Sending threats, unwanted messages and “SMS-bombing” – sending many messages to a single number without the recipient’s permission – are not allowed.

1st Responder Communications

Inbound and outbound communications between emergency service providers and end users are explicitly not permitted on the SMS API. SMS notifications can be used to provide information during an emergency, but should not be used as a replacement for or a means to contacting actual emergency services. It is acceptable to send notifications that do not directly impact life safety. For example, early warning alerts, safety advisories, event cancellations, etc. are allowed. We recommend building in redundancy for important applications and using notifications in conjunction with other public warning systems like sirens, radio and TV broadcasts if applicable. SMS is bandwidth dependant. If you want to alert 1 million people that there are snakes on the plane it will take a an hour or so.

Fraud, Phishing or Sending of Sensitive Data fraud and abuse very seriously. Report it to Sending messages with fraudulent information or phishing to request confidential information from subscribers is not allowed. It’s also never a good idea to provide financial information or any other sensitive personal information to your subscribers over SMS.

Misrepresenting your Identity or Spoofing

Spoofing or otherwise attempting to mislead message recipients as to who is sending the SMS message is not allowed. It’s good business sense to identify your brand or name in each message you send. But it’s not ok to identify yourself as another individual or business.

Sending Inappropriate Images

Do not send pictures that promote or potentially further any illegal activity or violate any legal or State and Federal legislation or are likely to cause offense to recipients. These include but are not limited to pornographic or objectionable images.
