I'm also doing this and see multiple benefits.

However I've recently been bitten by my catch-all, using a money transfer service with the email [e-mail] (guess the company). When they asked for additional documents to verify my account after many months, they never received my reply and I ended up banned. I could not login anymore. When I reached out from another email address, they refused to process the documents because they originated from another, unauthorized email address, and asked that I resent the original email from the registered email. I suspect their anti-phishing filters just ban any email containing "worldremit", so it never got through and despite multiple thorough explanations I could never get someone to listen or reinstate the account.

I'm still getting the newsletter though, because unsubscribing requires logging in first... But then I can just ban this email address, so at least the anti-spam strategy works!

There's something even worse than the "please write to us from your original email". On a number of occasions, I've had some random people use my email address to sign-up for something and then occasionally I have to actually contact a random company to unsubscribe me and/or delete the account.

When this happens, I've had a few insane companies insist that I send them a screenshot from my gmail app/web page, etc. to "prove" it's my email address. I have steadfastly refused despite some rather angry responses insisting that I have to. I have responded very strongly and politely that I have to do no such thing as I have no business relationship with their company. Usually once I point out that they're sending someone else's private information (receipts, etc.) to a completely unrelated individual and they could be held liable they relent and delete/unsubscribe my email address.

The most insane of these was when Uber started emailing me someone's trip receipts every time they took a trip for someone in Australia. When I contacted them, they refused to believe me and said it wasn't possible. I ended up finding one of their technical VPs on LinkedIn, messaged them blindly, and "mysteriously" it resolved itself two days later with a polite apology.
