The above has been added to the internal email but when I create a test order with the product that has the MPN and the email is received, there is nothing there.
thanks, you were right about the formatting. I have now added another custom metafield to my products which is a single line of text and it’s working when added to the email in flow. I just want to confirm, this is only visible via the back end/internal use? I was originally going to use the barcode field but found that using the barcode field for this use would have resulted in ‘fake’ barcodes and would have had a negative impact with google/merchant centre. Thanks again for taking the time to reply.
