Under Personal settings > Project and work items > Email format, the question in English is: "How do you like your emails?"

In Dutch this is incorrectly translated to "Wat vind je van je e-mails?", meaning "What do you think of your emails?" which is obviously not the intended question.

The correct translation of "How do you like your emails" is: "Hoe ontvang je graag je e-mails?"
