And Your Point Would Be...?
When possible, be brief. Get to your point as quickly as you can. However, please don't leave out necessary details. If providing a lot of background information will help the recipient answer your query, by all means, include it. You may even want to apologize for being so wordy at the beginning of the message.Plz Don't Abbrvt.
My teenage nieces send me email using all sorts of abbreviations -- U instead of you, 2 instead of to or too, plz instead of please, and thanx instead of thanks. It's fine for personal email. Business email should be more formal. Of course, frequently used abbreviations such as Mr. and Mrs., FYI (for your information), inc., and etc. are fine.What's In a Name?
Take a look at your email address. What does it say about you? Are you a sexymom@isp.com? Maybe. But do you want a prospective employer to think so? Think of getting a more formal address. Perhaps your first initial and last name would be good. If you're really attached to your address and don't want to change it, consider adding a second one for professional use only. If your ISP (Internet Service Provider) only provides a single address, look into getting a free account. If you're currently working, you may have a company email account. Do not use this address for job hunting purposes. Use a personal account only.
