How to export contacts from Mailchimp

Mailchimp exports an audience as CSV, usually a ZIP with one CSV per contact status, and emails you when it's ready. It has no Excel export, so to get a spreadsheet you open the CSV in Excel or Google Sheets.

  1. Click Audience, and choose the audience from the dropdown if you have more than one.
  2. Click Export audience, then Export CSV.
  3. Wait for the email saying the export is ready, then download the file from the link in it.
  4. If it's a ZIP, unzip it. There's one CSV per contact status: subscribed, unsubscribed, non-subscribed and cleaned.

To export only some contacts: for a saved segment, choose it from the Segments dropdown and click Export segment. For a tag, choose it from the Tags dropdown, then click Save as segment and Export CSV.

Only Owners and Admins on the Mailchimp account can export an audience.

For a CRM import, use the subscribed file. Keep the unsubscribed and cleaned files out of your CRM, or add them to a suppression list so those contacts are never emailed again.

To get it into Excel, use Data > From Text/CSV rather than double-clicking the file: it keeps accented names intact, and choosing Transform Data lets you set the Zip column to text so leading zeros stay. Then save as an Excel workbook. In Google Sheets, use File > Import and upload the CSV.

Where Mailchimp and HubSpot don’t line up

Three columns kept in Notes

This template gives MEMBER_RATING, OPTIN_TIME and TAGS no HubSpot field of their own. A HubSpot contact has no Notes field: imported with contacts and notes together, the text becomes a note on the contact.

The template writes them into Notes, each with its label, and leaves empty ones out.

Questions

Where does Mailchimp's export fill Email, which HubSpot requires?

Email comes from Mailchimp's Email Address column, lowercased. The checker above counts the rows with Email blank.

Where do MEMBER_RATING, OPTIN_TIME and TAGS go?

Into one note on each contact, labeled like "Mailchimp rating: 4 | Opted in: 2026-03-02 10:41:07 | Tags: "Webinar", "Newsletter"". Importing the same contacts again adds a second note.

What happens to unsubscribed contacts?

Mailchimp includes unsubscribed contacts in the export with a status column. This template maps the contact fields but does not set email opt-out status in HubSpot. Check the subscription status column and update HubSpot opt-in settings separately.
