Sendgrid-php: How to send bulk email to user

[iamanupammaity]

require 'sendgrid-php/sendgrid-php.php';
$email_subject = 'Test email subject';
$email_body = '<p><strong>Hi </strong></p><p>This is a test email.</p>';
$email = new \SendGrid\Mail\Mail(); 
$email->setFrom("[email protected]", "example");
$email->setSubject($email_subject);
$email->addTo('[email protected]');
$email->addContent(
  "text/html", $email_body
);
$api_key = 'XXX-XXXX-XXX';
$sendgrid = new \SendGrid($api_key);
try {
  $response = $sendgrid->send($email);
  print $response->statusCode() . "\n";
  print_r($response->headers());
  print $response->body() . "\n";
} catch (Exception $e) {
  echo 'Caught exception: '. $e->getMessage() ."\n";
}

This code is working fine but when I am removing "to" field and entering all email id into "bcc", I am receiving an error saying that "to" field is mandatory. I want to send bulk email to everyone in bcc so that they can't see the email id of other members.

Please help how to do it.

Thanks, it's worked.

The code is elegant.

One more question. What is the number of recipients I can send the email in a loop??
