This is different from '拝啓' (haikei). '拝啓' is a normal formal start. It always has season greetings. It is also different from '前略' (zenryaku). '前略' also skips greetings. But it does this to be brief or friendly. '急啓' means there is an emergency. It is much stronger than '前略'.
Don't use this when you are speaking. You also need to use a simple ending for your letter. For example, don't use '敬具' (keigu).
Use this when you want to say something important right away. It tells the person reading that your message is urgent. You can skip the usual polite greetings.
