ユーザーのメールを再確認(確認されない場合はアカウントを削除)

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?

アカウントを未アクティブ化に設定し、アクティブ化メールの再送を強制することで、この処理を完了できるはずです。
