# Unsubscribe Functionality

To comply with best practices and regulations, marketing messages should include an unsubscribe option for recipients. This allows customers to easily opt out of future communications.

## Adding an Unsubscribe Link

You can add an unsubscribe link to your email templates by including the following tag:

```
${UNSUBSCRIBE_LINK}
```

This tag will be replaced with a unique link for each recipient. When a customer clicks the unsubscribe link, they will automatically be unsubscribed from all marketing messages.

> **Note:** The unsubscribe link should not be included in announcement-type messages, as these are intended for critical communications that are sent regardless of subscription status.

## Example Usage

```
If you no longer wish to receive these emails, you can <a href="${UNSUBSCRIBE_LINK}">unsubscribe here</a>.
```

## Behavior

- The unsubscribe link is unique to each recipient and message.
- Clicking the link immediately unsubscribes the customer from all marketing messages.
- No further confirmation is required from the customer.

## Best Practices

- Always include the unsubscribe link in marketing and newsletter messages.
- Do not include the unsubscribe link in announcement messages.
- Clearly label the unsubscribe option so customers can easily find it.
