Import Contacts to Mailchimp

Our import tool helps you add or update email contacts in Mailchimp. Import from a connected app, upload a comma-separated value file (CSV), copy and paste email contacts from a spreadsheet like Microsoft Excel or Google Sheets, or enter info directly into the import table. You can also auto-update multiple existing email contacts at once.

In this article, you'll learn how to use our import tool to add and update email contacts in Mailchimp.

Before you start

Here are some things to know before you begin this process.

• This article covers how to import email contacts to your Mailchimp audience. To learn how to import SMS contacts to your Mailchimp audience, check out Import SMS Marketing Contacts to Mailchimp.
• Free plans include up to 500 contacts and 1,000 email sends per month, with a daily email send limit of 500. To learn more, check out our pricing page.
• If your import brings your total contact count above the limit of your marketing plan tier, you'll be subject to additional charges.
• Some European spreadsheet programs use semicolons to separate data fields in CSV or TXT files. If your import file uses semicolons, replace them with commas and try your import again. To learn more, check out Troubleshooting Contact Imports.
• In Mailchimp, you can categorize your email contacts based on their email marketing status, such as subscribed or unsubscribed. You can only import 1 status at a time.

Import email contacts from another service

To save time and effort, Mailchimp lets you connect 6 of the most commonly used integrations and will import email contacts for you. Here’s the list of currently supported apps:

3. Click the Manage Audience drop-down and choose Import contacts.

5. Click Continue.
6. Click Add on the integration tile you want to work with. Previously connected integrations will have a checkmark.
7. After you’ve connected the app, click Done.

That’s it! You’ve now connected your app and Mailchimp will import email contacts.

Import email contacts from a file

The file import process has 2 parts. First, prepare your spreadsheet of email contacts outside Mailchimp, then save it as a CSV or TXT file. Next, use our import tool to upload your file and add your email contacts to your Mailchimp audience. If you import subscribed email contacts, be sure that you have permission to send them email marketing content.

Prepare for import

To prepare your file for import, follow these steps.

1. In a spreadsheet program like Microsoft Excel or Google Sheets, open your blank worksheet.
2. Create and label a column for Email Address. This field is required to import email contacts.
   
3. Create and label additional columns for First Name, Last Name, and any other information you want to import to Mailchimp.
   
   To learn how to format phone numbers, birthdays, mailing addresses, and other types of data, check out Format Guidelines for Your Import File.
4. Add your contacts' information into the relevant fields in the spreadsheet.
   
5. Save the file in a CSV or TXT format. These options can usually be accessed from the File menu in your spreadsheet program, labeled as "Export as .CSV,” “Export as .TXT,” “Download as .CSV,” or “Download as .TXT.” Spreadsheet programs may vary.

Nice job! Now that you've prepared your import file, you're ready to import.

• Subscribed email contacts being imported into Mailchimp don't go through the signup process. You’ll need to verify that you have permission to market to them.
• When you import email contacts to an existing audience, we won’t include any duplicate, bounced, or unsubscribed addresses that are already stored in the audience.
• Because all audiences in Mailchimp are independent of each other, we can't detect duplicates, bounces, or unsubscribes across multiple audiences. If you have duplicate email contacts in different audiences, you may find it helpful to combine your audiences into a primary audience that uses groups or tags.

Update existing email contacts

You may need to update your email contacts’ data if they’ve been in your audience for a while. Use our import tool to quickly update multiple contacts at once.

This option replaces existing audience field information with new information from your import file. You’ll follow the same process to import new email contacts, but there are a few extra things to consider.

• When you prepare your spreadsheet, verify that the column names in your import file match the fields in your Mailchimp audience, and that no columns are left blank. Blank fields overwrite and erase existing email contact data.
• You can only update subscribed or non-subscribed email contacts with this method.
• Imports won’t update the marketing status of email contacts already in your Mailchimp account.

After your import file is prepared with updated contact information, follow the same steps to import email contacts from a file. On the Organize step, check the box next to Update any existing contacts.

That's it! When you import, we'll handle the rest by scanning your email contacts and updating their information.
