3. Uninstalling and Deleting WP Mail SMTP Lite

When you successfully upgrade to the paid version of the WP Mail SMTP plugin, you can go ahead and delete the Lite version of the plugin, as it is no longer needed.

However, before you fully delete the Lite version of the plugin it’s important to ensure your data, such as your settings and saved keys, remain available on your site. This will help prevent you from having to reconfigure your settings when you upgrade to Pro.

To do this, you’ll need to access the miscellaneous settings in WP Mail SMTP by going to WP Mail SMTP » Settings. Then click on the Misc tab at the top of the page.


Next, make sure the box next to Uninstall WP Mail SMTP is left unchecked.


After that, you can delete the Lite version of WP Mail SMTP without worrying about losing any of our data or previously configured settings.

That’s it! You’ve now successfully installed WP Mail SMTP on your WordPress site.
