I do exactly this with a cheap entry tier Google Workspace account tied with a domain for email
I forget the exact setting name in the console for this, but it's a built in feature and works exactly as you'd expect, I can make up whatever I want on the spot before the @ and it'll deliver to my designated inbox
I'd imagine a similar feature would be available at any business-type email provider
There have been a few places that catch it and "error" the email if I try to use the services name in the email, but it mostly makes it through everything I've used it for
