In the Notification Centre module, we can create messages for all customers or customers within selected categories.

Messages can be sent via email and mobile push notification. For some customers, we can enable SMS messages too.
To create a message, first choose how you want it to be sent. For example, both email and push notification.

For each type, enter the message content. In the email field you can paste in prepared HTML content or edit the field using the built-in editor.
For example, here we’ll let our customers know that we have bacon, sandwiches and fresh juice available for breakfast. We’ll use mobile push notifications to get the message out.
And off it goes!
