Your message was flagged as objectionable by the carrier. In order to protect their subscribers, many carriers have implemented content or spam filtering. Learn more about carrier filtering.
- Your users complained to their carrier that they were receiving unwanted messages.
- Carriers are filtering you based on content (objectionable keywords or links)
- Carriers are filtering you because the volume of messages you are sending from each standard long code phone number it too large.
- You are sending similar or identical content from a long code to many multiple numbers within a short period time.
- Your messages have been caught by the carrier filter for some unknown reason. Carriers do not advertise how their spam filters work to avoid reverse engineering.
- Be sure you have a good user experience and clear opt-out instructions.
- Avoid sending questionable content. See restricted message types below.
- Send fewer messages from each long code.
- The CTIA advises that each long code phone number should stay under 15-60 messages per minute and under 250 unique recipients a day.
- Wait a period of time before sending messages again. When most carriers blacklist numbers they have a cooling off period before they can send again.
Restricted SMS message types using TextP2P
TextP2P provides you with a platform to send and receive SMS messages to phone numbers around the world. However, TextP2P may suspend or close your project if you violate our Acceptable Use Policy or Terms of Service.
TextP2P’s Acceptable Use Policy (AUP) describes actions that are not permitted using TextP2P. TextP2P’s Terms of Service (ToS) describes the agreement between you and TextP2P regarding the use of TextP2P’s website and/or services.
Below is a list of highlights from the AUP of what practices are not allowed when sending and receiving SMS messages using TextP2P.
Please note: these guidelines do not replace nor cover all prohibited activities as covered by the TextP2P General Terms & Conditions, TextP2P Acceptable Use Policy or full TextP2P Terms of Service.
The following behaviors are not permitted on TextP2P:
Sending unsolicited messages
No one likes SPAM. You should only send SMS messages to recipients who have opted in to your service and are expecting communication from you. TextP2P actively monitors for this kind of activity and we may block the phone number or suspend your project if we receive complaints from your subscribers.
Sending harassing or abusive messages
Sending threats, unwanted messages and “SMS-bombing” – sending many messages to a single number without the recipient’s permission – are not allowed on TextP2P. You are responsible for ensuring that the users of your application do not send harassing or abusive messages.
Using TextP2P numbers to provide emergency services, such as 911-types of communication
Inbound and outbound communications between emergency service providers and end users are explicitly not permitted on TextP2P numbers. 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 use TextP2P 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 TextP2P’s notifications in conjunction with other public warning systems like sirens, radio and TV broadcasts if applicable.
Engaging in fraud, phishing or sending of sensitive data
TextP2P takes fraud and abuse very seriously.
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 customers over SMS.
Misrepresenting your identity (no spoofing)
Spoofing the SenderID 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 messages with pornographic or objectionable images
Do not send pictures that promote or potentially further any illegal activity or violate any legal or federal legislations or are likely to cause offense to recipients. These include but are not limited to pornographic or objectionable images.
