• Initially I wrote a positive review, the plugin worked, apparently there were no problems. But soon I noticed a strange behavior of WP: every time I tried to debug with VS Code, if I stopped on a breakpoint, after a few seconds the loop restarted messing everything up. Eventually, with some trouble and considerable waste of time, I discovered that the “virus” was a cron event installed by this plugin and not removable (action_scheduler_run_queue), executed EVERY MINUTE, probably related to the ‘Smart Routing’ feature, set by default to ON and not modifiable in the free version. In short, the event can only be removed by deactivating the plugin. Definitely not recommended.

    Hi @paolo55555,


    Thanks for writing back and for sharing your experience with the plugin.

    I’d like to confirm that WP Mail SMTP uses the Action Scheduler to manage and schedule cron jobs, and we have this outlined on how WP Mail SMTP executes scheduled events.

    However, the cron jobs are not added by default; they only get added when an action that requires scheduled execution is enabled. In case it helps to mention, the Smart Routing feature is not available in the Lite version.

    From your description, it’s possible that you may have enabled the optimized email-sending option, which sends emails through the Action Scheduler, and this could explain the every-minute cron job.

    To change this behavior, you’d need to disable the option, setting the emails to be sent as soon as they are fired.

    I hope this helps, and please do let us know if the issue persists. Please know that you can submit a forum support thread, including a screenshot of how the cron job appears on your end, and we’ll be able to take a look and advise further.

    Kind regards.
