Hello,
Thank you for reaching out to us. We are sorry to hear that you did not receive any email after creating a new account and placing a new order. Please kindly check your spam or junk folder, as sometimes emails may be filtered there.
If you still cannot find the confirmation email, сould you please test if the same issue occurs when using a default theme, such as Storefront? (Appearance > Themes).
If the behavior continues regardless of the theme being used, it suggests that the problem may not be related to the theme itself. In this case, we would recommend you contact support of woocommerce plugin – https://wordpress.org/support/plugin/woocommerce/
Best Regards,
8Theme’s Team
