Overview
AnEmailBroadcast sends an email to every contact in a ContactGroup, rendering the message from a referenced EmailTemplate. Use it to deliver a one-time message — such as an announcement or notice — to a defined audience within a Project.
A broadcast is immutable once created: if you need to change the message, schedule, or audience, delete the resource and create a new one. You can optionally defer delivery with scheduledAt; if omitted, the broadcast is sent as soon as the controller reconciles it.
