A: Hello! 👋

Thanks for the question.

At the moment we don't support sending mass messages to an outbound list. We may in the future but it also depends on your account how much of that you can do. There are strict limits and WhatsApp is obviously sensitive in such topics to reduce spam and unwanted messages.

Please see some of the constraints around message limits:

Hope this helps!

All the best,
Oscar
