How to block a specific email from submitting

¿Se puede bloquear una direccion de mail para que no pueda enviar formularios?

Hi Jaime,

Thanks for reaching out to Jotform Support. Unfortunately, our Spanish Support agents are busy helping other Jotform users at the moment. I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Spanish, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

Now, In regard with your question.  I’ll need a bit of time to look into this. I’ll get back to you as soon as I can.

Thanks for your patience, we appreciate it.

Hi Jaime,

We really appreciate your patience and understanding while we’re looking into this. We currently have no feature to directly block a specific email from submitting your form. But, as a workaround for that, you can create a condition to prevent a specific email from submitting the form. If one enters an email address that you want to block, you can hide the Submit button to prevent submitting.  Let me show you how using a demo form:

1. In Form Builder, click on Settings at the top.

2. Click on the Conditions tab, then select Show/Hide Field from the options.

3. Next, set up this recommended condition then after click on the Save button.

That's it! View screencast below to see how it works:

Give it a try and let us know if you have any other questions.

ok thank you!

Thank you very much for the response. I have solved it by adding a Math Captcha to the form.
