There may be a slight delay in the e-mail generating, if so:
- Log in to your account and head to the 'my programs' page
- Find the program you're sending rubbish for.
- If you have active labels, select 'view shipping labels' as per the below image. You can then select an unused label to download.
If you don't have any active shipping labels, you'll see similar to the below image. Simply click 'get shipping label' to create and download a new one.
