Many websites targeting the "SuperMailer license key" market do not provide a file download at all.

This data is collected by threat actors to commit identity fraud or sold on the dark web. 3. Compromised Email Deliverability

You can use the SuperMailer Freeware version for free if you have up to 500 recipients. This is ideal for private individuals or non-profit associations.
