Ask friends and family for references. If they don't know of any, call a few local Brokerages (Real Estate offices) and 'interview' a few Realtors to see who you feel comfortable working with. You need to feel comfortable with the Realtor you hire because real estate is a very important investment.
I am not sure where you are finding the email addy you are using. I am sure they are either dead or your email is not going through or they would return the contact attempt. Try calling if you see a number. We sometimes are harder to find but most all of us carry cell phones, smart phones and are eager to return your call. Try the Find A Pro feature here to find a Realtor in your area, it doesn't have to be the one listed next to the homes you see.
