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.
This is probably due to recent issue with our email sytem. You can see the announcement about this in our forum headline message https://www.jotform.com/answers/
But latest I checked, your email is no longer in the bounce lists. So, it should be fine by now.
To make sure it does not get bounce listed again, apply the firstname.lastname@example.org as the Sender E-mail in your form notification emails and enable the Reply To field.
Please inform us if issue persist.
