Safe mail has been known to cooperate with LE and does not require a warrant, from what I've heard. I recommend tor and a darknet email. A free one I have used is called mail2tor.com and people can write you with or without using tor. The operators don't even know your IP since its on the tor network. You can likewise send to anyone. The best thing is its free.
