For example, if news that the ETF has been approved gets published, you immediately receive a text to your phone? Or Amazon accepting Bitcoin, etc. I don't want to miss a major price catalyst because I didn't happen to refresh Coindesk 50 times that day, so was looking to see if anything like this was available.
Even if there was I doubt you'd be able to tailor it so specific to when Amazon starts accepting it. You could use rs feeds but you're still probably just going to have to keep your ear to the ground in some way.
