Hey @Debra,
Thanks for reaching out. The email you mention is indeed one generated by WooCommerce, and so for information about editing it and all of that, you will have to turn to the WooCommerce website and support team.
For example, this guide on the WooCommerce support site shows how to make custom templates for things like the email ? https://docs.woothemes.com/document/template-structure/
Check out that guide and explore other documentation there for assistance.
Let me know if there’s anything else I can try to help with in the meantime!
George
