JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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.
Unfortunately, it is not supported to attach the documents or other files to notifications. Instead we are providing a link to download the file uploaded to your form submission. It is to prevent abusive users from hogging up server resources, since we allow attachments upto 1GB and allowing multiple users on each notification.
I have checked your JotForm and see that the notification is already having the upload field. Also, I notice that you are receiving the link to download the file uploaded in the notifications.
Hope this information helps.
We are pleased to inform you that you can now have the file uploads as attachments in your email alerts. You can learn more about it on this blog post https://www.jotform.com/blog/223-New-Feature-Get-Uploaded-Files-as-Email-Attachments
We hope you will like it.
