# Subscribe/Unsubscribe

Subscribe/Unsubscribe card utility card allows you to subscribe or unsubscribe a customer to or from a specific segment. Segments are predefined categories that you can use to group your customers based on their consent or opt-in status. You can use segments to ensure that you only send messages to customers who have given you permission to do so.

## Using Subscribe/Unsubscribe

### Select segment

* You need to select the segment that you want to add or remove customers from. A segment is a group of customers that share a common attribute, behavior, or status. You can choose from the existing segments that you have created and used before. 

For example, you can select or create a segment like “Newsletter Subscribers”, “Loyal Customers”, “Interested in Shoes”, etc.

### Create new segment

*  To create a new segment, you need to click on the button ‘create new segment here’ and enter the name of the segment in the pop-up window. It'll then redirect you to the 'segment tab' where you need to add filters, and automatically, the related contacts are selected. Get complete steps guidance for the same by tapping below.

For example, you can create a new segment like “Birthday Month” with the description “Customers who have their birthday in the current month”.

### Action

* You need to choose the action that you want to perform with the segment that you have selected. 
*  Subscribing customers means that you will add them to the segment and send them messages related to the segment. 
* Unsubscribing customers means that you will remove them from the segment and stop sending them messages related to the segment. 

For example, you can choose to subscribe customers to the segment “Birthday Month” and send them a special offer or a greeting on their birthday.
