JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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.
It looks like your email service provider has blocked JotForm IP address/email address and the emails sent to this email address are not delivered. Please try whitelisting JotForm IP addresses/email address to your email so that the emails should be sent normally. I have removed the email address from our bounce list as well.
We also request you go through the guide below that can help you with troubleshooting email delivery issues.
Hope this information helps!
