Map Data Table rows for sends

Choose a stable row key, recipient address and optional subscriber key.

How to do it

  1. Open Marketing → Data tables and expand the target table settings.
  2. Select an existing text field as the unique primary key and an Email field as Send email address.
  3. Optionally select a text field as Subscriber key field and save; then create an Audience with this Data Table as primary object, preview eligible recipients and review the Send Flow.

Check your result

Imports with Update duplicates and Object Record API upserts match the primary key instead of the display name. The mapped email is selected when creating a new Data Table audience; a mapped key identifies the BU subscriber for that email.

Good to know

Subscriber keys must be unique within the BU. Existing different keys for the same email block the send until reconciled. Suppression and consent still apply; changing a visible key does not rewrite past delivery identity.
