Broadcasts send one message to many partnered creators at once: scoped to a campaign, a project, or your whole org. (Applicants can't be broadcast to: only creators you've partnered with.)
Before sending you see the full recipient list and can toggle individuals off. Messages support first-name and last-name personalization variables, up to 1,000 characters, and up to 3 images or 3 files.
Each recipient gets it as a normal direct message. A cooldown applies between broadcasts to the same audience, so batch your announcements.
