Never send your credit card info via email. Many email messages are send using plain text, and are not a secure means of sending.
I'd go with Flamenspiel's advice. If you don't hear back from Hotels.com you could call them with the card info after verifying the phone number. At the end of the day you are protected against credit card fraud; as long as you don't contribute to the fraud.
Also use a secondary card if you are going to do that- not the one you are going to need on your trip.
