Mailchimp Database Integration Guide: How to Connect Any App to Mailchimp

Marketing in the digital realm is highly regarded as a powerful way to expand a business’s clientele. Many Mailchimp users extend its functionality by integrating their favorite apps or platforms with Mailchimp database to allow them to reach more people and increase their revenue.

Are you a new or regular user of Mailchimp who needs to integrate it with your other applications and databases? Follow this article to learn more about the various techniques for integrating apps with Mailchimp.

The basics of Mailchimp integration with database

Mailchimp is a centralized hub that enables you to better manage your customer base. However, its potential is almost limitless when combined with other apps, databases, and data warehouses. 

Mailchimp database integration allows for bidirectional data flow between two platforms. This data may later be utilized to develop useful analytics and insights, spike up sales, create targeted email campaigns, etc.

Next, we’ll talk about the requirements, types of integrations, and the various examples of databases one can connect Mailchimp to.

Mailchimp database integration requirements

You need to make certain that the following prerequisites are met before you can go on with setting up the Mailchimp database integration:


  • A user account with Mailchimp 
  • Concise understanding of what data is to be transferred.

For integrating Mailchimp and databases or data warehouses:

  • Familiarity with databases and data warehouses such as MongoDB, MySQL, BigQuery, etc.

For applications:

  • An active account with the desired application, with a relevant subscription if necessary for integrating with Mailchimp

Benefits of Mailchimp database management 

Collecting and analyzing client information is essential for effective marketing. By managing your Mailchimp database, you’ll start to:

  • Expand your client base by mining your data.
  • Learn new approaches to communicating with others who share your interests and values.
  • Put the appropriate information in front of the relevant individuals.
  • Consider your target market more closely.  

Mailchimp database structure

The following are the primary components that make up the Mailchimp database structure.

  • Audience: Mailchimp audience can help you keep track of who has subscribed, who hasn’t, and who has unsubscribed. Your Mailchimp audience is much more than your email address; it is where you keep all of your contact information. With audience, you can learn everything there is to know about the customers who keep your business thriving.
  • Record: A record is a compilation of information pertaining to a certain member of your audience. The contact’s email address is used as the record’s unique identifier while working within Mailchimp. Mailchimp bills you for the number of records your account possesses.
  • Field: Fields are containers in which you can store certain information that is uniquely associated with a given record. This is where the most vital information about a person is stored, which may include the individual’s name, email address, date of birth, and other details. The values contained in fields could either be alphanumeric or numeric.
  • Segment: Segments are used to classify subscribers in order to make it possible to form targeted groups by utilizing the subscribers’ own data. When you build a segment, you’ll specify rules to filter contacts based on the information that is accessible in your audience. 
  • Group: Groups are organized collections of contacts that are arranged according to the users’ preferences or interests. Through the use of groups, you are able to collect information about your contacts’ preferred foods, retail locations, or anything else of interest to you.
  • Tag: Tags allow you to label, or otherwise classify, contacts in accordance with the information you have about those contacts. Using tags is a great way to keep your contacts organized. You can modify your tags and use them in any way that you see fit.

Mailchimp database sync 

Mailchimp integration with database and other platforms allows for seamless data transfer. Mailchimp database sync allows for data consistency and the following listed below can be linked when setting up your Mailchimp integration:

  • E-commerce data: By linking your online shop to Mailchimp, for example, your Shopify online store, you can send specific information to your customers. This information could be order confirmations, reminders about abandoned purchases, and coupons for products they were considering but ultimately did not buy, etc.
  • Customer data: Followers, subscribers, contacts, and customer data may be added to Mailchimp database as audience instantaneously through integrations with apps like Pipedrive, Zendesk, etc. Whenever you make changes to your Mailchimp data and send it to your customers, the changes will be reflected in your external app, and vice versa.
  • Website pop-up forms: To better communicate with site visitors, you may use a pop-up form that you can customize in Mailchimp. Google remarketing advertisements through Mailchimp are another way to get the attention of visitors who have already visited your website or landing page.
  • Events: Events are unique data points that may be used to learn more about your customers’ habits and build targeted audiences. Some integrations sync the events you control with an external app, for example, Google Analytics, Facebook, etc., with your Mailchimp account. New events will continue to sync independently until you disable the integration.
  • Tags: You may find it much easier to manage your contacts if they are tagged. Your contact may be associated or identified with the app from which it was synced to assist you in figuring out what the data is all about and where it originated from.

Mailchimp SQL database integration

You can connect your Mailchimp database to different SQL databases and data warehouses like MySQL, MSSQL, BigQuery, OracleDB, etc. For Mailchimp to link to your database, you’ll need to access the required data using the REST API that Mailchimp provides. The API offers users many interaction endpoints, for example, lists, campaigns, etc. The returned Mailchimp data is in JSON format. You can interact directly with the API or use a tool like a curl.

If you’re a BigQuery user, you can use a no-code tool like to automate linking Mailchimp to your database. We’ll share an example in the following chapter.

But first, let’s look at the following code snippet, which shows how to access the Mailchimp API using the curl command to load data from Mailchimp to the MySQL server. 

curl --request GET
--url '' --user 'anystring:apikey' --include

The response will be similar to the following:

 "lists": [
     "id": "278g465nb77",
     "name": "Favour's Notes",
     "contact": {
       "company": "MailChimp",

       "state": "New York",
       "zip": "10001",
       "country": "US",
       "phone": ""

You will need a schema to load the Mailchimp JSON response into your data tables. Most importantly, you need to check that the data types in the Mailchimp file correspond to the data types in your SQL database.

By typing the following command into the MySQL Shell, you can import your Mailchimp JSON document all at once.

$ mysqlsh root@localhost:3000/<schema> --import /path_to_file/<file_name>.json
