Yandex.
store all your shit in Russia, where the FSB will tell the FBI to take their FISA bulk surveillance PRISM warrant and shove it up their front hole.
the Yandex. Mail UI is great. no BS, no ads, their phone app is great, plus you can host your own domains on Yandex by delegating your DNS to them.
you should also be using Yandex DNS because Jewgle and Cloudflare and your ISP are all spying on you.
