How to get HTML code of form and use it outside JotForm?

If I create a HTML email campaign using JotForm, am I able to extract that HTML code and use it for creating an email campaign outside of JotForm?

I am not sure if I have understood your question correctly. Do you mean to say that you want to use the same form outside JotForm?

Please note that you can download your form's full source code and change the code to read the form data and save it in your own database. This will require some programming exposure to achieve this. The following guide should help you how to download your form's full source code:  https://www.jotform.com/help/104-How-to-get-the-Full-Source-Code-of-your-Form

Hope this helps.
