6) Best and Most Secure Email for One-up Mission Workers

Suppose you’re a one-up mission worker or mobilizer (that is, you’re not a part of an organization that has a standard email client). What’s the best and most secure email app you can use? We’re assuming everyone will point to Proton ( https://proton.me/mail ), but we would welcome hearing of a better option. For its part, Proton is free, offers 1 gig of encrypted email storage, can’t/won’t open the email account of its subscribers (paid or free), and is lightweight and fast. Paid accounts add more features and space – and they’re not overpriced. Got something that beats Proton?
