Standard formatting still applies. Some people like to save their resumes as a text document within their e-mail. This sometimes creates bad formatting and encoding errors. Most employers do not mind if you simply copy your resume into the body of your e-mail. We realize that the formatting won't always keep its integrity and when we want a perfect resume we will get it from you personally at the time of the interview.
Paper Use a good quality paper, preferably bonded.
Off-whites are often recommended because they stand out from the majority white. This still holds true because a lot of faxed resumes will reside on any recruiter's desk and your nice, thick off-white paper will stand out. However, to overestimate the value of a good paper is foolish. Make sure the paper is decent quality but don't break the bank getting paper that could double as card because it's so thick. A word of warning about paper.
