Your email is not nearly as private or secure as it should be. Witopia fixes it with SecureMyEmail. This app provides end-to-end encryption (and other modern security features such as self-destructing messages) for ANY IMAP-enabled email addresses, including major providers such as Gmail, G Suite, Yahoo, and Microsoft. You can send and receive encrypted emails and files to and from anyone with a valid email address. They don’t have to be a SecureMyEmail customer. With your privacy and security in mind, SecureMyEmail uses true end-to-end asymmetrical encryption; this means that your email is encrypted before it leaves your device. No one, not even your email provider, ISP, hacker, or Witopia, can ever access your emails or attachments.
