How to Integrate MailChimp with Pearl Diver

By integrating Pearl Diver with MailChimp, businesses can leverage Pearl Diver leads to target high-value prospects. This enables you to run highly personalized email marketing campaigns and retarget visitors based on behavior and intent data collected on their website.

✅Prerequisites

Before configuring the MailChimp integration, ensure the following are in place:

An active MailChimp account set up and valid login credentials
Ensure you have connected an audience for the data you would like to send through the MailChimp integration, and this audience has the 'MailChimp' action selected

Step 1: Authorize MailChimp Integration

Log in to your Pearl Diver dashboard
Click the + icon next to Actions on the right hand side of the dashboard home page
Click on MailChimp in the left hand panel
Click Authorize - this will prompt you to log in to your MailChimp account

Step 2. Log in to MailChimp Integration

A new window will open to authorize your MailChimp account

🔓The Pearl Diver integration asks permission to access MailChimp data to allow Pearl Diver to create the fields detailed below. The integration will never delete contacts.

Upon successful authorization, a default Many-to-1 audience mapping is saved automatically.

Handling Audience Mapping Switch from Many:1 to 1:1

When switching from the default Many:1 mapping to 1:1 tag-based mapping, each Pearl Diver audience will be associated with a unique Mailchimp tag within the same Mailchimp list.

Switching from Many:1 to 1:1

Go to the Actions page in Pearl Diver.
Select the Mailchimp integration card.
In the Mapping Settings dropdown, change the mode from Many:1 to 1:1 (Tag-Based Mapping).
Click the Update button to confirm the change.
A success toast will be shown confirming the mapping switch.

What happens next?

In the next sync Pearl Diver will check for existing Mailchimp tags.
For each audience, that created or updated in last 30min, a new tag will created using the format:

PDV | [Audience Name]

(Only if the tag doesn't already exist.)
All future syncs will tag contacts based on their audience membership.

📌 Tag Sync Behavior – Important Rules

Scenario	Will Tag Be Applied?
Existing contact already synced before the mapping update to 1:1 and there is no audience update	❌ No tag applied Proposed solution: resave the audience.
New contact added to an existing audience	✅ New contact tagged with: PDV \| [Audience Name].
Audience is updated (e.g., contact list changes)	✅ All contacts tagged in Mailchimp as: PDV \| [Audience Name].
New audience created in Pearl Diver	✅ All contacts tagged in Mailchimp as: PDV \| [Audience Name].
