I know a guy that has a @linux.com email address. And yes putting that email address on his CV and Linkedin has resulted in him getting emails daily from companies asking if he’d be interested in a position or interview. He’s even had people just straight up offer him a job because of it.

Note though he’s a web developer and pretty much all the jobs offered or interviews etc are for positions out of his skillset i.e. system admin, server manager, IT, data analyst, etc. because they all see the linux part and figure he can run a server or something.
