I have an email system that I am making in a WordPress plugin to send the emails with this code:


$email = new PHPMailer();

$email->From      = get_option('admin_email');
$email->FromName  = 'my name';
$email->Subject   = $subject;
$email->Body      = $body;

foreach($emails as $mail) {
    if(is_email($mail)) {
if($name) {
    $att = PLUGIN_DIR.'uploads/'.date('Ymd').'_'.$name;

// check if email is sent or not
if(!$email->Send()) {
    echo "Message was not sent <br />PHPMailer Error: " . $email->ErrorInfo;
else {
    echo "Message has been sent";
    $_POST = array();

This works great. Tested it online and sends to all the tested emails.

Can I make it like this? I mean, with phpmailer class not native to WP. Is this wrong? Is it best to use native WP phpmailer? If so, how can I do it?

Thanks in advance.

  • WordPress already uses PHPMailer under hood - what do you expect from implementing this on your own? Just use wp_mail() and don't worry

    You didn't mention email volume; if more than "nominal" then consider using a separate SMTP service; there are plenty of good SMTP mailer plugins for WP. Getting consistent successful email delivery is part art and part science.

  • You may as well use the built in one. its basically PHP Mailer built into the core.

WordPress offers its own mailing system. I suggest you use that instead of PHP's native mail.

wp_mail accepts five arguments:

wp_mail( $to, $subject, $message, $headers, $attachments );

So your code can be written this way:

// Set the headers
$headers[] = 'From: ' . get_option('admin_email');
// Add the addresses to an array
foreach($emails as $mail) {
    if(is_email($mail)) {
        $to[] = $mail;
// Add the attachment
if($name) {
    $att[] = PLUGIN_DIR.'uploads/'.date('Ymd').'_'.$name;
// Send the emails
$results = wp_mail( $to, $subject, $body, $headers, $att );
// Output the results
echo $results;

Simple and short.
