Opt-In Text Message Examples

Businesses using SMS marketing must obtain clear customer consent before sending messages. This is done through opt-in text messaging, which helps businesses stay compliant, build trust, and improve engagement rates. 

Using the right opt in text messages helps businesses grow subscriber lists while messaging compliance standards. 

This guide focuses on opt-in text message examples for business, while also explaining: 

  • What is a text message opt-in keyword 

  • What does opt mean in text message 

  • What is an SMS opt-in form 

  • When businesses should use opt-in text messages 

  • SMS opt-in requirements for business messaging 

What Does Opt Mean in Text Message? 

Many businesses ask what does opt mean in text message or what is opt in text message. 

In SMS marketing, “opt” means “to choose to participate”. 

  • Opt in text message → Customer agrees to receive texts 

  • Opt out → Customer stops receiving texts 

When customers send a text message opt in, they are giving documented permission for businesses to message them. 

 

What Is a Text Message Opt-In Keyword?

A text message opt-in keyword is a word customers text to a business number to subscribe to SMS messages. 

Common opt in text messaging keywords include: 

  • JOIN 

  • YES 

  • START 

  • SUBSCRIBE 

  • DEALS 

  • VIP 

  • ALERTS 

What Is an SMS Opt-In Form?

A text message opt-in form is where customers submit their phone number and provide express written consent to receive SMS messages. 

In the United States, SMS consent and marketing compliance are regulated and enforced under the Telephone Consumer Protection Act (TCPA) and monitored by the Federal Communications Commission (FCC), with enforcement actions also supported by the Federal Trade Commission (FTC).
