# Send visitors to Smartlead

> Add identified Squid ID visitors directly to a Smartlead campaign through its API, with ICP routing, requirements, and Squid ID+ data. No Zapier required.

[Smartlead](https://smartlead.ai) is a cold-email platform for running outbound campaigns at scale. Squid ID identifies the person on your site and adds them straight to a Smartlead campaign through Smartlead's API, so they enter the sequence automatically. This is a direct integration, so you don't need Zapier in the middle.

## If you're coming from RB2B

RB2B can sync to Smartlead, but it adds everyone and leaves the targeting to you. Squid ID adds only the visitors that match your ICP, with the work email as the lead and Squid ID+ data attached.

<div className="compare">
  <table>
    <thead>
      <tr><th /><th>RB2B</th><th>Squid ID</th></tr>
    </thead>

    <tbody>
      <tr><td>Connection</td><td>Native</td><td>Native (direct API, no Zapier)</td></tr>
      <tr><td>Who's added</td><td>All visitors</td><td>All, by ICP, or by high-intent page</td></tr>
      <tr><td>Requirements</td><td>Limited</td><td>Require company, LinkedIn, or work/personal email</td></tr>
      <tr><td>Premium contact data</td><td>Not provided</td><td>Mobile, personal email, address via <a href="/add-ons/squid-id-plus">Squid ID+</a></td></tr>
    </tbody>
  </table>
</div>

<p className="why"><strong>Why this matters.</strong> A campaign is only as good as who's in it. Squid ID enrolls just the on-profile visitors and hands Smartlead the work email plus, where unlocked, a mobile number and personal email to personalize with.</p>

## Connect Smartlead

  </Step>
</Steps>

## What's sent

The work `email` as the lead, plus `first_name`, `last_name`, `company_name`, `website`, `location`, `phone_number`, and `linkedin_profile`. Context and Squid ID+ data ride in `custom_fields`: `squid_icp`, `squid_is_icp_match`, `squid_job_title`, `squid_landing_page`, and, when unlocked, `squid_personal_email`, `squid_mobile_phone`, and `squid_home_address`.

<Info>The work email is the lead address. The personal email (when ID+ is unlocked) is a custom field, not the send-to address, so cold outreach goes to the work inbox by default.</Info>

## Pause or disconnect

* **Pause:** Use the toggle on the Smartlead card to stop sending without losing the key or settings.
* **Disconnect:** Open the connector and click **Disconnect**.
