WPForms makes its form builder operable by outside AI assistants like ChatGPT and Claude
A side-by-side editorial comparison of Sender and ConvertKit — release velocity, themes, recent moves, and the top alternatives to consider.
Sender is filling out from a budget email tool into a fuller marketing platform, now reaching into transactional sends.
Sender ships roughly monthly and has spent the past two quarters closing the feature gaps that separate it from pricier marketing platforms. December brought transactional emails — its first move beyond pure marketing sends — alongside a rebuilt dashboard; since then it has refreshed the email builder, added brand settings, and pushed ecommerce reports down to the Standard plan. Several feed entries are tutorials and best-practice posts rather than releases.
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.

The direction is breadth at an accessible price: landing pages, transactional email, ecommerce events and reports, all aimed at small ecommerce senders who'd otherwise stitch together multiple tools. Moving features down to lower plans points to a land-and-expand pricing strategy. Expect more ecommerce-trigger automation and continued parity-building with the Mailchimp/Brevo tier.
The next likely moves are deeper ecommerce automation — event-driven flows building on Custom Events — and further transactional and deliverability features now that that surface exists.

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.
