How do you say good evening in email?

Such email format suggests using the following phrases: “good morning,” “good day,” “good afternoon” or “good evening.” As you do not know who you’re writing, choosing a neutral phrase is preferable to avoid unnecessary irritation. The idea of checking mistakes in the text before sending a formal email is a great one.

Is Good afternoon capitalized?

Typically, “good morning” is capitalized only when it’s used as a salutation at the beginning of a letter or email. The same rule applies to “good afternoon.” Don’t capitalize it unless it’s a salutation in a letter or email.

Good evening can be used to say hello once it gets dark outside and the time varies depending on the season. Good evening can be used to say goodbye usually just after it turns dark outside. Good night is usually used to say goodbye later on at night when people separate for the rest of the evening/night.
