Rules: use a View's result as a condition? How can I use the results of a view as a condition in a rule?

I have rule that fires off a daily digest email with contents from a view (using Views Rules). The view simply returns nodes that have a specific field value. When the view doesn't return any nodes, the rule still fires off what is essentially an empty email. I want to prevent this. I need a condition like "View has no results" (negated)… but I don't see anything like that. What's the workaround?
Even though your own answer is indeed a way to solve your question, it doesn't say that for this to work, it requires the Conditional Rules module to be enabled (without that, you cannot add a Rules Condition as an extra rules Action).

An alternative solution to solve your question, is to use the Views Bulk Operations (VBO) module to transform your view into a VBO view, so that you can use a Rules Condition "Check number of results returned by a VBO View" in which you can perfectly construct the Rules Condition you're looking for.

Have a look at "this answer" for an illustration of how this specific Rules Condition is used.

PS: I'm assuming this question is about D7.
