E-mail from Gezondverzekerd.nl in your mailbox

Do you use group health insurance? Then you may have received an e-mail from Gezondverzekerd.nl on 25 July. Via Gezondverzekerd, the municipality asks for data for a re-examination. So it is not a spam message. In addition to an e-mail, you will also receive a letter by post. Is your e-mail address not known to the municipality? Then you only get a letter.
