Secure and open source. Secure. Security is priority in my book and for now this App meets the requirements. Other high rated Apps like Aqua mail have analytics in their App. Blue Mail another high rated App has loop hole where your mail passes and can be held on their mail server. K9 mail is open source which means it can be inspected for security risk. Reviews on Internet show it to be safe and secure across the board. Not the best of interfaces but worthy trade off for me. It's free and secure. Well done K9.Thx
