The Audience Builder is where you create and manage reusable lists of people in Alta.

Unlike the Audience step inside a campaign, which is specific to one campaign, Audience Lists live outside campaigns and can be reused across multiple campaigns.

Think of the Audience Builder as the strategic layer above your campaigns.

It is especially useful for teams running:

From the left navigation panel, click Audience.

Select a source from the options at the top of the page.

Common sources include:

You can also click More Sources to access additional options, such as:

Give your audience list a clear name.

This will make it easier to find and reuse later.

Rename your list right away.

The auto-generated date-stamped name can become confusing once you have multiple lists.

After selecting your source and naming your list, Alta will take you into the Audience Builder.

This is where you define the criteria for the people who should be added to your list.

Anyone who matches your criteria will be added to the audience list.

There are two ways to define your audience criteria.

You can describe your audience in plain language, and Katie will help fill in the filters for you.

For example, you can describe the type of people or companies you want to target, and Katie will translate that into audience criteria.

You can also build your audience manually by adding filters.

Common filters include:

Manual filters are useful when you already know the exact criteria you want to use.

From an audience list’s detail view, you can manage the people inside the list.

Click Add People to return to the Audience Builder and add more people to the same list.

You can also combine multiple sources into one list.

For example, you can add people from:

This allows you to create one unified audience from multiple sources.

Select people in your list and click Enrich.

Enrichment runs in the background, so you can continue working while Alta completes the process.

Once enrichment is complete, Alta will notify you.

Enrichment can help add useful data such as:

You can export people from an audience list.

You can export:

Selection-based exports are capped at 1,000 people.

You can delete people from an audience list.

Deleting someone from a list only removes them from that list. It does not delete the person from Alta entirely.

You can launch a campaign directly from an audience list.

Go to the list you want to use for your campaign.

Click Create Campaign from the list’s detail view.

Alta will create a campaign with your audience already attached.

This means you can skip the audience-definition step and go straight to building:

The same audience list can be used for as many campaigns as you want.

You can enrich your audience with additional context that Katie can use to improve outreach messaging.

For example, enrichment can help add:

This helps Katie create more relevant and personalized outreach.

You can use Alta as an enrichment engine without creating a campaign.

For example, you can:

No campaign is required.

You can combine several audience sources into one unified list.

For example, you can blend:

This allows you to run one coordinated campaign across a combined audience.

Use descriptive names that explain the audience and source.

For example:

If you plan to reuse an audience, build it as an Audience List first.

This keeps your audience organized and makes it easier to launch future campaigns.

Before launching a campaign, enrich the audience to improve data quality and personalization.

This can help improve message relevance and campaign performance.

When combining multiple sources, make sure the audience still matches your campaign goal.

A larger list is not always better if the targeting becomes too broad.

Audience Lists in Alta allow you to build reusable groups of people outside of a single campaign.

Once a list is created, you can:

Using Audience Lists helps you save time, keep targeting organized, and reuse the same audience across multiple campaigns.
