Small businesses often have inappropriate email addresses like firstname.lastname@example.org or email@example.com. This is not at all professional and often makes your company look as if it is not legit.
It really does not take too much time or money to set up a professional email with your own domain name. All you need is a good, low cost hosting company. Look for companies that offer shared web site hosting as this will lower the cost per month for their services. A great option is Concentric.com they offer email services for less than $7 per month or set up a nice web page to go with that new professional email address for less than $10 per month.
With a little more information about your company and a professional email address you’ll have customers that are more confident in your abilities as an actual business. A business should never have an AOL, Yahoo, Gmail or Hotmail email account when professional email and web hosting are so affordable these days.
