How to write professional emails:

Email is increasingly the preferred method of contact for many professional settings. It is crucial that when you email someone in a professional context (including emailing magistri at TBLS) you should follow some simple email etiquette rules to convey a sense of professionalism. It's far too easy for a sloppily written email to reflect poorly on you.

Professional emails...

1) ...are not the same as Facebook. Use proper spelling, grammar, capital letters, punctuation, etc. Do not use chat language (i.e., "lol"). For the most part, write in the style of a final paper you would hand in for English class.

2) ...have an appropriate (short, to the point) subject line, have a greeting ("Dear Mr. Lao,"), have a succinct and nonoffensive body (where you explain your request, question, comment, etc.) and have a closing ("Sincerely, Student").

3) ...use a sensible font and color (black), in an appropriate size (like this size now).

4) ...shortly introduce yourself, as it is not always clear from whom the email is originating just from the address, especially if it is your first time emailing this person.

5) ...come from a professional email address. "firstname.lastname@whereever" or slight variations thereof are standard and professional (for example, firstinitial.lastname@brooklynlatin.org). For professional use (like emailing teachers, or professors, or colleges, or employers, etc.) it is unfavorable for you to have an email address like "rappaboi14" or "cutiepie12".
