Since you are declaring the Email variable inside a function(in local scope), that's why it is not accessible outside of this function. Instead, define it outside like this as a global var :

var email;
function promptMessage() {
    email = prompt("Enter your Email :", "");
}
function Email(){
    alert("Email Address is " +email); //Email from promptMessage() function 
}

How about

function promptMessage() {
    return prompt("Enter your Email :", "");
}
function Email(email){
    alert("Email Address is " +email); //Email from promptMessage() function 
}
Email(promptMessage());

Just declare it outside of the scope of the functions and dont use a function name as a variable name this will leed to nightmares:

var EmailAddr;

function promptMessage() {
     EmailAddr = prompt("Enter your Email :", "");
}
function Email(){
    alert("Email Address is " +EmailAddr); //Email from promptMessage() function 
}
