What's the dif between instant e-mail notification and daily?

I like to keep up with a thread, and when I post, I check the box marked “instant e-mail notification.” But it seems this only lasts one day. However, if I check “daily e-mail notification,” I think I’ll miss all the posts today, until I get one notification that alerts me to them all. How do I get what used to be continual notification that a thread is growing, even over several days? xo C.
