So here we are, on the eve of the new (European) legislation coming into force, and very confusing it has been! No standard format: as many different versions as there are organisations it seems. The essence of the law seems to be CONSENT, but many organisations are getting round that by, instead of asking for consent for info to be held, and emails to be sent, just using "implied consent" - i.e. "do nothing and you can stay on our list". And there are a couple of companies who email me almost daily, who have said nothing at all about GDPR or "reviewing our privacy settings".
For those who require an "opt in" I have simply not replies so that I will effectively be unsubscribed.
The ones that really annoy me are those who either have no unsubscribe button or who ask you to "log into your account" (non-existent)"if you wish to unsubscribe".
What a mess!
