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

1

Open Integrations

In your agent’s sidebar, click Integrations. You’ll see the integrations hub with all available providers.
2

Select MailerLite

Click the MailerLite card. Any existing integrations will be listed here.
3

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.
4

Integration Ready

Once connected, your MailerLite groups become available in any automation’s MailerLite action node.

​
Available Actions in Automations

Once connected, you can use four MailerLite actions inside any automation workflow:
ActionWhat it does
Add to GroupCreates or updates the subscriber then assigns them to the selected group. First and last name are set automatically from {{customerName}}.
Remove from GroupRemoves the subscriber from the group (subscriber account is kept).
Add TagApplies a tag to the subscriber. Supports {{variables}} for dynamic tag names.
Remove TagRemoves a tag from the subscriber.
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.

​
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:
FeatureMailchimpMailerLite
Subscriber groupingAudiences / ListsGroups
API authenticationAPI key with datacenter suffixBearer token (no suffix)
Sub-action namingAdd/Remove from ListAdd/Remove from Group
Tag managementIdenticalIdentical
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.
Deleting a MailerLite integration is permanent. Any automation rules that reference it will fail until you update them with a new integration.
