At Gumroad, we work hard to ensure every purchase is handled securely — from PCI (Level One) compliant transactions, to unique and trackable download links for every purchaser. Today, we’re taking this a step further with the introduction of our new PDF Stamping.
If you’re selling a PDF on Gumroad, you now have the option of including a beautiful stamp of the buyer’s email address on the cover of the PDF. Stamping your PDF will apply a special graphic as well as the email address of each unique buyer of your product to the top right of the first page of your PDF.
To enable PDF stamping, head over to the Product Edit page, click ‘File Options’ and select the ‘Stamp the PDF.’
