Important notes About sent to multiple numbers:
1- All messages will be directly queued in your instance, ⚠️ so be very careful about setting the time between messages with the “Send Delay” parameter.
As in the picture:

The default value is 1 second
But it may not be suitable if the number of messages is large.
Therefore, it is very necessary to adjust this time well according to your project.
2- At any time, you can find out the number of messages in the queue from here:
