Hello,
We have some email debugging steps here:

I highly recommend the plugin Postman SMTP. I had email issue on my own site until I installed that plugin and went through the email configurations. Also, I could check the logs within Postman SMTP to make sure my emails were being dispatched. https://wordpress.org/plugins/postman-smtp/
