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 Postscript?

Postscript is handing SMS marketing to an agent that decides each subscriber's next message

Postscript is an SMS and RCS platform for Shopify merchants, and this archive shows it working two fronts at once. On acquisition it has multiplied the places a subscriber can opt in — embedded forms droppable on any page, standalone landing pages built on the popup editor, and Onsite Opt-in at Shoptin checkout. On messaging it is building Shopper, a conversational AI layer that now answers, analyses and increasingly initiates. The feed carries no publication dates, so this is an archive rather than a timeline.

Kit handed page-building to an agent, then went back to cleaning up the subscribers list

◆ 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.

Postscript is handing SMS marketing to an agent that decides each subscriber's next message

◆ Current state

Postscript is an SMS and RCS platform for Shopify merchants, and this archive shows it working two fronts at once. On acquisition it has multiplied the places a subscriber can opt in — embedded forms droppable on any page, standalone landing pages built on the popup editor, and Onsite Opt-in at Shoptin checkout. On messaging it is building Shopper, a conversational AI layer that now answers, analyses and increasingly initiates. The feed carries no publication dates, so this is an archive rather than a timeline.

◆ Where it's heading

The centre of gravity is shifting from campaign tooling to per-subscriber decisioning. Shopper began as a responder, then gained a research surface over its own conversations, and now decides send timing and content for each individual. Alongside that, RCS is the delivery-side bet: webviews, dynamic product photos and tappable suggested replies all work to make the message thread the destination rather than a pointer to the storefront. Experimentation is being pushed into more of the journey rather than confined to campaign sends.

◆ Prediction

Expect the remaining hand-built primitives — static flows and manual segments — to be folded into Shopper's decisioning, and each new RCS capability to keep shipping with an automatic MMS or browser fallback so merchants can adopt it without maintaining a second path.
