Hi,
I don't see the interest, the order notification emails are too different to be handle in an Acymailing email.
The product listing, the addresses, and all other fields won't be accessible so, it won't work.
The templating system in the HikaMarket email is the right solution to handle that.

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