Here is a tip for anyone who may read this. When you send an email, it should always have a subject. Always. It’s just common net etiquette. An email without a subject is like a book without a title and a book without a title is not something you would want to read because it apparently has no point. If you’re writing an email and you can’t come up with a subject, then you need to rethink whether or not your email has any purpose in the first place and if not, then don’t send the email.
Subjects provide the potential reader with a starting point of what your message is probably about. It sets the tone, makes it so the message is easy to find again later and sets it apart from all of the others. A subject allows the reader to sort messages, follow a conversation, group related messages and most importantly it tells the reader that your message has some sort of purpose.
So please, the next time you’re about to click that send button, take a moment to check your subject field. If it’s empty, fill it in. If it’s not then kudos to you my friend.
