open letter
Published personal address
An open letter is a letter addressed to a specific person or group but made public, usually through media or publication.
The format combines personal address with public appeal—the nominal recipient may matter less than the broader audience.
Open letters often criticize, petition, or call for action: Fifty scientists signed an open letter warning about AI risks.
The form lends weight to complaints or demands that might otherwise be ignored.
