Sometimes the audience is decided outside Lobyco — a list from a partner, a store’s own selection, a one-off export. The Seed block takes a file of customer IDs as the campaign’s input, in place of a Member Segment block.

What you’ll build

​
Steps

1

​
Start a new campaign

Open the Campaigns tab and select Add new campaign.
2

​
Add a Seed block and set it to file mode

Upload the file of customer IDs. See Block reference.
3

​
Add a Split block and connect it to the Seed block

In this example the imported customers are grouped by age.
4

​
Run the campaign

Wait for the execution to finish, then download the outcome and check the results.
A Seed block replaces the Member Segment block as the campaign’s input — it does not sit after one.
Migration note. Rewritten from Segmentation > User exercises > Import file with members ids for campaign configuration.
