To get the news 'directly and immediately', you need real time streaming news. The premier service is an expensive Bloomberg terminal.
Many years ago, I used to trade earnings announcements. I subscribed to Dow Jones Streaming News ($39.95 a month). I think that the first broker I used for this was Datek Securities (Ameritrade bought them 15+ years ago). Their subscription offered the ability to input 5 lists of 20 symbols, each list having a different color code. If news was released from one of these, the colorized symbol stood out as the news story scrolled down the page (all other stories were in white print). I stayed with Ameritrade for awhile until some years later I found out that if you parked $500 in a Scottrade account, DJ News was free.
I don't know what's out there now (other services and price) but with some Googling, you might find something more attractive than full price :->)
A free alternative is if your broker offers price alerts, bracket the closing price in both directions. You won't know what the news is but you'll certainly see the direction. And given that you don't have the time to read EA details, price may be all that you need.
