Test email takes forever

Hi guys,

I tried using this plugin to solve an email sending issue with woocommerce, but when I test, it takes forever and the status message doesn’t change or refresh page. When I try to make purchase with plugin activated and configured, it simply stays loading forever too in frontend. This also happened with another plugin I tried.

Do you have any idea of why this happens? My site is really new. Doesn’t have much plugins installed.
