...why are you still using a free email account for your business? Hello, business people! It's the 21st century - domains are cheap, so much so that it's ludicrous to not have a domain for your business. Oh, you say you do have a domain for your business? And yet you're not using an email address like firstname.lastname@example.org. Seriously? I'm sorry, but if I find your site and want to get in touch but see an email like email@example.com, I'm leaving your site. I'm probably not the only one who does so. Just sayin'.
P.S. When you buy a domain, you are also buying the ability to have email accounts attached to that domain. If you are paying separately for email addresses in your domain, you are being ripped off.
