Hi there tracylove! Welcome back to the forums. 🙂
Awesome, I’m glad you were able to track down the email in your junk folder. Preventing that from happening is using something that needs to come from your email server/host. You could send emails via a secure SMTP protocol and that might help as well. Unfortunately, there’s not much that can be done from the plugin’s end on that, but here’s a nice article on the WooCommerce site that helps break down email a little better.
How do I have the system automatically mark the order as “Complete”?
You might want to consider this add-on plugin for WooCommerce. Similarly, there is a snippet that is supposed to do that that can be added to your functions.php file.
Does this help answer your questions? Please let me know. 🙂
Cheers!
Geoff
