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”.

At every single company I’ve worked for this has been the accepted form of opening an email. There are hardly any circumstances you should be using “Dear (insert name here),” in a work email.
