Customer.io Release Notes

UI IMPROVEMENTS

Now you can set your color scheme in Customer.io: light mode (the default), your system’s scheme, or switch to dark mode.

Click Settings in the top-right corner of Customer.io to change your Theme to System, Light, or Dark.

AI

You can now create custom skills for the agent so it can do things that you and your team do regularly in Customer.io. You might add skills to help the agent enforce your brand voice, review campaign drafts, or report metrics in a specific format.

AI

You can now independently control whether MCP connections can edit live data and access sensitive profile attributes. By default, both settings are off, ensuring that your external AI tools using our MCP connections can’t inadvertently expose sensitive data to AI tools or touch things like live segments and campaigns unless you explicitly let them.

AI

DESIGN STUDIO

You can now generate global styles in Design Studio from a website link you provide. Previously, you could only generate from one of your sending domains.

To get started, go to Design Studio > Styles!

UI IMPROVEMENTS

You can now log into multiple Customer.io accounts and switch between them without logging out.

If you manage multiple Customer.io accounts—for different clients, subsidiaries, or test and production environments—you no longer need to log out and back in to move between them. Just go to the workspaces dropdown in the top-left corner, click your account, and click Add another account to login to another one.

MESSAGING

UI IMPROVEMENTS

You can now use Reset message content to quickly change the email editor you’re using and start from scratch. This means you no longer have to delete email blocks in campaigns or switch message types in newsletters to start over and change email editors!

API DEVELOPERS

MESSAGING

You can now programmatically create and send newsletters from our API! This can help streamline your workflow if you create content outside Customer.io.

You can create and send a newsletter in a single request, or use the Send a newsletter and Schedule a newsletter endpoints when a draft is ready. You can pass optional rate limits on both calls.

UI IMPROVEMENTS

Your workspace has a new look and feel! You’ll see a revamped Home dashboard and a more organized navigation menu.

From the Home dashboard, you can see message performance at a glance and take action on your workspace. Pick up where you last left off or select a suggested action to get started.

DATA INTEGRATIONS

Go to the Workspace Performance dashboard to check the status of your workspace and monitor incoming data and outgoing messages. Use this dashboard to locate and troubleshoot performance issues.

You can also use this dashboard to optimize your workspace before issues arise! Go to Manage > Workspace performance to get started.

MESSAGING

Goals let you define specific outcomes you’re optimizing for—a purchase, a subscription upgrade, etc.—and measure achievement across campaigns and broadcasts.

Unlike campaign-specific conversion goals, you can now track outcomes that span multiple workflows to help you more holistically strategize around your messaging and data.

ADMIN BILLING

AI

LLM actions let you prompt an AI model and store the output as attributes for use later in a campaign. They use AI credits, a new currency in your account.

You can use LLM actions to personalize messages, enrich data, and create conditions to help you reach the right audience.

Each time an LLM action runs, it uses AI credits. Learn more in Billing.
