What is Formidable Forms?
Formidable Forms 7.0.1 makes the builder preview reflect more Pro settings as they change.
Formidable Forms v7.0.1 extends the live builder preview to more Pro settings and warns admins when a hardened [frm-field-value] lookup is blocked. Same-day add-on patches fix REST-submitted signatures and inline calendars on multi-page forms. The week before, v7.0 hardened field-value shortcodes and several add-ons (Views, Coupons, Landing Pages) gained their own MCP tools.
What is Customer.io?
Customer.io puts experiments inside automations and makes Design Studio the default editor.
Customer.io is consolidating messaging work into its own canvas. On November 9 Design Studio became the default email editor, covering SMS, WhatsApp and inbox messages too, and Experiments arrived for testing whole multi-step paths inside an automation. The week before brought dynamic SMS senders by country, click heatmaps and per-language rules for auto-translate, after sign-up forms, the Object trigger and new API keys.
Formidable Forms vs Customer.io: editorial side-by-side
Formidable Forms
5.0MKT AUTO
Formidable Forms 7.0.1 makes the builder preview reflect more Pro settings as they change.
◆ Current state
Formidable Forms v7.0.1 extends the live builder preview to more Pro settings and warns admins when a hardened [frm-field-value] lookup is blocked. Same-day add-on patches fix REST-submitted signatures and inline calendars on multi-page forms. The week before, v7.0 hardened field-value shortcodes and several add-ons (Views, Coupons, Landing Pages) gained their own MCP tools.
◆ Where it's heading
Formidable is doing two things in parallel: exposing each add-on to AI clients through MCP, one at a time, and tightening data escaping in the core after 7.0. The 7.0.1 warning shows the hardening has user-facing side effects the team is now smoothing over.
◆ Prediction
Expect more add-ons to gain MCP management and further 7.0.x patches around blocked lookups.
Customer.io
5.0MKT AUTO
Customer.io puts experiments inside automations and makes Design Studio the default editor.
◆ Current state
Customer.io is consolidating messaging work into its own canvas. On November 9 Design Studio became the default email editor, covering SMS, WhatsApp and inbox messages too, and Experiments arrived for testing whole multi-step paths inside an automation. The week before brought dynamic SMS senders by country, click heatmaps and per-language rules for auto-translate, after sign-up forms, the Object trigger and new API keys.
◆ Where it's heading
Releases are moving testing, translation and content creation into the places teams already build journeys, so fewer steps need an outside tool. Daily-cadence shipping across messaging, data and AI translation suggests a broad push rather than one flagship bet.
◆ Prediction
Expect Design Studio to add the channels it says are coming and Experiments to gain reporting or winner automation inside the workflow view.
