Use a workflow to send every new lead straight to a Klaviyo list. You build a Lead trigger, connect a landing page, add a Klaviyo action, map your fields, then publish. No code required.

​
Prerequisites

Before you start, make sure you have:
  • A LanderLab account with at least one published landing page
  • A Klaviyo integration already connected in LanderLab
  • The Klaviyo list you want leads added to
If you have not connected Klaviyo yet, set it up first. See Connect Klaviyo to LanderLab.

​
Step 1: Create the Lead trigger

Every workflow starts with a trigger. The Lead trigger fires whenever a new lead is captured.
1

Open the workflow canvas

Create a new workflow and give it a name (for example, “Klaviyo”). The canvas opens with a single + button in the center.
2

Add the Lead trigger

Click + and select the Lead trigger. It is added to the canvas and triggered when a new lead is captured.

Step 2: Connect a landing page

The workflow will not run until a landing page is linked to the Lead trigger.
1

Open the trigger settings

Click the Lead node. Its settings open in the right panel.
2

Add your landing page

Under Landing Page, click Add landing page and select the page that should trigger this workflow on every new lead.
Select Landing Page
A warning icon stays on the Lead node until a landing page is connected. The workflow cannot run without it.

​
Step 3: Add a node after the trigger

Click the + below the Lead node to add the next step. You will see two groups:
  • Internal nodes for routing logic: Filter, If, Switch, Delay
  • Actions for sending data out, such as HTTP Request, Google Sheets, and Klaviyo
Add Node
You have two common paths from here:
  • Send every lead to Klaviyo: add the Klaviyo action directly.
  • Send only some leads: add a Filter node first to qualify leads, then add the Klaviyo action after it.
Use a Filter when you only want leads that meet a condition (for example, a specific country or a completed field) to reach Klaviyo. Everything else stops at the filter.

​
Step 4: Configure the Klaviyo action

Add the Klaviyo action and click it to open its settings in the right panel.
1

Name the node

Under General, set a Name to identify this step on the canvas.
2

Select your account

Under Account, choose your connected Klaviyo account.
3

Choose a list

Under List, select the Klaviyo list where leads should be added.
4

Map your fields

Under Field Mapping, check the LanderLab fields you want to send and choose the matching Klaviyo field for each one. Default fields include LL Lander URL, LL Visitor IP, LL Visitor User Agent, LL Submission Time, and LL Variant ID. Any custom form fields appear here too.
Klaviyo
Map the email field so each lead becomes a usable Klaviyo profile. Without it, leads cannot be matched to subscribers.

​
Step 5: Save and publish

Click Save to store your changes, then click Publish to make the workflow live. Once published, every new lead from your connected landing page is sent to your Klaviyo list in real time.

​
Troubleshooting

Confirm a landing page is connected in the Lead trigger settings and that the workflow status is Published, not Draft.
Open the Klaviyo action and check that the correct account and list are selected and that at least one field is mapped, including the email field.
This is expected when a Filter node sits before the Klaviyo action. Review the filter conditions to confirm which leads pass through.
