Overview
1/2
Sync Mailchimp contacts without manual data entry or messy, time-consuming imports. Here’s what you get with Data Sync by HubSpot:
Two-way sync: Data is shared between Mailchimp and HubSpot in real time
Historical syncing: Your existing data will sync right away, and updates will sync as they happen
Custom field mapping: sync fields other than email, first name and last name
This sync can be used on top of this other Mailchimp app that syncs Mailchimp events to your timeline.
Note: This app requires at least a subscription to Data Hub Starter. See below.
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.

Disastrous migration that mixed up all my databases and erased critical contact information
When connecting to Mailchimp and migrating the databases, it did not do it right, it merged them all into one and the contents of important fields such as name and surname disappeared.

Seamless integration that keeps everything organized, though lead conversion could be smoother
Using HubSpot with Mailchimp saved a lot of time for me. The connection made it simple to move all my newsletter subscribers from one place to another without any headaches. I liked that I didn’t have to mess with files or tricky steps. Everything synced up fast, so I could get back to working with my lists. If you want to keep your contacts in order and avoid hassle, this combo is a solid choice.
Everything is one place now with HubSpot
converting leads into email subscribers is a little tricky
