I have to say that Mailgun is a powerful plugin to make wordpress email work because I receive the TEST email from mailgun successfully. But, I can't get any email notification through mailgun while the woocommerce get any order.

In GCP(google cloud platform), mailgun doesn't work for woocommerce. Finally, the woocommerce new order email notification works by using G-Suite API. The following steps show how i solve this problem. (More information)


Step 1. [Wordpress] Install WP Mail SMTP by WPForms

Step 2. [G Suite] Create a Web Application

Step 3. [G Suite] Grant Permissions and Send Test Email
