Hey @raisonon, the best way to do this would be to provide all of the addresses in the To field, but also provide recipient variables through the headers field.

So, I think the best way to do this would be to keep a count and assign each of the recipients an “id” that you don’t even necessarily have to use.

Example:

$rcpt_vars = array();
$idx = 0;
foreach ($user_email_addresses as $user_addr) {
  $rcpt_vars[$user_addr] = array("batch_msg_id" => $idx);
  $idx++;
}

$rcpt_vars_json = json_encode($rcpt_vars);

wp_mail($user_email_addresses, $subject, $message, array(
  "X-Mailgun-Variables: ${rcpt_vars_json}"
));

Hope this helps! 🙂

With the 1.5.5 version, there was a change that was incompatible with PHP versions older than 5.5. I have fixed this in the 1.5.6 release, but I must also recommend that you upgrade your PHP version to at least 5.5.38 (old stable), although 5.6 or even 7.0 would be preferred, if possible. Older PHP versions may have security vulnerabilities and other incompatibilities with other software, which can cause big problems.

I hope the 1.5.6 release fixes your issue!

Hello! I’m pushing the 1.5.6 release today. It should be going out very shortly 🙂

What is your PHP version? Also, what other WordPress plugins do you have installed? What about PHP extensions?

Hi all, I think I’ve fixed the issue! Please try this beta release and let me know how it turns out!

Thanks!

@maguijo Are you able to update your PHP version to at least 5.5?

Hi @maguijo, what version of the plugin were you upgrading from? Also, what are your WordPress and PHP versions?

I have installed the WP Security plugin and enabled login page renaming, but could not replicate the bug.
