How can one trust someone with their email account. I believe that is just a weird thing to do no matter whether it was not such a threat before. But your email is something personal.
If you want to use a vpn that is fast enough, you can give a try to PureVPN. It works quite fast as compared to the Express VPN and it is not that expensive too. Moreover, there is also a 7 day money back guarantee if you do not like the service.
So, i guess there is no harm in giving it a try.
