# Exclude customers by tag

Using Shopify Tags or BigCommerce Customer Groups you can remove a group of customers from participating or interacting with your loyalty program. This can be useful for customers you are rewarding in other ways, such as wholesaler discounts.

<Tip>
  **Tip:** To exclude an individual customer from participating your program, please review our guide on [excluding a single customer](/en/articles/4036235-exclude-a-customer).

## Exclude customers by Shopify Tag

To exclude customers from your program using Shopify Tags:

1. In Smile Admin, navigate to **Settings** > [**Platform**](https://app.smile.io/settings/platform).
2. In the **Exclude customers** card, click **Edit**.
3. Enter the Shopify customer tag(s) that you wish to exclude.
4. Click **Add**.
5. Click **Save**.

<Info>
  **Important:** Tags are case-sensitive, the tag needs to be entered exactly as it appears in Shopify. For example, if you enter **"Wholesale"** in Shopify, and **"wholesale"** in Smile, the tags won't match and the customers would not be excluded.
