Hi, @Suff22886!
Is this broadcast being done with WhatsApp, Instagram or Messenger?
Each channel has its own particularities to broadcast. And the main one is the 24h Window Rule.
And if you're trying to send something outside the 24h Window Rule, you have to:
- WhatsApp: Create message templates and send it as the first message of your flow (this has extra costs).
- Messenger (Facebook): You need to invite you contacts to a DM List before being able to send something to them outside the 24h window.
- Instagram: In the past you could enter to a beta test to Instagram DM Lists, but it was put on hold and never came back to new accounts. Sadly, this means that for IG, there's no way to contact your audience outside the 24h Window.
Hope this helps somehow.
