Managing customer communication becomes easier when your marketing and CRM data work together. By connecting Mailchimp with Salesforce, businesses can keep their customer information aligned and make their outreach activities more organized. This is where Mailchimp integration helps create a connected workflow between both platforms.
To set up this connection, you need to generate Mailchimp credentials and configure the required authentication settings in MultiSync Made Easy. The steps below explain how to complete the setup using a Salesforce ETL tool and perform Mailchimp Salesforce integration for smooth data synchronization.
Step 1: Sign in to your Mailchimp account. If you don’t have an account, create one at mailchimp and complete the registration process.

Step 2: After signing in, you will see the Mailchimp dashboard. Click the Profile icon.

Step 3: Click Profile, then navigate to Extras.


Step 4: Under Extras, click Registered Apps. Fill in the required details. In Salesforce, copy the Callback URL displayed on the Mailchimp authentication page and paste it into the Redirect URL field in Mailchimp. Then click Create. Once the app is created, Mailchimp will generate the Client ID and Client Secret, which are required for authentication.


Step 5: Copy the generated Client ID and Client Secret from the Registered Apps page.

Now that you have generated the Client ID and Client Secret in Mailchimp, you can connect your Mailchimp account with MultiSync Made Easy. Follow the steps below to complete the authentication and start syncing your Mailchimp data with Salesforce.
Step 6: Log in to Salesforce. Open MultiSync Made Easy, click All, and search for Mailchimp.

Step 7: Select Mailchimp, enter the Client ID and Client Secret, and click Save & Authenticate. After that, the Mailchimp login page will appear. Enter your username and password, then click Log In. Next, click Allow to grant the required permissions.




Step 8: After granting permission, click Complete Authentication. Once the authentication is completed successfully, click Refresh. Now, click Import.



Step 9: On the Import page, click Proceed to continue.

Step 10: Click Preview Mapped Data to review the mapped records. Then click Validate Field Mapping to verify the mappings, and finally click Save Field Mapping to save the configuration.



Step 11: After saving the field mapping, click Sync Data to start syncing the data between Mailchimp and Salesforce.

Step 12: Once the synchronization is complete, the data from Mailchimp will be successfully synced with Salesforce through MultiSync Made Easy. The records will be created successfully, and the imported data will be available in Salesforce.

By following the above steps, you can generate the required Mailchimp credentials, complete the authentication process, and connect Mailchimp with MultiSync Made Easy. This setup allows you to sync data between Mailchimp and Salesforce in a simple and organized way.
