You can create a blockchain.info wallet and import a list of addresses as "watch only". They will email you when funds arrive and leave those addresses. Because you are not importing a private key, just addresses, there is no risk of loosing your coins.
I have been considering this myself to keep track of the funds over there but after the "satoshi coins moved!" incident on blockchain.info im not sure if I can trust that site anymore. What are the best alternatives nowadays?
There used to be a few similar services, most of them have shutdown. Blockchain.info is the only one I know of that is still working. You don't need to trust BC.i, it's just a notification. You can always verify your address on other blockexplorers. I have been using them for more than 2 years and their email notification has been spot on.
