Membership Number in Order Email

Hi,

I’ve searched the forum & Googled but can’t find an easy answer. I run a site where both members & non-members order, so on the order emails that we (the customer) receive I need to be able to tell whether the order is from a member or not. Using Woocommerce Memberships but I can’t see a way to just change or update settings in order to do this?

Any ideas?
