It's possible to send files uploaded via your form as attachments in your emails
When someone uploads files via your forms they’re added as links to the notification email you receive upon submission.
You can however enable the setting
Send uploaded attachments with the email which will attach the files
to the email that you receive.
To make this work for most email clients, we'll only attach files that are smaller than 10MB and once the total size of your email hits 30MB we'll not attach anymore files. They'll still be linked in the email itself.
