Hi,

I read the thread to customize the e-mails sent to the customer after buying but I don't have the menuentry "E-Mails" in System. I use the Essential Edition.

Hi,

The email edition is in the Business version of HikaShop.
www.hikashop.com/extensions.html

Regards,

I don't talk about an E-Mail Edition. I just want to edit (styling) the E-Mail template which will be sent to the Customer after the checkout. Namely Order Notification and Payment notification. Which file(s) I have to edit and will they be overwritten by an update?

EDIT
Ok, found it by myself in media/hikashop/mail.
