Hi @zoolo
There’s a number of reasons why emails are not being received when they are sent from your site.
What I would suggest is to check if the emails are actually being sent (and not received), or if they are not being sent to begin with. You can find a quick guide for that, using a plugin called WP Mail Logging, right here:
https://docs.woocommerce.com/document/email-faq/#section-4
If?WP Mail Logging?shows the email being sent, but it’s not received, that means that the issue is not with WordPress/WooCommerce, and it could be with the SMTP provider, or your webhost, or on the receiver’s end. You will need to troubleshoot with your SMTP provider and your host.
If?WP Mail Logging shows the email as not being sent, you will see an error message as well, which could point you in the right direction and give you some information about what might be wrong.
