That's actually not uncommon for a lot of wrestlers to promote themselves with personal email accounts, especially those in AEW that are allowed to take independent bookings on the side.
Lolz is Mercedes using a gmail account?

I mean it's common for a LOT of
entertainers to use personal/professional email accounts for bookings.
Are you expecting WRESTLERS to know using gmail instead of buying a domain, using that domain for your email? A reoccurring cost that THEY have to maintain and what happens when you forget to reup your domain? I mean you're on the road 300 days of the year doesn't seem impossible that a person whose trade isn't in tech might miss that. Someone else swoops in and buys your domain so now you no longer have your domain and have to buy it back from a stranger. So it just seems easier to use gmail.
But maybe that is a job opp for someone just setting up cloud services for entertainers like websites, email services, etc...
