One of the most common (and costly) goofs we see is an incorrect email address.
Since most job search efforts are centered around email communications, having an email address that is wrong or difficult to interpret can be a major pothole in the road to success. Double-check your email address to make sure it is correct. Don't use your work email address on your resume, and try to avoid having an email that has the number 1 in it as it can be difficult to tell if it's a letter or a numeral. Avoid goofy or cutesy email monikers such as "vanhalenlvr83" or similar. Email systems that use automated spam authenticators are loathed by recruiters and line managers alike, so stay away from them during your job search.
Remember, you can set up an email address that you use JUST for job search.
