What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Your email address is working and I don't see any problem with your settings. If you will check your email history, you'll see that we are sending you the form emails.
I would suggest checking your spam folder and make sure to whitelist our default sender email, firstname.lastname@example.org. If you have the option to whitelist a domain, please do for jotform.com.
One more thing, the form is integrated with Paypal. You have incomplete payments on the submissions page. Please check them and verify to make sure they are the submissions made by your clients.
For incomplete payments, this guide should help you: https://www.jotform.com/help/272-Paypal-Incomplete-Payments-FAQ.
Please get back to us if you need further assistance.
