You can write a very simple function like this:

function existsInArray( arr, item ) {

    for( var i = 0; i < arr.length; i++ ) 
        if( arr[ i ] === item ) return true;

    return false; 

}

Or use Underscore.js inbuilt: _.indexOf( arr, item ); function. :)

It will be solve your problem:

if ($scope.Email.indexOf($scope.user.Email) !== -1)
            {
                console.log("Mail Id Already Exists");
            }
            else
            {
                $http({
                    method: 'POST',
                    url: 'index.php/Welcome/Signup',
                    data: $scope.user,
                    headers: {'Content-Type': 'application/x-www-form-urlencode'}
                }).success(function (data) {
                    $scope.Enquiry = data;
                    console.log(data);
                    $location.path('/EnquiryResponse');
                });
            }
