Frequently Asked Questions

Does Mailchimp integrate directly with HubSpot? ▼

Yes, Mailchimp has a native integration with HubSpot. It is available directly within the Mailchimp app marketplace.

Is the connection between Mailchimp and HubSpot secure? ▼

Yes. This integration typically uses OAuth 2.0, meaning you grant permission via a secure login window. You do not need to share your raw password, and you can revoke access at any time from your Mailchimp security settings.

Is the sync one-way or two-way? ▼

This is typically a one-way sync: Mailchimp → HubSpot. Changes in HubSpot do not sync back to Mailchimp.

Will existing data in Mailchimp sync to HubSpot? ▼

Usually, no. Most native integrations are "forward-looking," meaning they only sync data created or updated *after* you activate the connection. To move historical data, you will likely need to perform a one-time CSV export/import manually.
