Passive voice in email etiquette is often perceived as a way to soften requests or convey formality. It allows the writer to focus on the action or the result rather than the doer of the action. This can be seen as a way to maintain politeness, neutrality, or diplomacy in professional communication as it shifts the emphasis away from assigning blame or responsibility directly.

Passive constructions enable writers to communicate in a more indirect manner, which can be useful in delicate or sensitive situations where directness may come across as rude or confrontational. It helps in maintaining a sense of professionalism and respect by avoiding direct accusations or commands.

However, excessive use of passive voice in emails can reduce clarity and make the communication less direct or authoritative. This can lead to misunderstandings or ambiguity in the message being conveyed. It may also come across as evasive or lacking confidence, especially in situations where clarity and directness are essential.

In conclusion, while passive voice can serve a purpose in email etiquette by adding politeness and diplomacy to communication, it is important to strike a balance and use it judiciously to ensure clarity and effectiveness in conveying the intended message.
