Overview
1/2
Unify email and customer insights across Mailchimp and HubSpot for information alignment and reduce the need for messy, time-consuming imports.
Install this app to:
Sync contacts and records between Mailchimp and HubSpot two-ways in real-time for data alignment
Get set up quickly with automatic historical data sync and configure ongoing sync settings to reduce manual data management and prevent data silos.
Configure custom field mappings between Mailchimp and HubSpot contact properties to match specific business requirements.
Note: To sync Mailchimp email activity - including sends, opens, clicks, and bounces - to HubSpot timelines, create segments and build lists, or use email engagement to trigger automated HubSpot workflows, you’ll need to install an additional Mailchimp app. You can do so here.
Features
Sync Mailchimp and HubSpot in the background
Make manual data entry a thing of the past by syncing data (see below) between HubSpot and Mailchimp. When records are created or updated in either app, that information will be automatically shared with the other one. You can also add a filter for any Mailchimp field or HubSpot list to sync exactly what you want—and nothing you don’t.
You’re in control of your data
You can set up a one- or two-way sync, which means you can either sync data from Mailchimp to HubSpot, from HubSpot to Mailchimp, or back-and-forth! IMPORTANT: This app requires Data Hub Starter or above.
App Functionality
Shared Data
Each object has field mappings that connect matching information from each app.
The following will not sync: Groups, Tags, Email Opens/Clicks. As mentioned above, you can review and install the other Mailchimp integration here to sync additional data.
Note: You will need Data Hub Starter and up to use this app.

While users report that the tool transfers only email addresses without names and occasionally merges lists incorrectly, some appreciate the quick setup for basic contact syncing. A few reviewers praise the intuitive interface for managing mass communications, though others mention that unsubscribes and custom tags do not always map back to the main database.

Still new but so far I like it
This is a new integration for us but contacts seem to be flowing in from Mailchimp pretty seamlessly. One thing I need to determine is how to automate the lead status to the correct default. Not an obvious configuration when I set it up.

Helpful add-on
It's making it easy to keep contacts updated
Time saving. Stops new contacts slipping through without being added to contact lists
