# Active Subscriber Customer Tag

> Shopify customers are auto-tagged "Active Subscriber" while subscribed. Use the tag in Klaviyo, Locksmith, and Shopify Flow to segment and gate content.

Appfox Subscriptions automatically tags customers with **Active Subscriber** when they have an active subscription. This tag helps you segment customers for email campaigns, content gating, and other integrations.

## How it works

The **Active Subscriber** tag is managed automatically:

* **Tag is added** when a customer's subscription becomes active (when a new subscription is created as active, or when a paused subscription is resumed)
* **Tag stays** while the customer has at least one active subscription. Pausing, cancelling, or expiring one subscription leaves the tag in place when another subscription is still active
* **Tag is removed** only when the customer has no active subscription left. That happens when the last active subscription is paused, cancelled, or expires
* **Failed payments do not remove the tag** — customers keep the Active Subscriber tag while their subscription is in a failed billing state

The tag is applied and removed through Shopify's subscription webhooks. You don't need to enable or configure anything.

## Use it with other apps

The **Active Subscriber** tag appears in the customer's Shopify profile, so you can target it in other apps and integrations:

### Email marketing (Klaviyo, Mailchimp, etc.)

Create segments based on the **Active Subscriber** tag to:

* Send exclusive offers or early access to active subscribers
* Build win-back campaigns for customers who no longer have the tag
* Personalize email content based on subscription status

In Klaviyo, create a segment with the condition **Shopify Tags contains "Active Subscriber"**.

### Content gating (Locksmith, etc.)

Grant access to subscriber-only content, products, or collections by checking for the **Active Subscriber** tag.

#### Using Locksmith to gate content for subscribers

In Locksmith, create a lock on the pages, products, or collections you want to protect, then add a key with the condition that the customer has the **Active Subscriber** tag. Appfox removes the tag only when the customer has no active subscription left, so access continues while any subscription is still active and ends when the last one is paused, cancelled, or expires.

For a step-by-step walkthrough, see Locksmith's guide: [Use Locksmith and Appfox Subscriptions to grant access based on subscriptions](https://www.locksmith.guide/tutorials/more/use-locksmith-and-appfox-subscriptions-to-grant-access-based-on-subscriptions).

### Shopify Flow automations

Use the **Active Subscriber** tag as a condition in Shopify Flow workflows to trigger actions when customers become subscribers or when their subscription ends.

<Tip>
  The tag updates automatically when Shopify sends the subscription status change, usually within moments.
