This usually happens when the payment gateway isn’t properly updating the order status after a successful transaction. WooCommerce triggers emails based on order status, so if the status doesn’t change (e.g., stays “pending”), the email won’t send
I’d suggest checking:
- Order status after payment (should be processing or completed)
- Any conflict with the payment gateway plugin
- SMTP/email setup (since WordPress relies on
wp_mail() and hosting can affect delivery)
Also, using an SMTP plugin + email logging can help confirm whether emails are being triggered or failing silently.
