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.
Upon checking your account and the forms, everything seems to be setup properly, although one of your notification is missing a Sender's Name.
I've also checked the two recipient email addresses that you have, our mail logs show no failed email attempts or errors, also they are not in our bounce list.
I believe the problem is the email service provider, both emails are in @sitehelp.org, the provider might be blocking our JotMail IP addresses and domain names. Please contact the service provider and whitelist the following IP addresses and domain names found in this list: http://www.jotform.com/help/145-Whitelisting-JotMails-IP-Addresses.
I hope this helps. Do let us know if this resolves the problem.
