You can also choose what messages are send and what is the delay between them. You can also choose what messages are send and what is the delay (sleep_time is only used for multiple messages) between them.
If you are sending a grouped message and you want to delay the execution of the script you need to use the ```random_delay``` variable which is set to 30 by default.
This is the default configuration: This is the default configuration:
