what is a bounce list

If your notifications are not coming through, your email address might be on our bounce list. You can remove it by yourself, by following the instructions provided at :

https://www.jotform.com/help/262-How-to-Remove-Your-Email-Address-from-Bounce-List

This usually happens when the messages are rejected by your email service provider. 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 in our bounce list. To prevent email bouncing related issues please read :

In addition, you can find our mail server domain list from this guide: https://www.jotform.com/help/145-Whitelisting-JotMails-IP-Addresses. You may consider adding the list on your whitelist settings. 

If the issue continues, our best recommendation to avoid email bouncing issues is to use your own SMTP settings for the sender email: https://www.jotform.com/help/244-How-to-Setup-SMTP-for-a-Form
