This one sends notifications too: https://www.secinfo.com/ You have to go to My Interests section and choose which tickers you want notifications for and then open the filing page and turn on notifications by clicking on the toggle. The other one I gave you always sent notifications but I was looking at it and even though the home page says "setup free filing alerts" I don't see where they allow you to do it. If you too weren't able to find it there you can use this other one.
