In Godaddy shared hosting . i am using PHPMailer to send HTML formatted mails, Mail is delivered but in html code not the html formatted mails .

$template = file_get_contents('otpmailcontent.txt', FILE_USE_INCLUDE_PATH);
$template = str_replace("###fullname###",$fullname,$template);
$template = str_replace("###otpcode###",$otp,$template);

$email=$toemail;//change email to receipents email
$mail = new PHPMailer();
$mail->SMTPDebug = 0; 
$mail->SMTPAuth = false;//SMTP authentication should be false
$mail->SMTPSecure = 'none';// Security type should be none 
 
$mail->Host = 'localhost';// SMTP host name should be localhost
$mail->Port = 25;  
 
$mail->setFrom('[email protected]', 'Signup OTP');     //Set who the message is to be sent from
 
$mail->addReplyTo('[email protected]', 'Signup OTP');  //Set an alternative reply-to address
$mail->addAddress($email);  // Add a recipient
$mail->WordWrap = 50;                                 // Set word wrap to 50 characters
                               // Set email format to HTML
$mail->Subject = 'Signup-OTP';
$mail->isHTML(true);   
$mail->Body = $template ;
$mail->AltBody = $body;
if(!$mail->send()) {
   echo 'Mailer Error: ' . $mail->ErrorInfo;
   echo 'Email Has not Sent';
   exit;
}
 else{
  echo "email sent";
}
}
