> On the left-side menu of a campaign, click Settings > Features, and enable or disable the following features:

> For the complete documentation index, see [llms.txt](https://docs.talon.one/llms.txt).

- **Achievements**
- **Coupons**
- **Giveaways**
- **Loyalty**
- **Referrals**
- **Strikethrough**

:::note
- You can only enable and disable features in campaigns created
[from scratch](/docs/product/campaigns/create-and-manage-campaigns.md#create-a-campaign-from-scratch).
- The **Giveaways** feature is not available in item campaigns.
- The **Strikethrough** feature is only available if you have connected a [cart item catalog](/docs/product/account/dev-tools/manage-cart-item-catalogs.md) to your Application.
:::

After you enable or disable the required features, click **Save Changes**.

## Enable campaign features

Enabling campaign features allow you to use extra
[conditions](/docs/product/rules/conditions/overview.md)
and [effects](/docs/product/rules/effects/overview.md).

For example, you can reward your customers with coupons via an effect after
you activate the **Coupons** feature.

:::important
We recommend only enabling features that you intend to use in a given campaign, as
the behavior of your campaigns may vary depending on which features are enabled.

For example, for performance reasons, the Rule Engine skips **Loyalty** campaigns when there
are no customer profiles in the session.
:::

## Disable campaign features

Disabling a campaign feature makes the conditions and effects related to the feature
unavailable in **new** rules. However, all rules created **before** disabling a given
feature still work as expected.

For example, customers can still receive loyalty points or redeem coupons after you
disable the **Loyalty** and **Coupons** features until you edit the rules accordingly.
