## What is MailerLite and Why Use This Integration?

MailerLite is an email marketing platform used to build subscriber lists, send campaigns, and run automations. When you connect MailerLite to a LanderLab landing page, every lead that submits your form is instantly added as a subscriber in MailerLite, assigned to the groups you choose, and ready for your email sequences without any manual import.

<Note>
  MailerLite integrations **are saved globally in your account**. Once you add your MailerLite account, you can reuse it across multiple landing pages without entering your credentials again.
</Note>

2. Go to **Integrations** in the left sidebar
3. Click **API** under the Developer section
4. Copy your **API token**

## How to Add MailerLite

The MailerLite setup uses a 3-step wizard: connect your account, configure groups and field mapping, then review before activating.

### Step 1: Connect Your MailerLite Account

<Steps>
  <Step title="Go to your landing page">
    Navigate to **Landing Pages** and click the **name of the landing page** where you want to add MailerLite.
  </Step>

  <Step title="Open the Integrations tab">
    Click **Add Integration** to open the integrations panel.
  </Step>

  <Step title="Select MailerLite">
    From the list of available integrations, find **MailerLite** (labeled as "Send leads to MailerLite in real time") and click on it. The setup wizard will open.
  </Step>

  <Step title="Fill in the connection details">
    Enter the following:

    | Field       | Description                                                                                                    |
    | :---------- | :------------------------------------------------------------------------------------------------------------- |
    | **Name**    | A label to identify this integration (e.g. "MailerLite - Auto Insurance"). Helps you recognize it in the list. |
    | **API Key** | Your MailerLite API token. Paste the key you copied from your MailerLite account.                              |
  </Step>

  <Step title="Click Add MailerLite">
    Click **Add MailerLite** to authenticate and move to the next step.
  </Step>
</Steps>

***

### Step 2: Configure Groups and Map Your Fields

This step has two parts: selecting which MailerLite groups new subscribers should be added to, and mapping your form fields to MailerLite subscriber fields.

<Steps>
  <Step title="Select your Groups">
    In the **Groups** field, search for and select one or more MailerLite groups. Every lead submitted through this landing page will be added as a subscriber to the groups you choose here.

    <Note>
      Groups must already exist in your MailerLite account. You cannot create new groups from this step.
    </Note>
  </Step>

  <Step title="Click Continue">
    Click **Continue** to move to the field mapping screen.
  </Step>

  <Step title="Map your form fields to MailerLite fields">
    You will see a list of all fields from your landing page form on the left, and a dropdown to select the matching MailerLite subscriber field on the right.

    | Form Field          | MailerLite Field |
    | :------------------ | :--------------- |
    | Full Name           | Full Name        |
    | Email               | Email\*          |
    | Phone Number        | Select field     |
    | (other form fields) | Select field     |

    Map each form field to the corresponding MailerLite field. At minimum, map **Email** as it is required by MailerLite to create a subscriber. All other fields are optional.

    Fields you do not map will not be sent to MailerLite. Use the checkboxes on the left to include or exclude fields from the sync.

    <Tip>
      LanderLab also includes system fields like **LL Lander URL**, **LL Visitor IP**, **LL Visitor User Agent**, **LL Submission Time UTC**, and **LL Variant ID**. You can map these to custom fields in MailerLite if you want to store tracking data alongside subscriber records.
    </Tip>
  </Step>

  <Step title="Click Continue">
    Click **Continue** to move to the review step.
  </Step>
</Steps>

### Step 3: Review and Connect

<Steps>
  <Step title="Review your integration">
    The final step shows a full summary of your MailerLite integration:

    * **Name** - the label you gave this integration
    * **Configuration** - the MailerLite groups leads will be added to
    * **Field Mapping** - the form fields being sent and which MailerLite fields they map to

    If anything looks wrong, click **Back** to return to the previous steps and make changes.
  </Step>

  <Step title="Click Connect MailerLite">
    Click **Connect MailerLite** to save and activate the integration. From this point on, every lead submitted on this landing page will be sent to MailerLite in real time.
  </Step>
</Steps>

## Tips for MailerLite Integration

* **Email is required** - MailerLite cannot create a subscriber without an email address. Always map the email field, and make sure your form includes an email input.
* **Map Full Name carefully** - MailerLite stores first and last name separately in some setups. If your form collects a single Full Name field, map it to the Full Name field in MailerLite, or split it into separate fields in your form if your MailerLite setup requires it.
* **Use groups to segment leads** - Assign different landing pages to different groups in MailerLite to keep your subscriber lists organized by campaign, traffic source, or offer.
* **Test with a real submission** - After connecting, submit a test lead using your landing page and verify the subscriber appears in your MailerLite account within a few seconds.
