E-mail etiquette suggests that full caps should not be used as it gives the impression that you are shouting. I prefer to look at caps in one of two ways; as adding strong emphasis or being lazy. With that said, does not using all caps apply to the Subject: line?
Of course there are exceptions to every rule, however in general, being caps add emphasis or are used by those who are lazy, if not properly used in the Subject: field you risk either a misunderstanding or a poor impression. Or worse yet, you could be misidentified as a spammer because most spammers don’t understand the nuances of case.
If you want to bring attention to you e-mail, it would probably be better to structure your Subject: field to include both caps and lower case. Here are several examples that show how using the Subject: field properly can set the tone for your communications even before they are opened.
Subject: FOLLOW UP: Previous E-mail Subject Here
Subject: REMINDER: Tomorrow’s Meeting
Now, one could assume you were shouting if:
Subject: WHERE’S MY ANSWER?
Subject: DID YOU GET MY E-MAIL????!!!!!
See, these little “enuances” make the world of difference in how the Subject: is perceived! It’s all in the words you choose and how you choose to use them that can determine if you will be perceived as shouting, being rude or offering the epitome of professional communications.
Perception is a delicate and subjective thing and in business can make or break you. With e-mail, however, you do have within your control to control how you choose to format and structure the words you use to ensure you are perceived favorably and as the credible professional that you are!
