Manage SMS subscriptions

The customer's subscription status for the SMS channel is captured in a unique attribute. 

If you are using Blueshift’s full service SMS offering, you can use multiple sender IDs for your SMS campaigns and manage your customer's preferences individually for each sender ID.

Single sender ID

The customer subscription status is managed using the unsubscribed_sms and unsubscribe_sms_at attributes. When a customer is added to Blueshift, if no data is provided for the customer's subscription status, the unsubscribed attribute for the customer is set to NULL.

Note: The unsubscribed attribute is not available for the multiple sender ID model.

You can view this attribute in the customer profile in the Channel Preferences section.

Multiple sender IDs

You can use multiple sender IDs for your SMS marketing campaigns without ever having to worry about compliance. If you use different sender IDs for different purposes like deal alerts, general marketing updates, order and shipping updates, and so on, you can manage the customer subscription preferences individually for each sender ID.

Attribute model for multiple sender IDs

SMS subscription for multiple sender IDs is managed using the sms_preferences attribute.

The following example shows the sms_preferences for two different sender IDs.

"sms_preferences": [ 
{
 "sender_id": "10907", 
 "subscribed": false, 
 "unsubscribed_at": "2023-07-02T18:45:31.869574Z", 
 "subscribed_at": "2023-05-18T05:33:31.869574Z"
}, 
{
 "sender_id": "8530", 
 "subscribed": true, 
 "subscribed_at": "2022-05-21T08:45:31.869574Z" 
}]

You can view this attribute in the customer profile in the SMS Preferences section. All sender IDs available for your account are listed along with the individual subscription status.
