Hi there,
> I’ve checked it and they are not sent out, so it’s probably a problem from woocommerce.
Sorry for the delay and thank you for confirming!
You’ve mentioned earlier that the emails are not sent out when the order total is not 0 and the payment is made via PayPal.
Are you using the default PayPal Standard payment method or an additional PayPal plugin? If it is a plugin – please send us a link to that.
Does the order status change to “processing” or “completed” after the payment is made in these cases, or does it stay “pending payment” and then changes to “cancelled”?
If it’s the latter – there might be issues with IPN notifications:

If the order status changes to “completed” – you may also want to do a plugin/theme conflict test:

Please also copy your System Status Report from WooCommerce >> Status and paste it here.
Thank you!
