A combination of the sentence fragment, and thinking it might have been IM speak as roryokane suggested. "2-click" instead of "2 click" would do a lot to clear that up. I definitely didn't pick up what you meant, but now that its been explained it seems obvious. For maximum clarity, I would change it to: "We only send email when your site goes down. Unsubscribe in 2 clicks."
