You need to initialize the object, Magento\Newsletter\Model\SubscriberFactory to add a subscriber. You can also add the subscriber by any email.

Follow example below to set magento 2 subscriber programmatically

/**
* @var \Magento\Newsletter\Model\SubscriberFactory
*/
protected $subscriberFactory;

public function __construct(
   ...
   \Magento\Newsletter\Model\SubscriberFactory $subscriberFactory,
   ...
)
{
   ...
   $this->subscriberFactory = $subscriberFactory;
   ...
}

public function execute()
{
   $email = 'example@gmail.com';
   $this->subscriberFactory->create()->subscribe($email); // Subscribes by email
   
   // Load email and update status
   $subscriber = $this->subscriber->create()->loadByEmail($email);      $subscriber->setStatus(\Magento\Newsletter\Model\Subscriber::STATUS_UNSUBSCRIBED);
    $subscriber->save();
}
