How do I reinstate email addresses that are currently blocked as spam?

I inadvertently hit spam when I meant to hit move for some emails regarding a specific project. Now emails from those addresses don't even show up in my spam folder, they are completely blocked, what do I do to reinstate them...if I can at all?
