Safe-Mail is hosted in Israel, which has a liberal intelligence sharing agreement with the US, which is part of the Five Eyes along with Australia. So they all share a lot of intel with each other. I'd stay away from Safe-Mail, because even if you PGP encrypt every message, your metadata is not safe. Find a clearnet provider in Russia, South America or Asia. The less friendly the country is with the Five Eyes countries, the better. The web site doesn't have to be in English. Pop the text into a translation service to figure out what you're doing long enough to get a desktop email client set up. Configure Thunderbird + Enigmail + Torbirdy to work with the email provider's POP/SMTP settings. And obviously PGP encrypt all messages. Enignmail integrates PGP into Thunderbird, Torbirdy configures it to route traffic over Tor and adds other anonymity features like changing your time zone to GMT and scrubbing email headers. This is the best way to use clearnet email, imo. It avoids the need to visit a web site and turn on Javascript.
