I have been using their service for two years now. They make it easy to forward your mail to another address so that you never miss a receipt. You only get one notification which gets pushed out once a day. It's not possible to set multiple addresses or have them notified separately. Some people may find this frustrating. I like that I don't have to go through my mailbox every time I want to see what bills I've received. I used to do that all the time! Just forward those bills to me. I also use it for things like shipping invoices. Again, just forwarding my invoices to me is much simpler than having to open each one individually.
