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
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.
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
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).
A compliant text message opt in form typically includes:
Phone number field
Consent checkbox (not pre-checked)
Message frequency disclosure
Brand identification
Terms and privacy link
STOP opt-out instructions
Using clear text message opt in language improves delivery rates for messaging campaigns and compliance with SMS carriers. To be compliant when sending online text messages, recipients must be able to opt-out or be removed from the anytime they wish to do so from the SMS subscriber list.
Businesses should use opt in for text messages before sending:
Marketing promotions
Delivery notifications
Event notifications
US carriers and messaging regulations require consent before sending application-to-person (A2P) SMS messages.
To meet US carrier standards and messaging regulations (including 10DLC registration where applicable), businesses should follow:
Clear Consent: Customers must actively opt in.
Brand Transparency: Clearly identify the sending business.
Message Disclosure: Explain message frequency and purpose.
Record Keeping: Store proof of opt in to text messaging.
Easy Opt-Out: STOP or Opt-out must unsubscribe immediately.
Strong opt in language for text messages should include:
Business name
Message purpose
Frequency disclosure
STOP opt-out instruction
HELP support instruction
Example compliant text message opt in language:
“By texting JOIN, you consent to receive recurring automated marketing SMS from [Business Name]. Msg frequency varies. Msg & data rates may apply. Reply STOP to opt out. Reply HELP for help.”
Using clear and compliant opt-in text message examples for business helps businesses build higher-quality subscriber lists and improve campaign performance.
