If you just want to check length > 0 , I would suggest to use the required attribute on your input, and then check your form with angular like

<form name="form" novaldiate>
    <input type="email" ng-model="Email" name="Email" required>
</form>

Then you can check :

Is this is a valid Email ? {{form.Email.$valid}}

(easier if you email come from a form)

You are assigning x to an object. Therefore x.length will always return undefined. You can assign x directly to your scope variable:

$scope.CheckEmail = function () {
    var x = $scope.Email;
    if (x.length >= 0) {
        var check = MyService.ChkMail(x);
        check.then(function (d) {
            $scope.Valid = d.data;
        })

 }

Please use following -

$scope.CheckEmail = function () {
        var x = {
            Email: $scope.Email
        }
        if (x.Email.length >= 0) {
            var check = MyService.ChkMail(x);
            check.then(function (d) {
                $scope.Valid = d.data;
            })
        }

Hope this will work..

u need to access the Email property of the x object 

if (x.Email.length >= 0) {
 var check = MyService.ChkMail(x);
            check.then(function (d) {
                $scope.Valid = d.data;
            })
}
