# Email subscription

The Batch Android SDK allows you to:

* Add and remove email address from a user profile. The profile will automatically be created if needed.
* Edit a profile's marketing subscription.

{% hint style="info" %}
In order to set an email address and subscription status on a profile, the creation of a project is required. If no project is set up, any calls made for these actions will be ignored.
{% endhint %}

Here is how to set an email with a marketing subscription:

{% tabs %}
{% tab title="Kotlin" %}

```kotlin
// This requires to have a custom user ID registered 
// by calling the `identify` method beforehand.
Batch.Profile.editor().apply {
  setEmailAddress("john.doe@batch.com") // Null to erase. Addresses must be valid.
  setEmailMarketingSubscription(BatchEmailSubscriptionState.SUBSCRIBED) // or BatchEmailSubscriptionState.UNSUBSCRIBED
  save()
}
```

{% endtab %}

{% tab title="Java" %}

```java
// This requires to have a custom user ID registered 
// by calling the `identify` method beforehand.
Batch.Profile.editor()
  .setEmailAddress("john.doe@batch.com") // Null to erase. Addresses must be valid.
  .setEmailMarketingSubscription(BatchEmailSubscriptionState.SUBSCRIBED) // or BatchEmailSubscriptionState.UNSUBSCRIBED
  .save();
```

{% endtab %}
{% endtabs %}
