unfortuantely lots of messages are not marketing and in some cases companies have legal duties to send them. My German bank insists on notifying me that I have a message. They can’t send the actual message (for security reasons), and I can’t opt out because they have a duty to inform me. Infuriating but seems to fall within the legal framework :(
I tried but to no avail. My German is very basic which makes things even harder. From what I recall they have a legal duty to notify me, and email is an acceptable form of notification, and that’s about it. I ended up using a unique email address and then let it bounce, but not sure it’s the wisest thing(?). I don’t actually need any emails from my bank, so thought it was an ok solution, but not great.
