Forbidden Use Cases

Certain types of messages are not allowed, and we take these restrictions seriously to maintain a safe and reliable messaging environment for all users. It is essential to refrain from engaging in the following activities listed in the table below. Please note that these forbidden use cases are not only related to the content of the message but the business type itself.Additional Restrictions Even if your specific use case is not listed as prohibited, certain message content may still be subject to restrictions. For instance, the use of shared or free public URL shorteners is not permitted and will lead to filtering. Ensure that when using a shortened URL it is company-branded.

Forbidden message categories for SMS/MMS in the US/Canada

My use case is listed as forbidden. What can I do?

If your use case is listed above as forbidden for SMS and MMS messaging in the US, you may be able to use another Twilio product to reach your recipients.The Salesmate Sendgrid Email API (Send all your marketing and transactional email through our platform with a proprietary mail transfer agent and infrastructure for scalable delivery.) is an option for many of the above use cases. For example, cannabis- or CBD-related messaging may be conducted via email, as long as you have proper age gating (requiring a date of birth from website users) in place and are sending toward recipients in a locale where the substance is legal. In addition, the Salesmate Programmable Voice product is not subject to the same carrier restrictions as SMS.For more information about cannabis-related messaging alternatives, see Can I send cannabis or CBD-related messaging traffic on Twilio?
