You wouldn’t start off an e-mail with “My Dear X”, or “Dearest X”, since that would be too personal for a professional email, so “To X” being more impersonal seems like it would make the letter more professional-sounding, compared to “Dear X”.

      It’s fine for writing the President or your grandmother, but I’d avoid it for anything business-related.

        Or at least, for introductions.

        Probably fine once dialogue is established.
