You have that feature before until the time I noticed that I received an attachment zip folder on my email but without files in it.
So I decided to purchase the plugin’s paid version expecting to fix this error but it’s totally gone now.
Ah I see, the uploaded images are sent to email definitely, I thought you are looking to receive all meta fields in zip as an attachment. Please send me your product page URL so we can checkout and see why uploaded files are not being sent with email with download link.
