Reply to a Resolved Answer if no email?

I've received some "Resolved - Best Answer" votes but in a couple of them, the person who asked the question says "thanks" and then adds a question wanting more clarification. If they don't have email enabled in their profile, is there any way to reply to them?

They were wanting you to add while the question was still open. Users forget, most answerers do not recheck questions. As to responding now, you only option is to add a comment under the resolved question. There is no notification, so the asker will most likely never see it.
