Begin by logging into your Mailchimp account. Navigate to the "Audience" section and select the list you want to export. Click on "Manage Audience" and choose "Export Audience." This will generate a CSV file containing your audience data. Download this CSV file to your local machine.
Open the downloaded CSV file using a spreadsheet application like Excel or a text editor. Review the data to ensure it is clean and well-structured, as Elasticsearch requires JSON format for data ingestion. Convert the data into a JSON format, ensuring each record is properly structured as a JSON object. Save this file with a .json extension.
If you haven't already, set up an Elasticsearch instance. You can do this by downloading Elasticsearch from the official website and following the installation instructions for your operating system. Once installed, start the Elasticsearch service and ensure it is running by accessing the Elasticsearch API endpoint at `http://localhost:9200`.
Before importing data, create an index in Elasticsearch that will store your Mailchimp data. Use the Elasticsearch API to create an index by sending a PUT request to `http://localhost:9200/{index_name}`, where `{index_name}` is your desired index name. Customize the index settings and mappings as needed to match the structure of your JSON data.
cURL is a command-line tool for transferring data using various protocols and is essential for sending data to Elasticsearch. Ensure cURL is installed on your system. On Linux, it is usually pre-installed. On Windows, download it from the official cURL website. Verify the installation by running `curl --version` in your terminal.
Use cURL to import the JSON data into your Elasticsearch index. Open a terminal and execute a POST request with cURL, specifying the JSON file and the Elasticsearch index URL. The command should look like this:
```
curl -X POST "http://localhost:9200/{index_name}/_bulk" -H "Content-Type: application/json" --data-binary "@yourfile.json"
```
This command uploads the JSON data to the specified index. Ensure the JSON file is formatted correctly for Elasticsearch’s bulk API.
After the data import, verify that the data has been correctly transferred to Elasticsearch. Use the Elasticsearch API to query the index and check the data. You can run a GET request such as:
```
curl -X GET "http://localhost:9200/{index_name}/_search?pretty"
```
This will return the data stored in the index in a readable format. Review the output to confirm that all records are present and correctly structured.
FAQs
What is ETL?
ETL, an acronym for Extract, Transform, Load, is a vital data integration process. It involves extracting data from diverse sources, transforming it into a usable format, and loading it into a database, data warehouse or data lake. This process enables meaningful data analysis, enhancing business intelligence.
Mailchimp is a global marketing automation platform aimed at small to medium-sized businesses. Mailchimp provides essential marketing tools for growing a successful business, enabling businesses to automate messages and send marketing emails, create targeted business campaigns, expedite analytics and reporting, and effectively and efficiently sell online.
Mailchimp's API provides access to a wide range of data related to email marketing campaigns. The following are the categories of data that can be accessed through Mailchimp's API:
1. Lists: Information about the email lists, including the number of subscribers, the date of creation, and the list name.
2. Campaigns: Data related to email campaigns, including the campaign name, the number of recipients, the open rate, click-through rate, and bounce rate.
3. Subscribers: Information about the subscribers, including their email address, name, location, and subscription status.
4. Reports: Detailed reports on the performance of email campaigns, including open rates, click-through rates, and bounce rates.
5. Templates: Access to email templates that can be used to create new campaigns.

7. Tags: Information about tags that can be used to categorize subscribers and campaigns.
Overall, Mailchimp's API provides a comprehensive set of data that can be used to analyze and optimize email marketing campaigns.
What is ELT?
ELT, standing for Extract, Load, Transform, is a modern take on the traditional ETL data integration process. In ELT, data is first extracted from various sources, loaded directly into a data warehouse, and then transformed. This approach enhances data processing speed, analytical flexibility and autonomy.
Difference between ETL and ELT?
ETL and ELT are critical data integration strategies with key differences. ETL (Extract, Transform, Load) transforms data before loading, ideal for structured data. In contrast, ELT (Extract, Load, Transform) loads data before transformation, perfect for processing large, diverse data sets in modern data warehouses. ELT is becoming the new standard as it offers a lot more flexibility and autonomy to data analysts.
