I use iCloud’s Hide my Email feature. So I have dozen email addresses and I receive email in the same inbox. I don’t care how my email addresses are used. The moment I see too much spam, I remove the email address.
I love this feature in Apple’s ecosystem so much. The newer iOS and iPadOS releases when autofilling a sign-up form even give an option to generate a new hide my email address. It’s effortless to not use your real email. If you pay for an iCloud subscription, hide my email is included. Apple tracks what site you used hide my email on when signing up and allows you to toggle forwarding of emails to your inbox on and off.
