Why care about etiquette in business e-mails? Y cnt u jst cul8r, ttfn, and lol?
Taking time to use correct grammar, punctuation, and spelling is good business. It shows respect for the reader, reflects well on your professionalism, and, most importantly, contributes to understanding. Everything you write for your business must be clear, concise, and correct.
Grammar and punctuation mistakes and text messaging abbreviations open the door to misinterpretation -- and readers will always interpret something to their advantage, not yours. Believe it or not, some people think LOL means little old lady!
What about those oh-so-cute smilies and emoticons? What's wrong with ;-)? Nothing for friends and personal e-mails, but they are off limits for business e-mails that need to reflect your brand and professionalism.
