This guide will help you to avoid your emails bouncing or going to the spam or junk folders: https://www.jotform.com/help/208-How-to-Prevent-Email-Bouncing-Related-Issues. 

If this still persists, I think that you would need to ask your email provider to white-list our IP addresses, you will find them on this link: https://www.jotform.com/help/145-Whitelisting-JotForm-IP-Addresses-and-Domains
