Step 1:
Go to Lightspeed Settings>Custom Fields
Step 2:
Click New Field in the top right corner. The custom field name should be 'Do Not Text' and you'll want it associated with the customer.
Step 3:
When you click continue, you'll be asked what field you want. Choose Checkbox, and do not default to checked.
If you default to checked, then no one will get messages unless you go in and uncheck it.
You'll then create the field.
Step 4:
Once you create the field, refresh Lightspeed. Now within all customer profiles you'll see this field. For customers you don't want to receive these messages, simply check the box and it will prevent messages from being sent.
