Question

How do I write a "professional" email to my teacher without using dear?
I always write "Dear Mrs. so and so" But I don't think that will work with the teacher I'm writing so does anyone know any alternatives?

Answer 1

Example:

[Input Subject]
Hello Ms./Mr./Mrs. [Teacher name],

[Introduce yourself with your **full name** (Usually first and last) if it's the first time emailing this teacher or required]
[input message]

Sincerely/Thank you, [Your name, class period]
[Signature if optional in the emailing service or mandatory]

Answer 2

Also, I strictly advise you to avoid using slang. Instead, maintain a respectful and firm tone.
