Communication Groups allow you to define reusable message templates for your automated communications. Each group contains the content and configuration needed to send messages through your configured channels (currently email, with SMS planned for future releases).Please see the API Reference here for more information.
Currently only email message content is supported. SMS message content support is planned for future releases.
Communication Groups are primarily used within Tenant Automations to define the content that will be sent when an automation is triggered. A single Communication Group can be referenced by multiple automations, allowing you to reuse message templates across different automated workflows.
