Miscommunication happens all too easily over email! If you're ever in doubt, pick up the phone. Email is a very efficient and convenient form of communication. But because it's so impersonal, your words and intent may be misinterpreted.
First, always strive to be as clear as possible, even when you're in a hurry, and remember to read what you've written before you send it. If you sense that a potential conflict may be brewing, pick up the phone and talk it out. It's worth the minor inconvenience.
Many problems can be avoided this way. Relationships are built through dynamic conversations. So make the effort to pick up the phone, and even better, meet the people you are corresponding with in person.
A mistake is really only a mistake if you continue to make it. You're missing out on an opportunity to be and do better if you don't analyze yours.
