How do you start a professional email without a name?

If you don’t know the person’s name, avoid overly formal phrases like, “To Whom it May Concern” or “Dear Mister/Miss.” Don’t go too casual either. “Hi” is far too unprofessional for a business email. You might be better off beginning the email with a simple, “Hello.”

How do you say I hope you’re doing well?

How to Say ‘I Hope This Finds You Well’ in a Work-Related Email“I hope you’re staying healthy.” “I hope this email finds you well.” “I hope you are having a productive day.” “How’s life in Detroit?” “I hope you’re having a great week!” “I’m reaching out to you because…”

Is I hope all is well grammatically correct?

It’s a good phrase. A very good phrase. It sounds slightly formal, as if you were writing to someone you don’t know very well, but it’s perfectly correct. If you wanted to be a bit less formal, you could say “I hope you and your family are well.” But what you have written in your question is definitely correct.

Do you say all is well or all is good?

The rule of thumb is that good is an adjective and well is an adverb. Good modifies a noun; something can be or seem good. All you need to remember when you are pondering whether good or well is best for your sentence is that good modifies a person, place, or thing, whereas well modifies an action.
