How does the reliability and speed of email sending differ between using the PHP mail function and phpMailer on web hosting platforms like 1&1?

The PHP mail function is often less reliable and slower compared to using phpMailer on web hosting platforms like 1&1. phpMailer offers more advanced features and better error handling, resulting in more reliable email sending. To improve reliability and speed, it is recommended to use phpMailer for sending emails on web hosting platforms like 1&1. 

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

$mail = new PHPMailer(true);

try {
    $mail->isSMTP();
    $mail->Host = 'smtp.example.com';
    $mail->SMTPAuth = true;
    $mail->Username = 'your@example.com';
    $mail->Password = 'your_password';
    $mail->SMTPSecure = 'tls';
    $mail->Port = 587;

    $mail->setFrom('from@example.com', 'Your Name');
    $mail->addAddress('recipient@example.com', 'Recipient Name');

    $mail->isHTML(true);
    $mail->Subject = 'Subject';
    $mail->Body    = 'Email body';

    $mail->send();
    echo 'Email has been sent';
} catch (Exception $e) {
