Pete the plasterer isn't setting up his own domain, you absolute goober. There's a lot of small businesses that are just companyname@gmail.com

Bro over here using megacock420@gmail.com for job applications.

Not everyone has the knowledge/interest/money to buy a domain and set it up with their email, let alone switch their logins to a new email.

When we get resumes, applicants that don’t have some variation of firstname.lastname@… as their email tend to go on the bottom of the pile.

I fully agree with you.
