Update orders notify customer email doesn't arrive

[hara]

Hello,

I'm in v1.3.9h. I do Orders edit and Update (Notify customer selected email) on admin site. But the email seems like doesn't send out, because customers never receive the notification emails. How can I check and fit it?

Thanks a advance!

Mike

First step would be to check your email settings in Admin > Configuration > E-Mail Options

If that's all ok then create an account as customer, place a dud order, update the order and check your email box.

When you have done that please give us an update on your findings.
