I don't know if you

Hi. I don't know if you can help but I'm having a problem with email notifications - I'm not getting any! Every time a user fills out a form I'm supposed to get an email update. Despite having all the settings correct for my Caldera Forms plug in correct, I'm still not getting them, which leads me to believe there may be a wider problem. Is anyone able to take a look for me please? I've granted access vis the support portal.
