Hi Toonster :waving_hand:
Thanks for your post - you can enter multiple emails for a customer within their settings by going to the customer's page > select 'edit' > enter email address' separated by commas within the Email field. When you then create a statement for the customer (New transaction > Statement) this will autofill with all address', and you can remove any from here that you're not needing to send this to. :thumbs_up:
