What is the reason for the failure of sending backup information?

Short message marketing has become a new marketing method with the advantages of accurate delivery, high arrival rate and low cost. Many people have used SMS platform, but in practice, many people will encounter the situation that their hard-edited SMS content can't be sent out/failed. What is the reason?

1, the information content or signature has not been audited, and the operator stipulates that when sending a short message, the signature and content of the short message must be reported, and it can not be sent until it is approved.

There is something wrong with the number. No number, downtime, blacklist, etc. And you can't get a text message at this number.

3. If the content contains forbidden words, sensitive words or illegal content, it will be intercepted by the operator system, and the direct SMS transmission will fail.

4. The format is incorrect. When sending, I forgot to sign and unsubscribe, or some of my signatures were incorrect. The correct short message format should be short message signature+text, in which the symbols should be in Chinese mode. If special characters appear in the signature, the sending will also fail.

5. There are restrictions on the number of times users send short messages, such as IP restrictions and the total number of mobile phone numbers received in a single day.

6. The submitted number is blacklisted. In this case, the other party needs to confirm the cancellation of the blacklist with Unicom, mobile and telecom operators.

7. Operators in some areas are blocked. Blocking this area will also cause the mobile phone not to receive SMS.

8, system, network and other issues.

There are many reasons for the failure of sending short messages, which may be that the receiver's mobile phone is down or the signal is not good, or the content or signature of the short message is wrong, or of course the channel quality of the short message platform. For enterprises, it is necessary to carefully select third-party service providers, and comprehensively evaluate whether they provide direct access for SMS operators, whether they have backup sms channel, and whether the SMS interface is stable. , and screen the empty number and test the content of the short message before sending the short message in groups.
