCP itself, which makes the current period a pause rather than a redirection.
◆ Prediction
Expect the MCP surface to extend to more of the artifacts Kit publishes now that landing pages have proven the pattern. The subscriber-page work reads as a finished cleanup rather than the start of a larger rebuild.
MailerLite
6.3MKT AUTO
MailerLite ships two-way Shopify sync and an AI agent skill while building out its editor with code blocks and video.
◆ Current state
MailerLite is shipping steadily on two tracks: deepening its e-commerce integrations (two-way Shopify sync, product variant targeting for purchase triggers) and expanding the editor's capability surface (code blocks, video blocks, full color picker, copy-paste across all automation steps). The ChatGPT directory listing and the email marketing skill for AI agents signal an early positioning in the AI tooling ecosystem.
◆ Where it's heading
The two-way Shopify sync is the clearest signal of where this is heading: MailerLite wants to be the authoritative subscriber record, not just a send layer on top of Shopify data. The AI agent skill points toward MailerLite becoming accessible to AI coding agents — a channel that could drive meaningful developer adoption if other integrations follow the same pattern.
◆ Prediction
Variant-level purchase triggers will roll out to Shopify, WooCommerce, and BigCommerce, and the two-way sync will likely expand to other e-commerce platforms. The AI agent skill will probably be expanded to cover more campaign operations as AI coding tools become more widely used.
