When e-mailing on a pager or cellphone, long words are a no-no. Slang like LOL (laughing out loud) or BRB (be right back) saves on text-messaging scrolling and character costs. The shorthand is popular and easy to use, but e-mail aficionados beware. Keep the short stuff out of business e-mail. “If you use slang acronyms, you’d better hope that I get it,” says business etiquette consultant Joli Andre. “I don’t have time to send back an e-mail asking what you mean.” Andre, who runs Polished Professionals (www.polishedprofessionals.com
) in Rancho Santa Fe, California, says the shorthand is just another example of people behaving much too casually in business situations. She also warns against all-lowercase letters, misspelled words, and the all-too-common grammatical mistakes. “Business is serious,” Andre says. “This is other people’s money. As a client, I would wonder, if you are that casual with your e-mail style, are you that way with my business?” So BTW (by the way), save the slang for your BF or GF (boyfriend or girlfriend).
