How to require professional email address on Form-block submissions?

Site URL: https://happyreturns.com/frp-business-email-test

I would like to prevent visitors from submitting forms with their personal emails.

I know that some other website and form solutions offer this (usually by running a script that references the "Freemail" list), but I am not quite sure how to properly implement such a script on my own page. I have implemented a fair bit of custom code on other websites in the past, but nothing like this. 

I have been receiving submissions of similar forms on this website that have contained personal emails, and it is making organization within our CRM system a bit cumbersome. I found a similar thread within the Marketo forums, but I am unsure how to adapt their code snippets for use on Squarespace with the Form-block. 

Any help is greatly appreciated!

Do you want to prevent when users input the email filed or when they submit your form?

@bangank36 Either one would be wonderful. We just want to prevent receiving personal emails in the form submission, so whichever method is most reliable (or recommended) is something I'm willing to try. 

Did you find a solution to this? 

I'm also looking to do this. Has anyone found a solution?
