# Using HTML to Add Opt-In/Opt-Out Links in ELS/Emails

You can include HTML links in an email to give consumers the option to opt in or opt out of receiving messages.

When a consumer clicks either link, the action applies only to the email address that received the message.

#### Opt-in Link

The **opt-in** link allows the consumer to consent to receiving future messages at their email address:

```xml
<a href="${primaryDemographicEmail.optInUrl}">Opt In</a>
```

#### Opt-out Link

The **opt-out** link allows the consumer to unsubscribe from future messages at their email address:

```xml
<a href="${primaryDemographicEmail.optOutUrl}">Opt Out</a>
```
