# MailerLite ESP
You must verify your Mailerlite email lists so that you can maintain and improve your email deliverability. This Clearout integration of **email verification with Mailerlite helps ensure that invalid and fake email addresses** are filtered out from your list before you hit send. Securely import/export data between the two platforms using the email validation integration.

{% step %}
### Connect account
After logging in to your Clearout account, go to the **Integration page** and select **MailerLite**.
Click on "**Add Account**" to add your MailerLite account. A pop-up will be displayed asking for the **API Key and Account Name**. You can find these details in your MailerLite account in
“Account Integration **→** Developer API **→** API Key“.
Once you feed in the Key details in Clearout, click on the "**Add Account**" button.
{% endstep %}
{% step %}
### Add the email lists
Keep the email address lists clean by easily adding them from the MailerLite account.\
\
Once you've successfully logged in, **select the list(s)** you want to verify from the associated MailerLite account.
{% endstep %}
{% step %}
### Verify the email address list
Once the mailing list is successfully added, click on the "**Verify**" button to start validating the added mailing list.
{% endstep %}
{% step %}
### Export the verified results
Once the email validation is complete, the user can either **download the result** (in .CSV, .XLSX) or **directly export** it to the MailerLite account.\
\
The user can export the result by selecting either "**unsubscribe**," "**append**," or **both**.\
\
**Unsubscribe:** By choosing this option, you can unsubscribe from the invalid/non-deliverable email addresses on the MailerLite list automatically, which removes all the non-deliverables from the mailing list.\
\
**Append:** By choosing this option, you can export the result and append the Clearout columns with the original file in the MailerLite account.

```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
