    <div class="tip-text"><p><strong>This Audiences feature leverages the Reverse ETL workflow.</strong></p>
<p>To build targeted, no-code audience segments from warehouse data and activate them downstream, use <a href="https://www.rudderstack.com/docs/activate/lookout/" >Rudder Lookout</a> instead.</p>

<p>RudderStack’s <strong>Audiences</strong> lets you create target customer lists or a subset of users satisfying specific criteria with easy-to-use filters on your warehouse tables. Once <a href="https://www.rudderstack.com/docs/activate/audiences/create-audience/" >created</a>, you can connect and activate them in the <a href="https://www.rudderstack.com/docs/activate/audiences/supported-destinations/" >supported destinations</a>.</p>
<p>For example, you can create an audience and send that data to the downstream digital advertising destinations to:</p>
<ul>
<li>Retarget all users from a specific city/state/region to improve repeat sales.</li>
<li>Prompt active customers on your sports website to buy season tickets.</li>
<li>Run campaigns to grow product usage and retain users.</li>
</ul>

<h2 id="key-features">Key features</h2><p>RudderStack provides audience-building capabilities in its Reverse ETL pipeline where you can:</p>
<ul>
<li>Create and sync a single audience to multiple downstream systems, which is very time-consuming to do manually.</li>
<li>Analyze the results of multichannel campaigns in a single place at the data warehouse.</li>
<li>Trust the audience data as a single source of truth and have complete control over the ecosystem.</li>
<li>Fast-track the process for marketing teams who would otherwise need to work with SQL and warehouses or rely on data engineers to query and sync audiences.</li>
<li>Avoid updating the audience every time or debugging issues while building audiences using proprietary tools, saving time.</li>
</ul>
