Summary

The Audience page in Alta is where you build and store reusable lists of people — separate from any single campaign. You build a list once (from Social Signals, Trigger Events, CSV, ABM, or 50+ other sources), enrich and clean it, then launch as many campaigns as you want from it. This article walks through the full lifecycle.

Who this is for: Anyone who wants to manage prospect lists outside the Campaign Builder — typically RevOps, demand gen, or campaign owners running ABM or signal-based plays.

Before you start

You'll need permission to create audiences in your Alta workspace.
The Audience page is gated by the Audience Lists feature — if you don't see Audience in the sidebar, your workspace doesn't have it turned on yet.
For CSV imports, have a file with at least one identifier column (email, LinkedIn URL, or company domain) ready.

Step 1 — Create a new audience list

Open Audience from the Alta sidebar.
The top of the page shows three of your most-used sources plus a More Sources tile ("Expand your reach with 50+ sources").
Click the source you want to start from. Alta opens the Create Audience List dialog with a date-stamped placeholder name like Untitled Social Signals Audience May 21, 2026.
Rename it (recommended — date-stamped defaults pile up fast) and confirm.
Alta drops you into the Audience Builder for that source. Build out your criteria there; the resulting people land in the new list.

Step 2 — Manage the people in a list

From the Audience page, click any existing list to open its detail view. The detail view has three pieces: the title and Create Campaign button at the top, a top bar with bulk actions, and the people table below.

Add People

Click Add People in the top right to jump back into the Audience Builder and keep adding to the same list. You can layer multiple sources into a single list — for example, start with Social Signals and add a CSV later.

Enrich (background)

Select people in the table, then click Enrich. Alta queues an enrichment job in the background — you'll see a toast like "42 enrichments triggered. This may take a few minutes to complete." Enrichment runs asynchronously, so you can keep working while it completes.

The button is disabled when:

No people selected — pick at least one row.
Enrichment in progress — wait for the current run to finish.

Export to CSV

Click Export in the top right. If nothing is selected, Alta exports the whole list (under the current filter). If you have rows selected, only those rows export.

Constraints:

Selection-based exports are capped at 1,000 people — the button disables with "Cannot export more than 1,000 people" if you select more.
Export runs in the background. You'll get a toast when it's ready (or an error toast if it fails).

Bulk delete

Select people in the table and click the trash can icon in the top bar. Alta opens a confirmation dialog: "Remove X person from this audience?" with a destructive Delete button. Deletion only removes those people from this audience list — it doesn't delete them from Alta as people.

Step 3 — Launch a campaign from the list

From the list's detail view, click Create Campaign in the top right.
Alta scaffolds a new campaign with the audience pre-bound to this list — no need to redefine criteria.
Continue through the Campaign Builder as usual (Pitch → Touchpoints → Setup).

Tips and common pitfalls

Rename the list before you forget. The auto-generated Untitled <Source> Audience <date> name is useful for one minute and confusing thereafter. Rename as soon as you create the list.
Enrichment is async — don't refresh waiting for it. The toast tells you the queue count, but completion lands in the background. You can leave the page and come back.
Selection exports cap at 1,000. For larger pulls, either filter the list and export with nothing selected (full-list export honors the filter, not the 1,000 cap), or do it in batches.
Layer sources into one list. The same audience list can hold people added from multiple sources. Useful for unifying inbound + Social Signals + an event list into a single play.
Use the global DNC, not deletion. Removing a person from one audience list doesn't stop them from showing up in future campaigns. To block them everywhere, add them to DNC on the Knowledge page.
Audience lists vs the campaign Audience step. An audience list is reusable and lives outside any campaign. The Audience step inside Campaign Builder defines a one-off audience scoped to that campaign. When you click Create Campaign from a list, you're skipping that step and binding the campaign to the saved list.
