What ways can users opt in to receiving messages?

New users can opt in to receive messages and calls from your business through any of these three options: 

  • Keyword opt-in: for instance, “text START to 75486 to subscribe to our notification services”
  • Web opt-in: Signup through a web form. Users can subscribe to your notification services while registering for an account or by changing their notification preferences in the account settings.
  • Paper opt-in: Signup by filling out a paper form at a store or kiosk. 

Web opt-in

As they do with your terms and conditions page, carriers look for specific language in opt-in web forms. Plivo needs a link to your web form or a screenshot of it to submit your application. If you use a web form, it must include the following language: 

  • Opt-out and help keywords in BOLD letters
  • The short code that will be used to send SMS messages
  • The frequency at which the end users will receive messages
  • A list of participating carriers
  • Links to the terms and conditions and privacy policy pages

For example:

You will receive up to five messages per day. Message and data rates may apply. Text HELP to 75486 for help. Text STOP to 75486 to cancel. Supported carriers: AT&T, Boost Mobile, T-Mobile, Metro by T-Mobile, Verizon Wireless, Sprint, UScellular, and Virgin Mobile. See our SMS Terms of Service and Privacy Policy.


Keyword opt-in 

Keywords are mandatory for all services delivered through a short code. Your messaging service must support keywords that trigger opt-in, opt-out, and help commands. When a user texts any of the supported keywords, the service must have an auto-response that contains specific language around messaging frequency and messaging rates.

Here are a few examples: 

Keyword: START

Response: Thank you for subscribing. Reply HELP for more information. Reply STOP to cancel. Message and data rates may apply. Message frequency may vary per user. 

Keyword: HELP

Response:  You can email us at support@plivo.com. Reply STOP to cancel. Message and data rates may apply. Message frequency may vary per user.

Keyword: STOP

Response:  You have been unsubscribed from xxx and will no longer receive messages. Reply HELP for help. Reply START to resume services.
