Can you please give me some insight regarding security of our forms?

Hello.  We have a document created by JotForm on our website.  When the clients complete it and hit submit, it is emailed to me.  A client questioned how secure this was as we are asking for account numbers and other sensitive information.  I did not set this up initially and that person no longer works for us.  Can you please give me some insight on this?  And if it is not secure, how can we make it so?  If you want to see what and how we use it, you can go here:  https://wilsonlawgroup.com/client-confidential-disclosure/

Thank you for your help.
