Hi,
Thank you for using CusRev.
Currently, the Q&A feature works based on the WordPress comment system and it has not had an option to send email notifications to the customer who has a question or answer. I’ve informed the development team to consider supporting this feature.
For now, you can follow this article to know how to achieve your goal with a third-party plugin https://www.wpbeginner.com/wp-tutorials/how-to-manage-wordpress-comment-notification-emails/.

Just wanted to share an update that we added an option to send email notifications about replies to Q & A in the version 4.43 of the plugin. If you would like to receive notifications about new questions, please enable the standard WordPress notifications about new comments as we suggested above.
