WP Mail SMTP has the Action Scheduler library, which adds really valuable flexibility for current and future development. Unfortunately, we’ve seen that some sites run into unexpected issues with setting up the datatables needed to let Action Scheduler work. * Using everything we know about these issues so far, and how to resolve them, we’ve published a step-by-step doc [here](https://wpmailsmtp.com/docs/how-to-troubleshoot-action-scheduler-issues-wp-mail-smtp-2-1-1/). * I hope this helps!
