Exactly ! I've done that for years (and for the email alias part, well, at least the last 15 years), and it's a relief. Back at the beginning of the 2000's, I use to get hundreds of spams. So I decided to use an alias of a special mail on my own domain name for each new site I register to. I used alias for not having to configure a new account on my mail client. And then it's super easy to shame whoever sold your email. Best anecdote I have ? An antivirus / antispam brand. I registered as reseller with an alias. Less than a week later, I started receiving unsolicited mail on the alias. I asked them why it happened, but never received anything more convincing than "Mmmm, don't know, let me check". Of course I explained them I won't be buying their product anymore for my clients, and destroyed the alias.
