It’s not just Protonmail.

Blacklists like these aggressively and unapologetically collect all privacy-focused email domains they find, including simple forwarding and tagging services. With more and more sites using these lists to reject or black-hole email addresses, it has become difficult to protect one’s self from spam and cross-site account tracking.

Dear web developers, please don’t use these lists. Well-intended or not, they are privacy and user-hostile.

It’s a rare treat to see somebody raise a concern while at the same time doing something (PR + discussion). Kudos to you!

I’ve seen other similar lists with the same issues (c7 I think?).

This is going to be a mesh if all private email providers are blocked.

I saw the other day Tuta complaining that Outlook has been sending emails from tutanota.com straight to junk/spam. What’s surprising is tuta.com emails were fine. So not sure if their domain change had anything to do with it, or if MS is doing the same thing as in the OP.

Ugh. I don’t like i this evolution. Simple login is pretty handy to avoid jumping through hoops to unsub from companies.

Recently had a site where I bought something once without having to register spamming me with Christmas mails. If I wanted to unsubscribe from the mailing list I had to register before I could unsub.

Just deleting the simplelogin alias is a lot less work than unsubscribing is most of the time… And my actual email address isn’t leaking either so… Profit.

What is this? Does anybody actually use it?

It is logical that large corporations that base their economy on surveillance advertising hate users who protect their privacy by using all kinds of dirty tricks to bypass or eliminate these protections… Luckily I have had no problems so far with the Proton, Tuta and Murena (NextCloud) emails that I use.in the EU.
