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 believe you are referring to this form: https://www.jotform.com/50125643564957
I checked the Auto Responder that you have configured for that form and it appears that you have your email address set in the Sender E-mail and the Reply-To E-mail fields.
I also checked your email logs and it was indicated that all your emails were successfully sent. Your email was not included in our bounce list either.
I would recommend changing the Sender E-mail to firstname.lastname@example.org and your issue should be resolved. It is possible that having the same email in both fields are causing a glitch with your notification. Even though they are marked as sent, it appears that they are not being delivered to the user. Do give this a try and let us know the outcome.
