# Connect Mailchimp

Add Darwin chat leads to a Mailchimp audience through Zapier: Darwin's New Lead trigger and Mailchimp's Add/Update Subscriber action, with double opt-in and a Darwin chat tag.

Find it in Darwin: Integrations → CRM & automation → Zapier (https://app.meetdarwin.ai/admin/settings/integrations/zapier). Updated Oct 13, 2026.

Add leads from Darwin's chat to a Mailchimp audience, tagged so you know where they came from. This runs through Zapier: Darwin's Zapier app starts the Zap and Mailchimp's Zapier app does the work.

**You need:** A Zapier account (the free plan works for this two-step Zap) and a Mailchimp audience to add people to.

1. **Add Darwin to Zapier**

   In Darwin, open **Integrations** and select **Connect** on the **Zapier** card. Select **Add Darwin to Zapier** (1) while signed in to Zapier and accept the invite. Darwin is in private beta on Zapier, so the invite adds it to your account.

2. **Create a key for Zapier**

   Select **Create key** (2). In **Integrations → API**, name the key **Zapier**, select **Choose** and tick the scopes Darwin lists, then select **Create key** and copy it. Darwin shows it only once.

3. **Start the Zap with Darwin's New Lead trigger**

   In Zapier, create a Zap. Choose **Darwin** as the app and **New Lead** as the trigger event. Connect your Darwin account by pasting the key, then select **Test trigger** to load a sample with the visitor's name and email when they leave them.

4. **Add Mailchimp's Add/Update Subscriber action**

   Add an action step. Choose **Mailchimp** as the app and **Add/Update Subscriber** as the action event, then connect your Mailchimp account.

5. **Map the fields**

   Pick your **Audience**. Map **Subscriber Email** → Email, **First Name** and **Last Name**, type `Darwin chat` in **Tag(s)**, and set **Double Opt-In** to **Yes**.

6. **Test and publish**

   Select **Test step** and check the result in Mailchimp. Then select **Publish**. Back in Darwin, **Build a Zap** lists the Zap with its event; **Open Zapier** manages it.

## Good to know

- Leaving an email in a chat isn't consent to marketing, so keep double opt-in on. The person shows as pending until they confirm.
- A second Zap on **Meeting Booked** can tag people who booked.
- Zaps act on new events from the moment you publish. Earlier leads are in **Conversations**, which you can export as a CSV.
- Chats in Agent Studio's preview never start a Zap. Test with a real chat on your website, or with the sample from **Test trigger**.
