Your Plugin Templates are not sending in the Email, and we still receive WooComm

Your Plugin Templates are not sending in the Email, and we still receive WooCommerce default template.

I am working on this https://idraulicoperte.it/, and I’m a WordPress developer, Before your email, we were using the YeeMail plugin that was working for us, but there were some issues with that as well. so we buy your plugin but now its not sending the emails and also setup the WP Mail plugin.

Please let me know if you need to access our site, we are happy to provide the details.

Thanks
