I work in IT, and part of ITs duties is managing the enail filter and investigate emails detected or reported as phish or spam.
We don't normally see the actual email, but we get basically all the metadata, you can see all sender information, super useful when dickheads try to spoof the sender, we see all URLs in the emails, with a wuick summary of if it is a bad URL, attachments as well, they all get scanned and we get warnings about them if shit is bad.
I take great pleasure in blocking senders and reporting spam/phishing to improve the global filters.
If a bad email campaign has gone through the filter we have the tools to find the emails in the differebt mailboxes and delete them, the system is also capable of doing this automatically if it detects bad stuff after delivery.
Meanwhile microsoft's exchange online can't even prevent attackers from spoofing microsoft.com as the sender. I nearly got caught by a fake quarantine notification once. The thing that made me suspicious was that the fake login page only took a second to load. The real one is never that fast.
The entire quarantine BS is trying to reinvent the wheel of the spam folder and causes a shitload of headaches for our internal IT.
IMO that's unacceptable too. State that you've been unsubscribed on the confirmation page and never email again. You literally just told them never to email you again and they immediately emailed you. Also the ones that say "you'll be removed from our mailing list in 2-3 weeks" should be fined. It doesn't take 3 weeks to process an unsubscribe. Sure, it can take a day or two to propagate through all the databases if they use a convoluted database schema, and sync jobs, but WTF is up with 3 weeks? They're just like "we're going to go ahead and keep sending you shit for a few weeks. MK?". Fuck you!
Definitely no to all that crap with weeks delay, unsubscribing should take seconds or at maximum until next DB sync, and that can't be more than a few minutes.
Because the laws requiring them to unsubscribe you give them up to a certain amount of time to actually do so. And corporations employ stalker logic and figure "if I can just talk to her she'll understand that I'm not actually a bad guy!" Instead of just respecting your decision from the get-go.
I think it depends on the sender... Traderjoe.com is probably just going to delist you. [email protected] probably is just going to sell your email address to everyone.
Using SimpleLogin, I create an alias for every new sign up and just turn it off if not needed. Only give your personal email to people not apps and websites.
