What does not contribute to effective email communication?

Using complex jargon does not contribute to effective email communication because it can create confusion and misunderstandings among recipients. Effective communication relies on clarity and comprehension; when complex jargon is used, it may alienate or frustrate readers who are not familiar with specific terminologies.

Clear and concise language, including sufficient context, and avoiding acronyms without prior definition are all practices that enhance understanding and make the communication more accessible. By ensuring that the message is straightforward and easily grasped, the sender improves the likelihood that the information will be received and understood as intended. In contrast, the use of complex jargon can obscure the message, making it less effective.
