Why do you ask for name etc - when I want to get rid of your marketing messages?
Nothing like a data grab on the way the door from the mailing list.
Which I am sure doesn't meet some basic GDPR tests!!!
As an added precaution to ensure you are unsubscribing not someone else.
When I need to fill in a data grab, I use Joshua Ormond’s email address and a random name. That way he cannot unsubscribe. ;-)
Most hosting services (where you host your email) will let you set up "forwarders". Forwarders appear (to the user) to be regular email accounts but only forward emails to another address (hence the term "forwarder"). Thus, when you get sick of someone spamming you, or for any other reason, you just delete the forwarder and the sender never knows the actual destination email address the forwarder was forwarding to.
When any website or other asks me for an email address, they get a forwarder instead. They don't (need to) know the difference.
I have about 200 forwarders set up.
Gmail has a little know feature.
If you have an address like email@example.com (or a google apps account for your business) you can enter a + with extra characters to create a custom address. Like, firstname.lastname@example.org, or email@example.com. That will come to your inbox too. Then you create a Gmail filter to skip your inbox and slap a label on it (or send it to a Spam folder).
If you want to test a company's email trustworthiness, you can use a specific address for a sign up like, david+FMIJuly2018@gmail.com and see if you ever receive emails from non-FM companies to that address.
