Read receipts

Learn how read receipts work in iOS.

Starting with iOS version 2.4.8, chat messages sent from agents to customers will display a delivered or seen status. Previously, we only displayed Sent via chat.


Example of the Seen read receipt in the Kustomer timeline.

The following list shows available read receipts:

  • Sent via chat - Message was sent from Kustomer
  • Delivered - Message was delivered to the chat user, but chat user is not currently viewing the conversation and has not seen the message.
  • Seen - Indicates that the chat user has seen the message.



  • Read receipts are not backwards compatible and all conversations created on older versions of iOS are not supported. Agents can hover over the meta data to determine if read receipts are supported in their iOS version.
  • The iOS SDK does not use background app refresh. This means that the message will remain in the Sent via chat status if the user is chatting from an app that is running in the background or their phone screen is turned off/locked. Once the app is brought back to the foreground, the message will be Delivered.
