NoteThe actual content sent is not affected by the task name.
SMS Platform: Select an SMS platform from the drop-down list.
SMS Type: Select SMS Notification.
Signature Selection: Select an existing signature, Create Signature, or Add Signature from the drop-down list. The signature will be sent to the user along with the text message.
When you add an approved signature, you do not need to add []. The signature will be sent with the [] symbol to avoid duplication.
NoteYou can add a signature only after the signature is approved by the corresponding SMS platform. Otherwise, the SMS message fails to be sent. Check whether the signature is approved in the Alibaba Cloud SMS Console or on a third-party SMS platform. For more information about how to create a signature, see SMS Signature Management.
Select a template:
Select Existing Template: Select an existing template from the drop-down list. For more information, see Create Text SMS Template.

Short Link:
To use a short chain, select an existing short chain from the drop-down list or Create Short Chain, and click Copy Short Chain. Then, use the Ctrl + V keys to paste the copied short chain to the message content. Format: http://xxx.cn/xxxxxx.
If you want to use a short chain with a short parameter and select With Short, the copied short chain will contain the short parameter. Specify this parameter in the following format: http://xxx.cn/xxxxxx?ph=${sp_xxxx}.
NoteWhen selecting a short chain, please pay attention to the validity period of the short chain. When the user clicks on the short chain, the short chain must be within the validity period to open the URL normally.
${sp_xxxx} in a short chain with a short parameter is a short parameter. When a short message is sent, a corresponding short parameter is generated based on each mobile phone number to collect user short chain click data.
In Alibaba Cloud short chain, the user short chain click data collected by using short parameters is returned to Alibaba Cloud SMS Platform. Contact the customer service personnel of this service to obtain the data. In general short chain, the user short chain click data collected by using short parameters is returned to Quick Audience for analysis.

NoteIf you continue to change the content after you select a template, it is equivalent to creating a new template. You must also approve the template before you can send it.
