Hi tetro,
Thanks for reaching to us and take our apologies for the long delay in answering.
1. Using a plugin like WP Mail SMTP to handle email delivery.
2. It maybe email-related restrictions or issues on the server that could be causing the problem. They might be able to provide insights or assistance.
3. Please check this manual: https://wpmailsmtp.com/contact-form-7-not-sending-emails/
4. Navigate to WooCommerce > Settings > Emails and make sure that the “New Order” email notification is enabled.
If the issue persists after following these steps, it might be beneficial to seek assistance from WooCommerce support to help diagnose and resolve the problem more effectively.
Best Regards,
