According to psychologist Carole Lieberman, using ASAP in an email puts pressure on the receiver to complete tasks "yesterday." "It indicates that you're behind," she explains. "Rather than simply stating "ASAP," give folks a specific deadline." Also, writes communication expert Alissa Dixon on her website Smarter With Style, "Asking someone to get back to you 'ASAP' or saying you'll get right to it without giving them a time frame can be interpreted as impatient and disrespectful." Instead, she says, use words like "immediately," "soon," and "before long." And lastly, notes Dixon, "You should never, ever use the word 'rude'"--so don't do it!
