# MailerLite ESP
Verify & clean email lists within your MailerLite Subscriber list
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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.clearout.io/integrations/mailerlite/mailerlite-esp.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
