I am sending email with the wp_mail() function but it is not working. It is returning false. Also it is not giving any error in the server log.

This is my code:

         $mailResult = false;
         $to = "tayyabvohra@gmail.com";
         $subject = "HUDPowerBid Mailgun Test exec on ";
         $message = "Testing Mailgun at: ";
         $mailResult = wp_mail( $to, $subject, $message, $headers);
         $myarr= array('error' => true, 'mail' => $mailResult);

I have also tried with the above code and below code also I have tried with these two codes at once but nothing is working

    $to1 = 'abc@gmail.com';
    $subject1 = 'Post Published by Author';
    $headers1 = 'From: admin <admin@urdutahzeeb.com>' . "\r\n";  
    $message1 = 'your';

        $a=wp_mail($to1, $subject1, $message1, $headers1);
        echo json_encode($my);
  • Have you tried PHP mail with the same headers? Perhaps your mail host has some limitations on what you can do.

  • remove ."\r\n" from $headers1.

Although wp_mail returns false on failure, it does also contain an action hook to allow you access to error information.

If phpmailer fails to send, these lines run:

         * Fires after a phpmailerException is caught.
         * @since 4.4.0
         * @param WP_Error $error A WP_Error object with the phpmailerException message, and an array
         *                        containing the mail recipient, subject, message, headers, and attachments.
        do_action( 'wp_mail_failed', new WP_Error( 'wp_mail_failed', $e->getMessage(), $mail_error_data ) );

        return false;

If you attach a function to wp_mail_failed you can look at the WP_Error object to get more info on your problem.

  • @butlerblog Thanks for your edit, but my use of the word "does" is deliberate emphasis so I've rolled it back. Apr 12, 2019 at 12:31
