"secure protocol" isn't a really definition of anything. What did you mean to say?

  emails are readable by any of the servers in between the sender and the receiver (which generally neither the sender or the receiver has much control over), and if any of those servers don't support encryption of the link between the servers, so can anyone who can read the network traffic between those servers. Emails also cannot generally be verified, and they can usually be tampered with. Really, any security property you might want is absent from email.

  In terms of communication protocols, "secure" typically it means unauthorized third-parties can't read or modify communication data. Some examples include Hypertext Transfer Protocol Secure (HTTPS), Transport Layer Security (TLS), and Secure Sockets Layer (SSL).
