A side-by-side editorial comparison of Litmus and ConvertKit — release velocity, themes, recent moves, and the top alternatives to consider.
Litmus's tracked feed is its marketing blog, not product releases — little product signal to read.
The feed SparkPulse crawls for Litmus is its marketing blog, not a product changelog. Recent entries are email-marketing advice — deliverability, reminder emails, micro-animations, GenAI risks — with no visible change to the Litmus product itself. Any velocity here reflects blog-post cadence, not shipping.
Kit pushes past email tooling toward audience intelligence and AI-tool access.
Kit (formerly ConvertKit) is layering two new capabilities on top of its email and automation core: subscriber intelligence and AI-tool integration. Alongside those, it shipped a navigation redesign, a rebuilt landing page editor, and a rename of Creator profile to Newsletter site. The base product keeps getting incremental search and editor polish while the headline bets are data and AI.

There's no product trajectory to infer from this source: it surfaces editorial content on email-marketing trends (deliverability, AI in the inbox, engagement tactics), not releases. Reading where Litmus the product is heading would require a different source — release notes or an actual changelog.
Insufficient product signal to predict a next move; the feed will most likely keep publishing email-marketing blog posts on its usual cadence.

The direction is from send-and-automate toward understand-your-audience and operate-Kit-from-anywhere. Subscriber Signals adds an audience data layer that competes with standalone enrichment tools, while the Kit MCP exposes the platform to external AI assistants. Together they reposition Kit as creator infrastructure rather than just an email sender.
Expect Subscriber Signals to move from early access toward general availability and the MCP to graduate from beta with broader write actions across lists, sequences, and broadcasts.
