Support in-app messages for multiple mobile apps in the same workspace
Customer.io adds in-app message targeting for the Messaging Mobile SDK, letting teams choose specific apps and platforms within one workspace and avoid workarounds when managing overlapping mobile audiences.
Messaging
Mobile SDK
If you have multiple mobile apps with overlapping audiences, you can support both apps in the same workspace. When you send an in-app message, you can choose the apps and platforms you want to show your in-app message on—no more page-rule workarounds or separate workspaces to keep messages out of the wrong app.
If you have multiple apps in your workspace, in-app messages will show a Where this message appears setting. From here, you’ll choose the app your message belongs to and the platforms where you want to show it.
You’ll need to update your mobile SDK to support this feature. If you have multiple apps that you manage across workspaces today, and you want to consolidate them to a single workspace, you need to wait until a significant number of devices have updated to the new SDK version before you consolidate workspaces.

Use Customer.io AI in Slack
Customer.io brings its AI agent to Slack so users can ask questions and hand off messaging work from threads or DMs.
AI
The Customer.io AI agent now works in Slack. You can @Customer.io in a thread to ask it questions about your data and workspace. Or you can message it directly and give it work—without opening Customer.io.
With the Customer.io Slack app, Customer.io becomes another collaborator in your work. You can have a conversation about the messages you want to send and hand the work off to @Customer.io all in one place.
We’re rolling the Customer.io Slack app out to accounts through August 22. If you don’t see Slack Agent options in your settings yet, it’s on the way.

Control how fast your automations send messages
Customer.io adds per-channel rate limits and a wait-before-continuing step for automations and API-triggered broadcasts.

To account for rate limits, you can now enable Wait before continuing journey for any message to make sure people receive your messages before moving forward in your automation.

Geofences: message people when they enter or exit a location
Customer.io adds geofencing for Messaging Mobile SDK, letting teams trigger workflows when people enter or exit physical locations and send timely location-aware messages across channels.
MESSAGING
MOBILE SDK
You can now trigger workflows when a person enters or exits a physical location, like a store, a parking lot, a venue, and engage them across any of your message channels. Geofencing helps you send timely, location-aware messages without building custom location logic or relying on a third-party geofencing integration.
Geofences are available on Premium and Enterprise plans. You can trigger automations, group people into segments, and add geofence conditions to wait actions in automations. You can track when people enter or exit a geofence in their activity logs.

Add reusable knowledge sources to LLM actions
Customer.io improves AI messaging UI with reusable knowledge sources for LLM actions and the Agent.
AI
MESSAGING
UI IMPROVEMENTS
You can now attach a file, a Google Drive doc, or query recent events as a knowledge source and reuse it across LLM actions, instead of pasting the same text into every prompt. Reference the knowledge source name in the prompt to tell the LLM how to use it.
Save any source to the workspace-scoped Knowledge Library and attach it to one or more actions.
Knowledge sources are also available to the Agent if you want to use them as context for other requests.

Store a copy of a push in your notification inbox
Customer.io adds notification inbox copies for push messages so recipients can revisit missed pushes or see them on unsupported devices.
MESSAGING
When you send a push notification, you can now add a copy of it to your notification inbox. This way, people can revisit the message after dismissing the push or still receive your message if they don’t have a device that can receive it.
Push notifications are easy to miss: people dismiss them by accident, or don’t have a device that can receive them. Now you can give any push a home in your notification inbox.

Date triggers now include custom objects
Customer.io adds automation triggers from custom object date attributes for reminders and renewals.
MESSAGING
You can now trigger an automation off a date attribute on a custom object. This means you can send messages relative to a date stored on an object, like trigger reminder campaigns based on reservations or membership renewals, and avoid storing duplicate data on people’s profiles!

Preserve unsubscribe preferences when merging profiles
Customer.io adds workspace merge settings that preserve unsubscribe preferences during profile merges.
MESSAGING
When you merge profiles, the primary profile’s settings take precedence over the secondary profile’s settings. However, now you can update your workspace merge settings to preserve unsubscribe preferences no matter which profile is primary. This helps prevent you from messaging people who opted out.

Set up channel-based message limits
Customer.io adds channel-based message limits across email, SMS, push, and webhooks with longer time-frame controls.
MESSAGING
You can now set up channel-based message limits for email, SMS, push notifications, and webhooks. Historically, you could only set a single message limit across your message channels.
You can add per-channel or shared message limits to ensure your audience receives the right number of messages in a specific time frame. With this release, you can also set a wider time frame for your message limit. Instead of 7 days, your message limit can be up to 31 days.
You can limit the number of WhatsApp and SMS messages sent via Twilio, but not other vendors.
