## Verify Apollo list  <a href="#wcq1p" id="wcq1p"></a>

After the list has been added successfully, click "**Verify**" to begin validating the Apollo list.\
\
You can opt to export the confirmed email list to their Apollo account once the email validation is done. The result may be exported, and the Clearout columns can be appended to the original file in the Apollo list. \

Once the export is completed, Clearout sends an export success email to the user.

## Apollo List Export Failure Due to API Limit

You might face the issue of failing to export the Apollo list due to the API rate limit if your existing plan doesn't support it.

There is an alternative to upgrading your Apollo.io plan:

{% stepper %}
{% step %}
Download the verified result file from Clearout.

## View Clearout Fields Using Apollo Filters <a href="#jq6ba" id="jq6ba"></a>

Go to Apollo '**List**', Click on '**More Filters**' & Navigate to '**Custom Fields**' to select the required Clearout Columns

Using the Apollo rule engine, you may automate this procedure as well. For each verified email list, go to settings, then rule engine, and configure the same procedures as an automatic job.

<div data-with-frame="true"><figure><img src="https://93738666-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FEXQQW0hsXyH0YD4ePoxb%2Fuploads%2FJwQt6CMG67civ9NYNTie%2Ffilter%20configuration-apollo.webp?alt=media&#x26;token=c9a5d36f-3985-4af8-b307-6557befe84e3" alt="Enable Custom Field on &#x22;More filters&#x22; to view Clearout Result Fields"><figcaption></figcaption></figure></div>

You get to see various Clearout standard columns, and you can pick the ones you need. We recommend choosing the "**safe to send**" option for the highest deliverability rate or selecting emails categorized under the "**Valid**" status.
