I was starting to question my assertion that it's important to send in a hard copy of your resumé and cover letter – email and online applications have quickly become the norm – but this tip from resumé professionals, cited in the New York Times, supports my theory.

[I]f you really want to make an impression, make a hard copy of your cover letter and résumé and send it to the hiring manager by regular mail. Attach a handwritten note that says, “Second submission; I’m very interested,” [Katy] Piotrowski, [author of career books and a career counselor,] said. “I’ve had clients double their rate of interviews simply from doing that,” she said.

[Wendy S.] Enelow, [author of “Cover Letter Magic,”] calls this “double-hitting,” and says she has seen it work remarkably well. She said a senior-level client of hers got an interview and was hired because the hard copy of his cover letter and résumé reached the company president, whereas his electronic application was rejected by someone in human resources because it did not meet certain rigid criteria.
