So sending this stuff over unencrypted email would be better? I think not. The UX here sucks, but sending this stuff over normal email is a completely ridiculous idea. Crypto would be an option but that'd require custom client software, and nobody is going to use PGP. (Frankly, I'd be surprised if it was even legal for the NL govt to hand this stuff to third parties by emailing it)
