Activate your voice
Writing in the active voice gives your writing life by having the subject do something related to the verb. A more active style of writing reads as more assured and self-assured, and it can help you cut down on wordiness.
Be mindful of context
Does the individual you’re speaking with possess the same knowledge and worldview as you? If not, be certain to include context. You only need to fill in the blanks so that your message is understood; you don’t need to provide the complete narrative.
Correctly format your email
Make sure your email is formatted properly. Create a compelling subject line for your email so that the receiver feels driven to open it. Be familiar with appropriate email salutations and closings.
