"With Airbyte, we could just push a few buttons, allow API access, and bring all the data into Google BigQuery. By blending all the different marketing data sources, we can gain valuable insights."
Begin by logging into your MailerLite account. Navigate to the 'Subscribers' section and select the group you want to export data from. Click on the 'Export' button and choose the desired format, typically CSV or Excel. This will download your subscriber data to your local machine.
Open the exported file using a spreadsheet application like Microsoft Excel or Google Sheets. Review the data to ensure that it includes all necessary fields and is formatted correctly. Make sure there are no special characters or formatting issues, which might cause errors during the import process.
Log into your Oracle Database using SQLPlus, SQL Developer, or another Oracle client tool. Ensure you have the necessary permissions to create tables and insert data. If needed, contact your database administrator to verify your access rights.
Write and execute a SQL script to create a table in Oracle that matches the structure of your MailerLite data. Define columns with appropriate data types (e.g., VARCHAR2, NUMBER, DATE) that correspond to the fields in your exported file. For example:
```sql
CREATE TABLE mailerlite_data (
subscriber_id NUMBER,
email VARCHAR2(100),
name VARCHAR2(100),
signup_date DATE
);
```
Use a script or tool to convert your CSV data into SQL INSERT statements. This can be done manually or by using a simple script in a language like Python, which reads the CSV file and generates SQL statements for each row. Ensure the values are properly formatted for SQL (e.g., strings are enclosed in single quotes).
Open your Oracle client and execute the SQL INSERT statements generated in the previous step. This can be done by pasting the statements directly into your SQL tool or running a script if the file is large. Monitor the process for any errors, and address them as needed.
Once the data import is complete, run a few SQL queries to verify that the data in Oracle matches your MailerLite records. Check for the correct number of rows and validate a few sample entries to ensure accuracy. If discrepancies are found, correct them by updating the data directly in Oracle.
By following these steps, you can successfully transfer your data from MailerLite to Oracle without relying on third-party solutions.
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.

MailerLite'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 MailerLite's API:
1. Subscribers: This category includes data related to subscribers such as their email address, name, location, and subscription status.
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.
