Ich benutze die folgende phpmailer-Funktion, um mehr als 1000 Mails zu verschicken

<?php
function sendMail($sendTo,$Subject,$Body){

    require_once 'PHPMailer/PHPMailerAutoload.php';

    $mail = new PHPMailer;
    $mail->isSMTP();                                      
    $mail->Host = 'smtp.example.com;smtp.example.com';  
    $mail->SMTPAuth = true;                               
    $mail->Username = '[email protected]';           
    $mail->Password = 'password';                         
    $mail->SMTPSecure = 'ssl';                            
    $mail->Port = 465;                                    
    $mail->From = '[email protected]';
    $mail->FromName = 'xyz';
    $mail->WordWrap = 50;                                 
    $mail->isHTML(true);                                  

    $mail->addAddress($sendTo);               
    $mail->Subject = $Subject;
    $mail->Body = ( stripslashes( $Body ) );
    $mail->AltBody = 'Please Use a Html email Client To view This Message!!';

    if(!$mail->send()) {
        $return = 'Message could not be sent.';
        // echo 'Mailer Error: ' . $mail->ErrorInfo;
    } else {
        $return = 'Message has been sent!';
    }
    return $return;
}

und das ist der Code, den ich benutze, um die Funktion aufzurufen

foreach ($emails as $email) {
 $subject = "sample subject";
 $body = "sample body";
 sendMail($email, $subject, $body);
}

size of $ emails array is 1000+ Gibt es eine schnellere und bessere Möglichkeit, dies zu tun?
