Just to be sure, a couple of things to check first:
1. Could you please make sure it’s not going to your SPAM folder. 2. What about other WooCommerce emails (e.g. “new order” email)? Are those working normally?
If that doesn’t help, maybe it’s possible for me to log in to your site to check what’s going on (my email is [email protected]). Please let me know if sharing an account is not an option, and I will continue solving it remotely.
