That information would still be meaningless unless we could prove that this e-mail is authentic. `v.pozharskyi.ukraine@gmail.com` - why would an Ukrainian citizen have "ukraine" in their e-mail address?
There are so many other red flags (in addition whether this e-mail was really send, and the account belongs to that person) for example if Hunter responded to it (if they had his laptop surely they could get that from outbox? Why somebody who cares enough about their laptop to get it to repair (if you have plenty of money, more likely you'll get a new one) not care about getting it back?
This would prove that gmail indeed sent the e-mail, but it wouldn't prove that the e-mail wasn't created few minutes earlier.
