I finally found out how to fix your issue. You need to use the Jsonp support of Angular2.

Your address supports Jsonp by adding a c query parameter to your URL and switching https://mysubscriptionlist.us10.list-manage.com/subscribe/post by https://mysubscriptionlist.us10.list-manage.com/subscribe/post-json. You need to put the JSONP_CALLBACK value in it (see this issue: https://github.com/angular/angular/issues/5613).

In this case, you will have the following response payload:

JSONP_CALLBACK (
{
  "result": "success",
  "msg": "Almost finished... We need to confirm your email address. To complete the subscription process, please click the link in the email we just sent you."
}
)

After having registered JSONP_PROVIDERS when calling the bootstrap function:

import {bootstrap} from 'angular2/platform/browser'
import {JSONP_PROVIDERS} from 'angular2/http'
import {AppComponent} from './app.component'

bootstrap(AppComponent, [ JSONP_PROVIDERS ]);

You can then execute your request using an instance of the Jsonp class you injected from constructor:

import {Component} from 'angular2/core';
import {Jsonp} from 'angular2/http';

@Component({
  selector: 'my-app',
  template: `
    <div>
      Result: {{result | json}}
    </div>
  `
})
export class AppComponent {
  constructor(jsonp:Jsonp) {
    var url = 'https://mysubscriptionlist.us10.list-manage.com/subscribe/post-json?u=(...)&subscribe=Subscribe&EMAIL=my@email.com&c=JSONP_CALLBACK';
    jsonp.request(url, { method: 'Get' })
     .subscribe((res) => {
       this.result = res.json()
     });
  }
}
