Overview

Push notifications and in-app messages disappear after a glance. Message Center gives your content a second life, so users engage on their time, and you don’t lose conversions. With our SDK component, you can integrate the Message Center into your app and start sending messages to the center within a day.

The Message Center is a scrollable list of cards, each displaying a message image, title, description, and call to action. Users can access it from a bell icon, tab, or any entry point in your app, and browse messages at any time.

How it works

For your users to start using the Message Center, you should integrate our SDK component and start sending messages.

To send a message to the app’s Message Center, simply send an inbox message passing title, description, image url, and CTA title. The Message Center component on the device parses the message payload and renders a list card automatically — no extra code on your end.

To send a message, include any combination of these keys in message content:

• crdl_inbox_title – text
• crdl_inbox_image – url
• crdl_inbox_description – text
• crdl_inbox_deep_link – url
• crdl_cta_text – text

Common Use Cases

Message Center is great for:

• Limited-time offers and promotions
• Loyalty or subscription updates
• Personalised recommendations
• Sale announcements and vouchers
• Trial or renewal reminders

Best Practices to improve engagement

To get the most out of the Message Center, we recommend giving users clear hints on how to access it from the app icon badge to in-app indicators:

• App‑icon badges – map the unread count to the app icon badge on the home screen. A number of unread messages often nudges users back into the app; many teams report a noticeable lift in daily opens.
• In‑app indicators – mirror the unread count (or a subtle dot) on a bell icon, tab, or toolbar button so users spot new content as soon as they launch the app.

Note: The SDK checks for new messages and updates the unread count, so you can refresh badges and indicators when the count changes – no custom implementation.

What the in-app component does

• Native feel – built for iOS and Android, it follows each platform’s feel, navigation and animation conventions.
• Persists automatically – messages stay visible until their expiration date.
• Built in analytics – the SDK fires analytic events out of the box, no effort on your part.
• Brand‑ready – adjust fonts and colors to match your guidelines.
