Which communication method is NOT suitable for business purposes according to Netiquette?

The use of emojis in professional communication is often viewed as informal and can lead to misunderstandings. In a business context, clarity and professionalism are paramount, and the use of emojis may detract from the seriousness of the message or lead to varying interpretations based on personal perspectives. While some workplaces may adopt a more casual approach and integrate emojis into their communication style, it generally does not align with traditional business etiquette, particularly in formal or serious contexts.

In contrast, methods such as email communication, formal reports, and video conferencing are recognized as appropriate and effective channels for professional interaction. These methods allow for clear conveyance of ideas, facilitate detailed discussions, and maintain a level of professionalism that is expected in business environments.
