add email address on customer email

Hi,
(Hika Starter version)

At the Order > Sales > customer record list > go into any order record >
click E-Mail icon > display an email table

Question:
Can I add an extra email address to receive the email? How?
(Because I've try to add an email address after the customer email address by ";This email address is being protected from spambots. You need JavaScript enabled to view it."
but cannot receive any email.

Thanks!
Jade
