 * Does this plug-in queue messages for delivery in case there is a problem with
   the SMTP connection? I am still trying to resolve a random Error 454 with my 
   provider (Hostinger) and I can’t seem to confirm that messages are retried and
   eventually delivered. I suspect they are NOT unless there is a long delay.

 * Hi [@wbenterprises](https://wordpress.org/support/users/wbenterprises/),
 * WP Mail SMTP does not queue the emails for delivery. Our plugin attempts to hand
   them off to the mailer service immediately. Our Pro version, however, does have
   the ability to resend emails. It’s part of the Email Log feature, which is not
   available in the free version of the plugin.
 * In case it helps, check out this guide in our documentation. It walks through
   our email logging feature: [https://wpmailsmtp.com/docs/how-to-set-up-email-logging/](https://wpmailsmtp.com/docs/how-to-set-up-email-logging/)
 * When you have trouble getting email, the first step is to check the debug logs.
   If there is an issue communicating with the mailer service, the debug logs will
   often show an error message that can help point to the problem. Check out this
   guide on our site. It walks through our Debug feature. Using the Debug system
   in WP Mail SMTP, you’re able to check the logs of failed emails and any available
   error messages: [https://wpmailsmtp.com/docs/how-to-debug-email-sending-issues-in-wp-mail-smtp/](https://wpmailsmtp.com/docs/how-to-debug-email-sending-issues-in-wp-mail-smtp/)
 * The debug log may provide additional details to you that can help you while you’re
   troubleshooting.
 * I hope that helps! Have a great day! 🙂
