How can I stop receiving emails from JotForm news?

Can you provide us more details regarding the issue you are encountering? I checked your account angelsandemons and I only see one form under the account (http://www.jotform.us/form/72598015042151). Currently, the form has only one submission. 

The emails are from the Jotform company, not from the form

You're receiving those emails due to the account you have created, it's an attempt to let you know which is new on JotForm; however, we could unsubscribe your email so you do not receive those emails, please  let su know if you would like that. 

We will wait for your response.
