New users can opt-in to receive messages and call from your business through the three following options:
- Keyword opt-in: for instance, “text START to 75486 to subscribe to our notification services.”
- Web opt-in: users sign up through a web form. They can subscribe to your notifications services while registering for an account through your website or by changing their notification preferences in the account settings.
- Paper opt-in: users sign up by filling out a paper form at a store/kiosk.
Similar to your terms and conditions page, carriers will look for specific language in the opt-in web form. We will need a link to your web form or a screenshot of this form 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 shortcode that will be used to send SMS messages.
- The frequency at which the end users will receive messages.
- A list of participating carriers.
For example, this is what the web page should contain:
Keywords are mandatory for all services delivered through a shortcode. 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:
Response: Thank you for subscribing to Plivo’s notification services. Reply HELP for more information. Reply STOP to cancel. Msg & data rates may apply. Msg freq may vary per user.
Response: You can email us at email@example.com. Reply STOP to cancel. Msg & data rates may apply. Msg freq may vary per user.
Response: You have been unsubscribed from xxx and will no longer receive messages. Reply HELP for help. Reply START to resume services.
