Thanks for reaching out to Jotform Support. Our Spanish Support agents are busy helping other Jotform users right now, so 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, it might take a while until they're available again.
Now, coming back to your question, if you're trying to update the email address on your Jotform account, you’ll need to log in to your current account first. Once logged in, you can change your email address from your account settings. You can follow our guide on How to Change Your Account Email Address.
But if you are unable to access the account and no longer have access to your current email address in your Jotform account, you can fill out Jotform Account Recovery Form on our guide on How to Recover Your Jotform Account.
