What are the differences between using IsMail and IsSMTP in PHPMailer for sending emails?

When sending emails using PHPMailer, the main difference between using IsMail and IsSMTP is the method of sending the email. IsMail uses the local mail server to send the email, while IsSMTP allows you to specify an external SMTP server for sending emails. If you are experiencing issues with sending emails using IsMail, you may want to try switching to IsSMTP and provide the necessary SMTP server settings for successful email delivery. 

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

$mail = new PHPMailer();

// Using IsSMTP to send emails
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your_username';
$mail->Password = 'your_password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

// Set email parameters
$mail->setFrom('from@example.com', 'Sender Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Subject of the email';
$mail->Body = 'Body of the email';

// Send the email
if ($mail->send()) {
    echo 'Email sent successfully';
} else {
    echo 'Email could not be sent. Mailer Error: ' . $mail->ErrorInfo;
}
