Email Notifications have Stopped

I have been using Jotform for my website www.northpacificproperties.com  Every once in a while, the form forwarding shuts down.  So I am getting all of these leads in jotform but they are not being sent to me.  Your website has randomnly shut this feature down on my twice.  Last year it cost me a lot of money and I just realized that it did it again.  Please tell my why this keeps happening?  you probably don't care but I have to look into another platform. this is a joke.
