Note: key values start with "Variable" (with a leading capital letter).

        list.add(map);

Ok.

        context.put("emailList", list);

Ok.

#foreach ( $email in $emailList)
        Transaction No: $email.variable0
    <br/>

I think you want:

    Transation No: $email.Variable0



I think you just need to capitalize "Variable0" and you'll be good to go.

Velocity first looks for a method called "getVaraiable0()" on whatever object "email" is. Since "email" is a map, that method does not exist. Then, Velocity looks for a method called "get" that takes a String argument (which Map does), and calls get with the String from the reference (in this case, "varaiable0"). Note that the lookup is case-sensitive.
