What is opt-in and opt-out?

Opt-in example:

When customers complete a contact form on the website, they are asked if they agree to receive text messages to the phone number they provided. They can check a box to indicate they agree.

“I agree to receive text messages from Unus Transportation & Services LLC, 202 280 2081 at the phone number provided above. Message frequency varies and will include [Types of messages: appointment reminders, order updates, etc.]. Reply STOP to opt-out or HELP to get help. We never share your mobile opt-in information with anyone."

Opt-out example:

In addition to the checkbox agreeing to receive messages, there should be a checkbox customers can select if they don’t want to receive messages.

“I do not wish to receive text messages from Unus Transportation & Services LLC”.
