What does your email address say about you? Does your email address end in 'yahoo.com', 'aol.com', 'comcast.net' or some other ISP ending? If you are using an email address linked to your internet service provider, then you are saying that you aren't taking your business as seriously as you could. I understand that using an email from your provider is easiest but it's not difficult to get a professional address. If you are using your ISP address then you seriously need to consider purchasing a domain name and email address to go along with it. It doesn't cost much (maybe $9-12/year) and will really help elevate your image from hobby REALTOR to full-time professional REALTOR. My suggestion, use your name (first@firstlast.com). It projects a very intentional image. See if your name is availabe. If you need help setting it up, let me know.
P.S. If you are using your broker's email address (remax.net; coldwellbanker.com; cressyeverett.com) then you may want to consider obtaining your own personal email address JUST IN CASE you ever switch companies. You still will want your clients to find you.
Great advice and it is important for branding yourself!
