・I am happy to hear that
・good for you!
・that was good news

「那真是太好了」除了可以用 I'm glad to hear that. 還能用I'm happy to hear that 或good for you! 等句子來表達。
另外要表達出「真是個好消息呢」這樣的細微差異，我認為即使用上 good news 也是不錯的。

I've been wondering about you since then, but you've resolved it. I am happy to hear that.
（從那時起我就一直想知道你的情況，但我想你已經解決了吧。那真是太好了。）

很開心能夠幫助到你。
