Customer.io Release Notes

DESIGN STUDIO

MESSAGING

You can set colors, fonts, and more in Global Styles to ensure brand consistency across your messages. They now apply to your in-app messages, in addition to emails made in Design Studio.
We’re in the process of rolling this out to all accounts this week.
Moving forward, new in-app messages will automatically pull from your global styles, and you can choose to sync existing messages to align them with your current branding.
This release also introduces the concept of publishing to in-app messages. When you publish styles, you decide which emails and/or in-app messages to update. This pushes changes to your workflows (campaigns, broadcasts, etc) so that whether you send a test message or the campaign is actively sending to people, your messages will use the current styles.

MESSAGING

You can capture feedback from your audience directly through Customer.io—without using a third-party form provider. We support forms with plain-text inputs and plan to add support for other inputs in the future—like checkboxes and radio buttons.

We capture form submissions with your users’ input as a part of campaigns, broadcasts, or newsletters. You can also trigger downstream campaigns when someone submits your forms to thank them for their feedback, request a follow-up meeting, or offer a discount!

MESSAGING

UI IMPROVEMENTS

You can now optimize images when you upload them through Design Studio to reduce file size and maintain quality—without using third-party tools. This helps reduce friction that can hurt engagement in your campaigns.
Large assets cause emails to load slowly, impacting success of your campaigns. With optimization, you can ensure graphics appear quickly (even on poor mobile connections) to prevent drop-off from blank screens and protect click-through rates.

DESIGN STUDIO MESSAGING UI IMPROVEMENTS

You can now create and save custom components directly from the visual editor in Design Studio! This makes it easier for any team member to manage reusable content like headers and footers.

Build a block using components in the visual editor, and then click to save it as a new custom component file. It’s immediately accessible in the Insert menu of the visual editor for reuse across your emails.

You can also detach components from the source file if you want to make changes unique to that email.

DESIGN STUDIO

You can now move and style multiple components at once in Design Studio emails and our in-app message editor. This can help you more quickly make a change across your entire message.
While message creation requires fine-tuning, it shouldn’t interrupt your creative flow. Previously, refining Design Studio emails or in-apps—like the padding on four different buttons—required you to go through a cycle of repetitive, manual adjustments. Now you can do this in a single, fluid motion: click, drag, and change your styles.
To make edits across multiple components, click and drag your cursor on the canvas to select multiple components.

UI IMPROVEMENTS

You can now select, move, and style multiple components at once with drag-to-select in Design Studio. This saves you the trouble of manually clicking into individual components to apply identical padding, typography, or colors settings, so it’s easier to design emails!

While email design requires fine-tuning, it shouldn’t interrupt your creative flow. Before now, refining something simple—like the padding on four different buttons—required you to go through a cycle of repetitive, manual adjustments. Now you can do this in a single, fluid motion: drag, select, and style. Now what used to be tedious maintenance is now rapid iteration, so you can focus on designing emails and not on what individual component you need to click next.

You have two ways to multi-select and make bulk updates:

• Drag to select multiple components, then apply changes from the properties panel.
• Shift-select the component layers you want to change, then apply changes from the properties panel.

DATA INTEGRATIONS

MESSAGING

Configure webhooks once in Workspace Settings, and reuse them across campaigns and broadcasts—without exposing API credentials to your whole team.

Why it matters:

• Less repetitive work & fewer errors. Define your webhook URL, headers, and auth details once, and reference them in any campaign.
• Updates at scale. When an API endpoint or auth header changes, update the configuration in one place and all referencing campaigns pick up the change automatically.
• Tighter security. Team members can select pre-configured webhooks without ever seeing sensitive data like API keys, auth tokens, or headers.

Only Account and Workspace admins can configure reusable webhooks.

MESSAGING

You can now use Wait Until to hold a journey until a condition on the object—or a relationship to the object—that triggered a campaign is true. This makes it easy to align messages and other workflow actions to object states or times for things like orders, subscriptions, appointments, and more.

For example, you can:

• Send a message when an order’s status is equal to delivered
• Send reminders based on important dates and times like Appointment.starts_at
• Provision an account or user when they activate a subscription
