HeraldNet -- Job hunters often ask why I advise them to send their cover letters (and resumes) through the mail. It’s old fashioned, they tell me. E-mail is faster. Cheaper. Plus, most employers expect to receive job-search materials via e-mail these days. I don’t disagree. Even so, my reason is this: When I worked in a recruiter’s office, we opened every envelope and read every letter. Do you know what happened to the hundreds of e-mails that arrived every week? I hate to say it. They were screened. Sifted. A few messages were reviewed and considered carefully; the rest were set aside or deleted right off the bat.
