I have sent an ebay order number to a seller using my private email, by copying and pasteing it from my account; I forgot to remove the underscore that make the number a hyperlink. Form my sent folder, when I click the order number of the sent email, I do enter my account. Does it mean that the receiver can also now enter my account?
I have no idea what you mean. Why have you sent an ebay order number to a manufacturer?
What does a manufacturer need an ebay order number for, I doubt whether it means anything to anyone but ebay.
