We used Earthclass mail and it did everything it said it was and we were pleased with the service. The alert you when mail is delivered, you can choose to discard, recycle, scan, or keep whatever you wish. They will forward on whatever you wish. This is where it gets expensive. I was having several pounds (financial statements, magazine, etc.) forwarded on to me and it cost roughly $75 every time.
So I now read my magazines and most financial statements online. Everything else is sent to a family member who alerts us when something “official looking” arrives. And then we just have her open it and tell us what it’s all about.
