Customer.io — Marketing product updates and releases, tracked on megachangelog.
The Design Studio canvas editor now supports slash commands for adding blocks, keyboard shortcuts for navigation and resizing, and click-and-drag editing from any part of a component. These improvements make editing components more intuitive and efficient.
Added ability to enable "Wait before continuing journey" for any message to respect rate limits and ensure messages are delivered before proceeding with automation workflows.
Customer.io released ten new features including geofences, live notifications, an in-app notification inbox, and expanded SMS provider support, broadening messaging and engagement capabilities.
Users can now save sources to a workspace-scoped Knowledge Library and attach them to one or more LLM actions. Knowledge sources are also available to the Agent for use as context in other requests.
Geofences are now available on Premium and Enterprise plans, allowing you to trigger automations, segment people by location, and add geofence conditions to wait actions. User activity logs track when people enter or exit geofences.
Customer.io now supports additional SMS providers beyond Twilio, allowing you to integrate with Sinch, Infobip, or Vonage per workspace for better regional coverage and subaccount management.
Workspaces can now send push notifications to multiple mobile apps simultaneously. Existing customers need to contact their CSM to enable this feature. When enabled, push delivery metrics will track one delivery per device instead of per customer profile.
Live notifications enable real-time updates within your app using Customer.io native iOS and Android SDKs. Developers define activity data models and render custom experiences while Customer.io handles push token management and delivery through APNs and FCM.
Push notifications can now be stored as copies in the notification inbox, ensuring users don't miss messages they accidentally dismiss or can't receive on a device.
Date triggers can now be created using custom objects, allowing you to set up automations based on important dates within your custom data. You can further refine your audience using filters and audience settings.
When merging customer profiles, you can now configure workspace settings to preserve unsubscribe preferences from either profile, preventing accidental messaging to opted-out customers regardless of which profile becomes primary.
You can now add per-channel or shared message limits to control how many messages your audience receives in a specific time frame, with support for time frames up to 31 days. Message limits are currently available for WhatsApp and SMS messages sent via Twilio.
Customer.io renamed several UI components for clarity: Campaigns are now Automations, People is now Profiles, Broadcasts has split into Newsletters and One-time sends, and Analysis is now Reports. APIs and data structures remain unchanged for backwards compatibility.

Custom roles now support granular permissions to control who can execute workflows, send messages, and retry deliveries. Existing custom roles retain their previous permissions unless explicitly updated.
Users can now define custom exit conditions for automations independently from conversion criteria, giving more flexibility in controlling when contacts leave automation flows. Existing automations that tied exit conditions to conversion criteria continue to work unchanged.

Customer.io introduced a new workspace performance dashboard that lets you monitor the health of your workspace and troubleshoot issues proactively. You can access it from the main menu under Workspace performance.
LLM actions now enable personalization of messages, data enrichment, and dynamic audience targeting within campaigns. Each LLM action execution consumes AI credits as detailed in the Billing documentation.
