What should you always do before sending an email to ensure accuracy?

Proofreading for complete sentences and proper grammar is an essential step before sending an email because it helps ensure clarity and professionalism in your communication. Proper grammar and sentence structure contribute to the overall readability of the message, making it easier for recipients to understand your intent. Mistakes in grammar or unclear sentences can lead to misunderstandings, diminish the credibility of the sender, and reflect a lack of attention to detail.

While having recipients in the 'To' field, using a formal closing signature, and attaching necessary documents are also important factors in email etiquette, they do not address the clarity and professionalism of the written content itself. Ensuring well-constructed sentences and correct grammar is foundational to effective communication.
