I used to just add the +something in my email but now I try and remain diligent to create a masked email. When I first started, I foolishly did it with my domain name but have since moved to creating it with @fastmail.com.
I did it like the first one first then moved to the second, where @smthg.com is my domain, but it also has my name in it so it seemed counterintuitive to link my name to it.
