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.
