No question is stupid but we will give you a quick tidbit of philosophy on this one. I check my junk filter numerous times a day, for one reason. The junk filter is imperfect and sends important emails there all the time. If you are not checking it daily at least you could miss out on the chance of a lifetime whether it is a show, tour, licensing deal or whatever. For the 10 seconds of your life it takes to check it, and the life changing oppurtunity you may miss it makes it worth it to check it often. So the answer is – it is a good idea to always check junk filter whenever you check your email.
