If you are sending an SMS to an extensive amount of contacts, you may want to consider batch sending to prevent overloading usage on your website.
To do so, you must turn on the advanced feature setting when sending an SMS. This is found below the SMS box.
Once clicked, the message below will appear. Edit this to your personal preference and click send SMS.
You can also enable ‘Quiet times’. This can be done in the ‘Settings’ section on the left side of your dashboard.
