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.
Thank you for contacting us.
Our servers try to send the email messages for a several times and if the delivery of the emails keep failing to these email addresses, it will mark it as rejected and the system will store your recipient email address in our bounce list.
Kindly have a look at the user guide below that will guide you how to prevent email bouncing related issues.
Additionally, you can set up your own SMTP for your forms, instead of JotForm's servers, to prevent email bouncing.
Hope these help. If you need further guidance, please let us know.
