I've actually had decent experiences in the last few years. The vast majority of services have a clear opt-out link, and pretty much everything else has an unsubscribe link in the emails that works. I think legit senders are terrified of getting spam blacklisted, so they have to offer than option.

The only exception I found was the democratic party mailing list. No idea how I even ended up on that as I don't live in the US, but NEVER give them your real/main email address. The spam is relentless and impossible to block because they are continually setting up new domain names.

Some "legit" senders only have a "snipe"-unsubscribe: you can only unsubscribe from a given "list", which often has just one message.

When a new ad campaign occurs, they create a new "list" and mail everyone again.

This is spam.
