Do you want to have more people attending your open house events, get more visitors to your online listings and sell more properties? Email marketing has proven and will continue to be an extremely effective medium for the real estate professional. Email marketing is simply the use of electronic mail to connect with (and hopefully, sell to) consumers. It is the electronic version of direct mail. It is targeted to a select number of consumers who are (or would probably be) interested in the specific products or services offered by your business.
