Please tell me, is the success rate of SMS group sending high? What are the restrictions?

The success rate of SMS group sending depends on many factors, including:

Whether the content of SMS is compliant: SMS with illegal content will be intercepted by operators, leading to failure.

Quality of SMS group sending platform: The platform quality is not high, which may lead to the failure of SMS sending.

Whether the mobile phone number is accurate: Inaccurate mobile phone number will also lead to the failure of SMS sending.

Whether the user's mobile phone is in arrears: the user's mobile phone is in arrears and cannot receive short messages.

Under normal circumstances, the success rate of SMS group sending is above 90%. If the SMS content is compliant, the platform quality is high, the mobile phone number is accurate, and the user's mobile phone is not in arrears, then the success rate of SMS group sending will be higher.

The restrictions of SMS group sending mainly include the following points:

SMS content restriction: SMS content cannot contain advertisements, violations of laws and regulations and other information.

SMS sending frequency limit: SMS sending frequency should not be too high, otherwise it will be intercepted by operators.

Limit on the number of SMS group sending: the number of SMS group sending should not be too many, otherwise it will be blacklisted by operators.

In order to improve the success rate of SMS group sending, it is suggested to follow the following points:

Use compatible SMS content to avoid content interception.

Use an accurate mobile phone number to avoid sending short messages.
