License Expiry Email Disable or Configurable

You can prevent a mail being sent with https://api.drupal.org/api/drupal/core%21core.api.php/function/hook_mail...

For anyone needing to do this, like I also did. Here is an example of the hook @joachim mentioned. I personally believe the module should provide options around whether these emails should be sent or not, but in the meantime, something like this should work:

/**
 * Implements hook_mail_alter().
 *
 * Prevents Commerce License expiry notification emails from being sent.
 */
function mymodule_mail_alter(&$message) {
  // Intercept the license expiry notification email.
  if ($message['module'] === 'commerce_license' && $message['key'] === 'license_expire') {
    // Prevent the email from being sent.
    $message['send'] = FALSE;
    // Optionally log it.
    // \Drupal::logger('mymodule')->notice('Suppressed license expiry email.');
  }
}
