​
A modern UI - that’s completely customizable

Courier Inbox SDKs provide a clean, modern UI out of the box with the option to fully integrate into your existing web or mobile design. Match your branding and theme the built-in UI, or supply your own views and components for complete customization while taking advantage of the SDKs’ message management. For integrations that require it, the Inbox SDKs also expose low-level APIs you can build on.

​
Real-time delivery

Inbox messages are delivered across devices in real-time across web and mobile. Message states — whether a message is read, opened, archived, etc. — are automatically synced so your users are always up to date, wherever they’re logged in.

​
Cross-channel integration

Inbox can be configured to work alongside other messaging channels, including email, SMS, and push notifications. For example, when a notification is sent to both inbox and email channels opening the email will mark the corresponding Inbox notification read. Learn more about cross-channel syncing and how to toggle this feature on/off.
