You can use a seed list with your one-time or recurring campaigns. A seed list allows a marketer to upload a list of users (like internal users), and subsequently receive a copy of a message to each user in the seed list. The email will reflect the content sent to the first user in the campaign.
- Follow the same Customer List setup process but select "Seed list" as the option.

- Associate the Seed list to use with the campaign under advanced setting.
