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.
The email address will be listed in the bounce list when the recipient refuses or rejects the incoming emails from us. It is possible that your email service provider is blocking our emails.
Our servers will try several times to deliver the messages for a given time-frame, but if the delivery constantly fails, it will mark it as "old", "rejected" or similar, and it will store your recipient email address into our bounce list.
