customize confimation e-mails

how I can change in sending e-mails URL address to Text Link
This is how generate now:
We are pleased to confirm the creation of your order No. K9 at performersheaven.com/ on the 06 July 2014 at 03:45
I like to be like:
We are pleased to confirm the creation of your order No. K9 at Performers Heaven on the 06 July 2014 at 03:45
Also order No. can be more like 4 combination like G64a ??

I find a translation key.

ORDER_CREATION_SUCCESS_ON_WEBSITE_AT_DATE="We are pleased to confirm the creation of your order No. %s at %s on the %s at %s"

Hi,
Yes, you'll have to use this kind of translation :

ORDER_CREATION_SUCCESS_ON_WEBSITE_AT_DATE="We are pleased to confirm the creation of your order No. %s at <a href='%s' > Performers Heaven </a>  on the %s at %s"

Thank You.
That's very helpful
what if you want to customize e-mail, means add some extra inside body e-mails?
Is this involve custom fields creation?
Just need basic info for future reference.

Hello,
It will depend of hat information you want to display through your emails, but yes, by creating custom fields it will be possible to display their values through your emails.
