My solution to spam emails is this: https://ahmedkaddoura.com/writing/hide-my-email

I create a unique iCloud Hide My Email anytime I need to give out an email. The issue here was I signed up for my 24 Hour Fitness membership in person at the gym where the cell service was bad and I couldn't get the WiFI to work, so I begrudgingly gave the guy my real email.

While I could have easily blocked their domain, I took it as a challenge to get the emails to stop.

I use Fastmail which allows me to have a catch-all with my own domain name. I don't need to set anything up to give out a unique email address I make up on the spot. I highly recommend this method.

The flipside of this is that it's extremely easy to spam you by just iterating new email addresses.

I do it and never had an issue. I get odd emails every now and then with an unused address, for services/people I never contacted though. But I'm talking about perhaps 2-3 per year.

It’s extremely easy to spam me on any address I give.

They all end up in spam.

I think I got webmaster@ once.

Don’t they have a list unsubscribe header in the emails themselves? That’s effectively a requirement for senders of their size since Feb 2024.

I see this in the headers. But there was no option in the MacOS Mail client to unsubscribe. Only the Unsubscribe link in the body of the email.

> But there was no option in the MacOS Mail client to unsubscribe.

The functionality for mail clients to offer an "unsubscribe" button is dependent on there being a "List-Unsubscribe" header in the e-mail with a URL:

* https://datatracker.ietf.org/doc/html/rfc8058

* https://datatracker.ietf.org/doc/html/rfc2369#section-3.2

If the sender does not put one in then that's hardly the mail client's fault.

MacOS should have list unsub support from what I can see: https://support.apple.com/en-gb/guide/mail/mlhld3405766/mac

Dependent on the e-mail sender putting a header with a URL in the message:

* https://datatracker.ietf.org/doc/html/rfc8058

It’s effectively a requirement since Feb 2024 when Google and Yahoo rolled out guidelines related to it for bulk senders.

Wildcard addresses wins this round.
