Your sign-off gives you the opportunity to wrap-up the tone and intent of your e-mail. Not including a closing may seem abrupt, bossy, demanding or impersonal if you don’t sign you name with an appropriate closing.

When asking for assistance, always close with a TIA, Thanks!, Appreciate your support! — something that reflects your sincere gratitude for the time that you would like to be spent helping you.

Included with your closing should also be your name. How you choose to sign-off, as well as how you type your name, sets the formality of your e-mail. Whether you use, for example, Charlie or Charles, Susan or Sue — will have an affect on the perceived level of formality in which you are communicating with that particular recipient.

Little things make a big difference when in comes to e-mail. Don’t forget an appropriate closing and sign-off. In business the last thing you want is to be perceived as terse or rude.
