    Why does my file upload email continue to end up on your bounced list!?

    Asked by cstwpb on March 08, 2017 at 08:54 AM

    My clients will receive a "thank you" after hitting the file "submit" button on my form after uploading a file, but it never ends up getting to my email box. When I then log onto my jotform acct I see a notification that my email was added to your bounce list. I have an option to change my email or to remove it from the list. Of course I choose to remove it, but I have to keep removing it! WHY? I can't constantly monitor your site for my email to work! Please let me know if there is something more that I have to do or is there something going on on your end.


    Thank you for your help.

    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-AddressesYou 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
