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.
I took a look at your jotforms and I do not see any submissions made on them. This would explain why you did not get any emails.
However since you have mentioned that they are blacklisted, can you please tell me what is the service that you are using that has notified of our emails being blacklisted? From what I can see your emails are set to be forwarded to your Microsoft Outlook WebMail account, are they reporting this? This would help us to see why they would blacklist us and to resolve it.
