Reconfirm user email (and delete account if not)

One of the perks of the GDPR is that we must confirm with ALL users that they agree with us keeping their email. If they are not responding, it means that they don’t want their account anymore, so we delete/anonymize the user.

My question is this: there is a built in way of doing this? Or should I just code a custom solution?
