# MailerLite Integration

> Connect your MailerLite account to automatically manage subscribers from automation workflows.

The MailerLite integration lets your ChatRos automations add or remove customers from your MailerLite groups and manage their tags — automatically triggered by real conversations.

## Prerequisites

* A MailerLite account with at least one Group created
* A MailerLite API key (found under **Integrations → API** in your MailerLite dashboard)

## Connecting Your Account

<Steps>
  <Step title="Open Integrations">
    In your agent's sidebar, click **Integrations**. You'll see the integrations hub with all available providers.
  </Step>

  <Step title="Select MailerLite">
    Click the **MailerLite** card. Any existing integrations will be listed here.
  </Step>

  <Step title="Add New Integration">
    Click **Add Integration**, then fill in:

    * **Name** — A label to identify this connection (e.g., "Newsletter List")
    * **API Key** — Your MailerLite API key

    Click **Connect**. ChatRos will verify the key against your MailerLite account.
  </Step>

  <Step title="Integration Ready">
    Once connected, your MailerLite groups become available in any automation's MailerLite action node.
  </Step>
</Steps>

## Available Actions in Automations

Once connected, you can use four MailerLite actions inside any automation workflow:

| Action                | What it does                                                                                                                                  |
| --------------------- | --------------------------------------------------------------------------------------------------------------------------------------------- |
| **Add to Group**      | Creates or updates the subscriber then assigns them to the selected group. First and last name are set automatically from `{{customerName}}`. |
| **Remove from Group** | Removes the subscriber from the group (subscriber account is kept).                                                                           |
| **Add Tag**           | Applies a tag to the subscriber. Supports `{{variables}}` for dynamic tag names.                                                              |
| **Remove Tag**        | Removes a tag from the subscriber.                                                                                                            |

<Tip>
  All MailerLite actions are silently skipped if `{{customerEmail}}` is not available in the conversation. Make sure your trigger or an upstream form node collects the customer's email first.
</Tip>

## Using MailerLite in a Workflow

1. In the automation editor, add an **Action** node
2. Set the action type to **MailerLite**
3. Select the integration from the dropdown
4. Choose the sub-action (Add to Group, Remove from Group, Add Tag, Remove Tag)
5. Select the target group (or enter a tag name)
6. Save and activate the automation

For example, a **Conversation Started** trigger → **Reply with form** (collect email) → **MailerLite: Add to Group** workflow will enrol every new visitor who provides their email directly into your MailerLite group.

## Mailchimp vs MailerLite

Both integrations work the same way inside ChatRos automations. The main differences are on the provider side:

| Feature             | Mailchimp                      | MailerLite                |
| ------------------- | ------------------------------ | ------------------------- |
| Subscriber grouping | Audiences / Lists              | Groups                    |
| API authentication  | API key with datacenter suffix | Bearer token (no suffix)  |
| Sub-action naming   | Add/Remove from **List**       | Add/Remove from **Group** |
| Tag management      | Identical                      | Identical                 |

You can connect both providers simultaneously and use them in the same or different automation rules.

## Managing Integrations

* **Toggle Active/Inactive** — Pause a connection without deleting it. Inactive integrations are skipped during automation execution.
* **Delete** — Removing an integration that is currently used by an active automation rule is blocked. Deactivate or update the automation first.
* **API Key** — API keys cannot be updated after creation. To change a key, delete the integration and create a new one.

<Warning>
  Deleting a MailerLite integration is permanent. Any automation rules that reference it will fail until you update them with a new integration.
</Warning>
