What is Customer.io?
Customer.io adds hosted and embedded sign-up forms, so contacts can enter without custom code
Customer.io now captures contacts itself: sign-up forms can run in-app, embed on any page via a script tag, or live on a Customer.io-hosted page, and submissions create or update people in the workspace. That lands days after the public/private API key split and a new Object trigger, on top of an October of snapshot segments, geofence dwell time and Design Studio API coverage.
What is MailBeez?
MailBeez moves its addon catalogue onto V5 with the MAIA assistant, then grinds out 4.9.99 patches.
MailBeez is an email-marketing plugin for Zen Cart and similar shops, finishing a V5 platform rewrite. In late September most addons (review reminders, winback, abandoned cart, dunning) shipped V5 support and the MAIA assistant. October brought a prospects manager, customer insight and sender profiles in 4.9.99.11, followed by a run of small UI, analytics and maintenance patches.

Customer.io
5.0MKT AUTO
Customer.io adds hosted and embedded sign-up forms, so contacts can enter without custom code
◆ Current state
Customer.io now captures contacts itself: sign-up forms can run in-app, embed on any page via a script tag, or live on a Customer.io-hosted page, and submissions create or update people in the workspace. That lands days after the public/private API key split and a new Object trigger, on top of an October of snapshot segments, geofence dwell time and Design Studio API coverage.
◆ Where it's heading
The recent run pushes Customer.io upstream of messaging: it is taking on the steps teams used to wire themselves, from credential setup to audience capture to email content via API. Consent records, polygon geofences and dwell time show the same pattern on the data side, with more state recorded and acted on inside the platform.
◆ Prediction
Expect form-level follow-ups such as form-submission triggers or form analytics, since the rollout runs through 6 November and the entry frames forms as a journey entry point.
MailBeez
5.0MKT AUTO
MailBeez moves its addon catalogue onto V5 with the MAIA assistant, then grinds out 4.9.99 patches.
◆ Current state
MailBeez is an email-marketing plugin for Zen Cart and similar shops, finishing a V5 platform rewrite. In late September most addons (review reminders, winback, abandoned cart, dunning) shipped V5 support and the MAIA assistant. October brought a prospects manager, customer insight and sender profiles in 4.9.99.11, followed by a run of small UI, analytics and maintenance patches.
◆ Where it's heading
The V5 rewrite is in its stabilization phase: features have mostly landed and point releases now fix compatibility and performance. The next milestone is a 5.0 core release, which the 4.9.99 numbering suggests is close.
◆ Prediction
A V5.0 core release is the likely next major step; the entries do not give a date.
