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.
I have checked the email address that you're using as recipient in your form https://form.jotform.com/HAlfred/CAPSTONE and I can see it is in our bounce list, I have already removed it from there so you should receive emails now.
I would suggest you to check this guide in order to avoid bouncing: https://www.jotform.com/help/208-How-to-Prevent-Email-Bouncing-Related-Issues
If the issue still persists, please try setting up SMTP in your account so you have more control over the sender emails and IP addresses, this guide will help you with that: https://www.jotform.com/help/244-How-to-Setup-SMTP-for-a-Form
Hope this helps.
