Running a multi website and store setup.

Website - Japan
Store - JP
Store View - JP


I'm trying to import newsletter subscribers from a CSV.

I'm using the following code in a file called **import.php** that I run from the root dir. eg: dev.xyz.com/import.php and the subscribers.csv is also in the root dir.

    <?php
      
    use Magento\Framework\App\Bootstrap;
    require __DIR__ . '/app/bootstrap.php';
    $store_id = 1;
    $csv_filepath = "subscribers.csv";
    $csv_delimiter = ',';
    $csv_enclosure = '"';
    $magento_path = __DIR__;
    
    $params = $_SERVER;
    
    $bootstrap = Bootstrap::create(BP, $params);
    
    $obj = $bootstrap->getObjectManager();
    
    $state = $obj->get('Magento\Framework\App\State');
    $state->setAreaCode('frontend');
    
    $websiteId =  $obj->get('Magento\Store\Model\StoreManagerInterface')
        ->getStore()
        ->getWebsiteId();
    
    $customerAccountManagement =$obj
        ->create('Magento\Customer\Api\AccountManagementInterface');
    
    $_subscriberFactory = $obj->create('Magento\Newsletter\Model\SubscriberFactory');
    
    
    if (($handle = fopen("subscribers.csv", "r")) !== FALSE) {
        while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
            // email Id
            $emailId = $data[0];
           /* customer */
            if($customerAccountManagement->isEmailAvailable($emailId , $websiteId)){
                echo $emailId ."Guest <br/>";
                $_subscriberFactory = $_subscriberFactory->create()->subscribe($emailId );
            }else{
                echo $emailId ."Register <br/>";
                $customerFactory = $obj->get('Magento\Customer\Model\CustomerFactory');
                $customer=$customerFactory->create();
                $customer->setWebsiteId($websiteId);
                $customer->loadByEmail($emailId );// load customer by email address
                if($customer->getId()){
                    $_subscriberFactory->create()->subscribeCustomerById($customer->getId());
                }
    
            }
        }
        fclose($handle);
    }

CSV Headers/Column names as follows:

**ID | Email |	Type |	Customer First Name |	Customer Last Name |	Status |	Website	Store |	Store View**

But I get the following error

    IDGuest
    
    Warning: Cannot modify header information - headers already sent by (output started at /home/xyz/dev.xyz.com/import.php:36) in /home/xyz/dev.xyz.com/vendor/magento/framework/Stdlib/Cookie/PhpCookieManager.php on line 148

How can I import newsletter subscribers from a CSV? 

Thanks in advance.

UPDATE

Changed code as suggested by Rajesh Hothi

Now I get the following error

    IDGuest
    
    Fatal error: Uncaught Exception: The input is not a valid email address. Use the basic format local-part@hostname in /home/xyz/dev.xyz.com/vendor/magento/module-newsletter/Model/Subscriber.php:501 Stack trace: #0 /home/xyz/dev.xyz.com/import.php(37): Magento\Newsletter\Model\Subscriber->subscribe('ID') #1 {main} thrown in /home/xyz/dev.xyz.com/vendor/magento/module-newsletter/Model/Subscriber.php on line 501


Format of CSV file shown below.

It imports one line in which the email ID doesn't show and its not in the order of the csv file, as below.
