      We are using the Bulk Mailer addon. It worked for the first time but not working right now.

      Here is the log output

      [09/02/2023 10:04:13] Mailgun returned an error: Your credentials are incorrect.

      Hi MM,

      Thanks for reaching out. The logs show that messages were sent successfully on 22/02/2023 04:23:48, but then started failing due to an error from Mailgun. I’ll look into the code as to why the error message is not showing, but this indicates that you should contact Mailgun support to see why they’re blocking the send.

      Cheers,
      Vinny

      This did not fix yet.

      From Mailgun support

      Your account is currently active so if you need help with sending with the API, here is some information that should help you in sending:
      
      https://documentation.mailgun.com/en/latest/user_manual.html#sending-via-api
      
      Sending a plain text message:
      
      curl -s --user 'api:YOUR_API_KEY' \ https://api.mailgun.net/v3/YOUR_DOMAIN_NAME/messages \ -F from='Excited User <mailgun@YOUR_DOMAIN_NAME>' \ -F to=YOU@YOUR_DOMAIN_NAME \ -F [email protected] \ -F subject='Hello' \ -F text='Testing some Mailgun awesomeness!'

      Please advise.

      To confirm. I have tested the API as they have suggested and it works well.

      [code]
      add_shortcode( ‘test_mailgun_api’, function(){
      $apiKey = ‘f51eXXXXXXXXXXXXXXXXXXXX-d1a07e51-b785537c’;
      $domain = ‘mg.domain.org’;
      $from = ‘Excited User <[email protected]>’;
      $to = ‘[email protected]’;
      $to2 = ‘[email protected]’;
      $subject = ‘Hello’;
      $text = ‘Testing some Mailgun awesomeness!’;

      $url = “https://api.mailgun.net/v3/$domain/messages&#8221;;

      $ch = curl_init();

      curl_setopt($ch, CURLOPT_URL, $url);
      curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
      curl_setopt($ch, CURLOPT_USERPWD, ‘api:’ . $apiKey);
      curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
      curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
      curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
      curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
      curl_setopt($ch, CURLOPT_POST, true);
      curl_setopt($ch, CURLOPT_POSTFIELDS, [
      ‘from’ => $from,
      ‘to’ => $to,
      ‘to’ => $to2,
      ‘subject’ => $subject,
      ‘text’ => $text,
      ]);

      $result = curl_exec($ch);
      ob_start();
      if (curl_errno($ch)) {
      echo ‘Error:’ . curl_error($ch);
      } else {
      echo ‘Mail sent successfully’;
      }

      curl_close($ch);
      return ob_get_clean();
      });
      [/code]

      Hi MM,

      That response from support is not helpful. Please check the Mailgun logs the next time it fails for relevant information about the failures.

      That’s the problem. I don’t see any error details on the log. It just shows “Mailgun returned an error: ” plus there’s nothing shown in log at Mailgun dashboard.
