Marketpress Email Question!

I have a problem that I can’t seem to figure out on my own. I have a client that does not want to receive new order notifications but does want to receive emails from users who reply to their order confirmation emails. Is there any way to send the order confirmations from my client and not have him receive any new order notification emails?

I’ve tried several different plugins such as Mail From and WP-Mail-SMTP but they don’t seem to work. Right now I am using my email address under settings and having to forward him any buyer emails that come in.

Any help would be very much appreciated. Thanks!
