On your resume, you should have your name, phone number, cell phone number, email address, and if you have one, a link to your business related blog, and linkedIn account.
KCDEE recently had a booth at two area job fairs. We were collecting email addresses from people who were interested in receiving our e-newsletter. As I was entering the names and emails, I noticed that about 95% of the names were professional in appearance. But, alas, there was that 5% that could potentially scare away an employer from contacting you.
The best thing to do is to make your email address recognizable to anyone who may wish to contact you about a job, contract work, or a potential business relationship. If your name is very common adding a number to your name is acceptable. Other options include first.middle.last@ email address or perhaps first_last@ email address, or last-first@ email address. There are many free email services including hotmail, yahoo, gmail, as well as, the phone and internet providers in the area such as comcast, att, and sbcglobal.
Presenting a professional face on all forms of communication with potential employers just gives you more ticks in your win column. Read more about email addresses.
