Begin by logging into your MailerLite account and navigating to the data export section. Typically, you'll want to export your subscriber list or campaign data. Choose the appropriate data set and export it in a CSV format, as this is widely supported and easy to manipulate.
Open the exported CSV file using any spreadsheet application or a text editor. Review the data to ensure it includes all the necessary fields you plan to import into Elasticsearch. Consider converting the CSV into a JSON format, as Elasticsearch operates efficiently with JSON. Use scripts or tools like Python's `pandas` library to transform the CSV into JSON documents.
Ensure you have an Elasticsearch instance running. You can either set up a local instance or use a cloud service like Elastic Cloud. Configure your instance according to your data requirements, including defining the index where you intend to import the data. An index is similar to a database in traditional SQL systems.
Before importing data, it's essential to define a mapping for your Elasticsearch index. This mapping specifies the data types and structures for each field in your documents. Use the Elasticsearch API to create this mapping, ensuring that it aligns with the structure of your JSON documents.
Develop a script to automate the data import process. You can use Python with the `elasticsearch-py` library to create a script that reads your JSON file and sends bulk requests to Elasticsearch. Ensure your script handles errors and retries failed requests to guarantee a complete data import.
Run your script to start importing data into Elasticsearch. Monitor the process to ensure that all documents are correctly indexed, and watch for any errors that might occur. This step will populate your Elasticsearch index with data from MailerLite, making it searchable and ready for analysis.
After the import process is complete, verify the data integrity in Elasticsearch. Use the Kibana interface or Elasticsearch API to query your index and confirm that the data matches the original dataset from MailerLite. Check for any discrepancies or missing data and re-import if necessary.
By following these steps, you will successfully transfer data from MailerLite to Elasticsearch without using third-party connectors or integrations, ensuring you have complete control over the process.
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.

2. Campaigns: This category includes data related to email campaigns such as the subject line, content, delivery time, and open and click-through rates.
3. Lists: This category includes data related to email lists such as the name of the list, the number of subscribers, and the date the list was created.
4. Segments: This category includes data related to segments such as the name of the segment, the criteria used to create the segment, and the number of subscribers in the segment.
5. Automation: This category includes data related to automated email campaigns such as the trigger, content, and delivery time.
6. Forms: This category includes data related to forms such as the name of the form, the number of submissions, and the date the form was created.
7. Reports: This category includes data related to email campaign reports such as the number of opens, clicks, bounces, and unsubscribes.
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.
