Email Signature

I am not sure if I have understood your question correctly. We have received an empty question from you with just the title as "Email Signature".

Do you mean to say that you want your users to be able to sign in form and then you want to receive it in submission email?

Yes it is possible to achieve your requirement by adding "Signature" widget in form. The following guide should help you how to add signature in form:  https://www.jotform.com/help/433-How-to-Add-an-E-Signature-to-Your-Form

Once your user sign in form, you will receive submission email including signature.

Hope this helps.
