To do something "avidly" means that you do it enthusiastically, you do it more thoroughly than you might otherwise because you enjoy it or have a great interest in it. To "avidly read the news" would mean you read through an entire newspaper (or news web site or whatever), or read news from many sources, and that you do this because you want to and not because you have to for some reason.
So I don't think "avidly" works in this context. You can't really "avidly receive something". You may be excited or happy to hear this news, but you can't "avidly receive" it because "avid" implies that you are actively doing something.
Words that come to mind are "I was overjoyed to hear ..." or "thrilled to hear ...". "I was happy to hear ..." is grammatically correct but seems weak in context. You could also try something more colorful, like, "I practically fell out of my chair when I heard ..." or "I was beside myself when I learned ..."
