We prefer not to recommend specific VPNs, but a good rule of thumb would be to use a VPN that is based outside of the US and generally paid versions are much more secure than unpaid versions.

A good place to start might be: proton vpn
https://protonvpn.com/
This is a free vpn but is based in Switzerland and TOR compatible.

protonmail is a very trusted end-to-end encrypted email service.
