One of our moderators was having a problem and it turned out to be Outlook. Everything from here was going into the spam folder. He reloaded using the Repair option and it's working fine now.
In other words, Lee is right, the problem is on your end. If you list what you are using, computer vs cell phone vs tablet, operating system, Windows vs Apple vs Android and what email program, maybe we can provide more help. Otherwise we can only guess, and I'm not good at guesses.
