Form Submissions no longer going to my business email

We were using Gravity Forms via Wordpress for a while but for some reason when potential customers fill out our form and hit submit, it no longer sends their info to our email.

We have 3 forms: Enrollment, Contact Us, and Schedule a Tour, the schedule a tour is the main one we use to get customers.

Anything we can do? Is it possible to make the form more basic? Meaning not having to utilize gform but instead basic html/css/javascript? It’s just basic info we need.
