After you’ve purchased a license and downloaded the WP Sent Mail plugin, install it on your website. WP Admin > Plugins > Add New > Upload Plugin – Select the plugin’s .zip file and install it. Once the plugin is installed you can activate it.
Once WP Sent Mail is activated you should see a new menu item in the admin sidebar WP Sent Mail. The first thing you’ll want to do is go ahead and add your license key at WP Admin > WP Sent Mail > License and once it has been added still in the License settings page, click “Activate Site” – this will ensure that you receive plugin updates as we release them.
