Spamgourmet lets you do this for free without your own domain, and has other great features also.

Lots of these services get their domains blocklisted eventually, sadly.

Companies tried to block Apple’s Hide My Email in the months after its release, but I haven’t been blocked in years now. I’m assuming they quickly realised that it was here the stay.

Fun fact: Apple blocks using Hide My Email with itself, which I found out once I tried to use it in my contact details when ordering a phone. Their online system reported unknown error when placing the order until I specified a Gmail address instead.

I found two providers in 20 years that blocked my xoxy.net spam gourmet address. It's not that big of a problem.

Been using spam gourmet for 20 years. Basically a flawless service.
