Hi,
You can edit the emails in the HikaShop backend : System > E-mails
www.hikashop.com/support/documentation/i...p-email-listing.html
This feature is only available in Business version of HikaShop.
By editing a email, it will change the template for every one.
You can't have like that one e-mail template per customer. It could be possible but it will require some custom development.

By the way, do not send me private message, use the "contact us" form instead.
