When to send this email
Send first to a consented waitlist or past clients when appropriate, then to the broader audience at the announced opening time. Coordinate every channel with live slot inventory.
Workflow trigger: The event economics, location, permit, schedule, agreement, payment, booking page, reminders, weather plan, and fulfillment capacity have passed a complete test.
Need more than one announcement? Generate a coordinated mini-session launch kit with a client email, social caption, availability update, and waitlist message, then replace the placeholders before sending.
