How Can Leads Submit Forms Without all the Required Information?

Version 2


    I have leads that are getting created without providing information for fields which I have made required.



    Marketo's field validation makes use of javascript. Most browsers have javascript enabled by default so this should be fairly rare, but a user could change their settings and turn javascript off. This would allow them to submit a form without providing all the required information. There is also the possibility that leads are using an outdated browser. All browsers read javascript differently, and some outdated browsers are not equipped to read new forms of javacsript. You can learn more about our supported browsers here.
