Tone: direct, but not curt
Dutch customer service writing tends to be short and to the point, and many brands address customers with je. Flemish customers often expect a slightly more formal tone and u. Decide the default per market, write two or three model replies for each, and keep them in the style guide.
Belgium is a bilingual market
- Flanders writes Dutch, Wallonia writes French, and Brussels is officially bilingual.
- National Belgian accounts usually need Dutch and French in the same queue, and sometimes German.
- Flemish vocabulary differs from Netherlands Dutch in places, so the word list should cover both.
