What is Customer.io?

Customer.io spent the summer pushing messaging off the screen and into location, time, and the lock screen

The summer release cycle put more than ten features into the product, and the coherent ones are about context rather than content: geofences trigger workflows when someone enters or leaves a physical location, live notifications render as iOS Live Activities and Android Live Updates, date triggers now read attributes on custom objects, and a notification inbox retains pushes. Around that sits infrastructure work — SMS via Sinch, Infobip and Vonage, multiple mobile apps per platform in one workspace, send-rate controls on automations — and an LLM actions surface where knowledge sources can be attached once and reused across prompts. The most recent entry is editor ergonomics in Design Studio.

What is Formidable Forms?

Formidable Forms ships field-level abandonment drop-off graphs and conversational form drafts across its add-on ecosystem

Formidable is shipping a focused round of improvements across its add-on ecosystem: Abandonment v1.2 adds a drop-off graph showing field-level abandonment rates in the Reports tab, paired with draft save/resume for conversational forms. Stripe Forms v3.2 migrates to Stripe's current confirmCardPayment API. Conversational Forms v1.3 adds draft save/resume and start-over buttons. WPML Forms v2.0 redesigns the translation interface for per-language editing.

Customer.io spent the summer pushing messaging off the screen and into location, time, and the lock screen

◆ Current state

The summer release cycle put more than ten features into the product, and the coherent ones are about context rather than content: geofences trigger workflows when someone enters or leaves a physical location, live notifications render as iOS Live Activities and Android Live Updates, date triggers now read attributes on custom objects, and a notification inbox retains pushes. Around that sits infrastructure work — SMS via Sinch, Infobip and Vonage, multiple mobile apps per platform in one workspace, send-rate controls on automations — and an LLM actions surface where knowledge sources can be attached once and reused across prompts. The most recent entry is editor ergonomics in Design Studio.

◆ Where it's heading

The platform is expanding the set of things that can start a message and the set of places one can land, which is a different axis from the segmentation-and-copy tooling most of this category competes on. Geofences and live notifications both take work that previously required a specialist vendor or custom device code and make it a workflow primitive. The LLM actions work is following the same instinct — reusable knowledge sources are the beginning of prompt infrastructure rather than a prompt box — but it is the least developed of the threads. Meanwhile send-rate control and multi-app support read as enterprise deployment blockers being cleared.

◆ Prediction

Expect the location and live notification surfaces to gain the operational controls that continuous device features require, and the LLM actions path to keep accreting reusable pieces. Design Studio is receiving steady editor polish, so a broader component authoring release is plausible.

F5.0

Formidable Forms ships field-level abandonment drop-off graphs and conversational form drafts across its add-on ecosystem

◆ Current state

Formidable is shipping a focused round of improvements across its add-on ecosystem: Abandonment v1.2 adds a drop-off graph showing field-level abandonment rates in the Reports tab, paired with draft save/resume for conversational forms. Stripe Forms v3.2 migrates to Stripe's current confirmCardPayment API. Conversational Forms v1.3 adds draft save/resume and start-over buttons. WPML Forms v2.0 redesigns the translation interface for per-language editing.

◆ Where it's heading

The consistent pattern is bringing conversational forms to feature parity with standard forms: draft save, start-over, abandonment tracking, and repeater support are all landing in the conversational forms path this cycle. The Formidable MCP server (Forms API v2.0.1, from the prior cycle) signals an upcoming AI-native direction — form data and submissions becoming accessible to AI agents via MCP is a distinct product surface that hasn't been fully exploited yet.

◆ Prediction

The next likely move is an AI-assisted form builder or response handler that leverages the MCP server foundation, given the established MCP compatibility layer and the trend toward AI-native WordPress tooling.
