A one-time campaign sends a single message — an email, an in-app notification, or both — to the audience you choose. The mobile app uses the same six-step campaign builder as the web app: choose the campaign type, audience, schedule, channels, content, and final review.
Before you start: sign in with an employer/operator account that can manage marketing. A saved segment is the fastest audience option, but you can also build a custom audience from contact rules inside the wizard.
