Managing Blocklist

Last updated: 2021-05-31 16:05:42

    The blocklist feature offers a proactive way to block spam SMS messages. You can add mobile numbers to the blocklist, and the blocklisted numbers cannot receive messages sent with the corresponding signature. Up to 1,000 numbers can be blocklisted for all signatures.

    Prerequisites

    Before using the blocklist feature, you need to apply for an SMS signature and get it approved.

    Blocklisting Mobile Number

    1. Log in to the SMS Console.

    2. Select General Management > Blocklist Management on the left sidebar.

    3. Click Add Number.

    4. Select a signature and SMS message type and enter a mobile number.

      Note:

      If you need to add multiple numbers, separate them by pressing Enter (one number per row). Up to 1,000 numbers can be blocklisted for all signatures.

    5. Click OK.
      After successful addition, the configuration will take about 5 minutes to take effect. When the status of the number becomes effective, it will be unable to receive SMS messages sent with the corresponding signature.

    Querying Blocklisted Mobile Number

    1. Log in to the SMS Console.
    2. Select General Management > Blocklist Management on the left sidebar.
    3. Enter a mobile number and select the target signature at the top of the blocklist and click Query to check whether the number is in the current blocklist.

    Revoking Blocklisted Mobile Number

    Note:

    Removing a mobile number from the blocklist is irreversible, and the number can receive SMS messages sent with the corresponding signature normally.

    1. Log in to the SMS Console.
    2. Select General Management > Blocklist Management on the left sidebar.
    3. You can choose the removal operation as needed:
      • Single removal: click Remove in the row of the target mobile number.
      • Batch removal: select the numbers to be removed and click Batch Remove at the top of the blocklist.
    4. In the pop-up window, click OK.
