In the context of addressing an unknown individual in an email/letter, how does one include persons belonging to the broad gender spectrum? For instance, in binary terms Dear Mam/Sir was the norm for a while. What would be the appropriate/ widely accepted way to address an audience which could be non-binary, to ensure that any receiver is not offended?
As a specific scenario, assume that I am writing to a non-academic committee, therefore, the usage of First Name is ruled out ( being too personal), also I cannot use words such as Dear Professor (since the occupation is not Professor). Note that I am aware of previous (old) questions on gender neutral words in a letter and this. Do we have any new words in current usage? While I agree that "To whomsoever it may concern" may be used, as mentioned in one of the questions:
addressing the person by his/her title is a little more specific and evidence that you've put some thought into it.
