Remember when all formal correspondence started with To Whom It May Concern? These days, if you receive an email with that as the opener, you’re more likely to send it straight to the trash. The days of proper letters have come to an end, but that doesn’t mean you should use loose, casual language and expect to get what you want. A formal email is not the same as an effective email, but combining the power of the two gives you a better chance of getting the reply you desire.
