When you register a domain name you automatically acquire several email accounts that can be personalized for your business such as customer_service@dansmufflers.com, info@dansmufflers.com or sales@dansmufflers.com. The account names can be any thing you want with the "@dansmuffler.com" extension (remember this is an example...your account extension would be @your_choice.com) A good example would be dan@dansmuflers.com for customers that you would like to directly contact you on a personal level.
