# Add Subscriber

## `array addSubscriber(array $subscriber [, array $list_ids = [], array $options = []])`

This method allows to create a subscriber, add them into lists and handles confirmation email and admin notification email sending and welcome email scheduling.

If sign-up confirmation is enabled in the MailPoet settings a subscriber is created with status `unconfirmed` otherwise the status is set to `subscribed`.

*A confirmation email* is an email which is sent to a subscriber so that they can confirm his subscription. It is sent only if sign-up confirmation is enabled in the MailPoet settings.
*A welcome email* is an automatic email which is sent to a new subscriber. This email is scheduled only if sign-up confirmation is disabled and some welcome email is configured for some of given lists. In case of required sign-up confirmation it is scheduled later after a subscriber confirms the subscription.
*An admin notification email* is sent to the site admin to inform they about a new subscription. It is sent only if the notification feature is enabled in the MailPoet setting.
All these emails can be disabled using `$options`.

A subscriber can be added only once. This method throws an `\Exception` in case of adding an existing subscriber.
This method throws also an `\Exception` in case that some of `$list_ids` is invalid. In such a case subscriber is created but is not subscribed to any list.
There might be other `\Exceptions` because of some invalid input data such a invalid email address etc.

It returns a new subscriber. See [Get Subscriber](GetSubscriber.md) for a subscriber data structure.
