Emails marked as spam share list of IP for us to whitelist Jotform?

I work with SIUE and we have our Graduate department that has surveys setup with you.   The emails are being spoofed as ours so our system is marking them as spam.   I need a range of IPs of your Email domain so I can add it to the allow list. 

To whitelist Jotform IP addresses and domain names, kindly find list of IPs and Domain names in the guide below:

Kindly do let us know if you need further assistance

Thank you Trevon,   I found this not long after I posted this up.   I just couldn't find my way back here to say something.
