 * Hey [@jogurtt](https://wordpress.org/support/users/jogurtt/) ,
 * That error will happen when you click the Send Test button from the settings 
   page. It intentionally triggers a fatal error so that you can make sure the email
   notifications are working.
 * If the error happens when you activate the plugin, it could be something at your
   host preemptively checking to see if the plugin *could* cause an error. Since
   the test is designed to trigger an error, I’m not sure how we can get around 
   that, but maybe we can come up with something. Who are you using for web hosting?
 * Thanks
    Jack

 * Hey [@verygoodplugins](https://wordpress.org/support/users/verygoodplugins/) 
   
   Thanks for the reply! You’re right- the error was triggered when I manually tried
   to send an email notification. I mistakenly assumed that since the email didn’t
   arrive, the error was the cause. I’ll keep digging. Appreciate the quick response!

 * Glad to hear it 🙂
 * If you’re using a third-party SMTP service, it’s possible it hasn’t fully loaded
   or initialized by the time the error is triggered. Our next update will fall 
   back to the server’s `mail()` function in cases where a plugin (like FluentSMTP)
   isn’t available.
 * If you are using a service like that you could check the logs to see if it *tried*
   to send. WP Mail Logging is also helpful with this: [https://wordpress.org/plugins/wp-mail-logging/](https://wordpress.org/plugins/wp-mail-logging/)
 * Finally, because the notification emails contain debugging code, they often go
   to spam, so make sure you check there 🙂
