Which is an essential guideline for sending an email?

Using polite language and phrases such as "please" and "thank you" is crucial when sending an email, especially in a professional setting. This approach fosters a respectful tone and helps establish a positive rapport with the recipient. Politeness in communication can lead to greater willingness to collaborate and respond favorably to requests, enhancing relationships and promoting effective communication.

Being courteous also reflects professionalism and consideration, which is vital in any workplace, including a dental office where communication may involve both patients and colleagues. Using polite language can mitigate misunderstandings and build trust, ensuring that the message is received well and prompts a thoughtful response.
