If you send a Marketing template to a customer while a Service conversation is still open, Meta will open a new Marketing conversation and charge your account for it—even though the Service window is active.

5 | Agent sends a Marketing template (e.g., “20% off offer”) | Opens a Marketing conversation | ✅ Yes |
