“Airbyte helped us accelerate our progress by years, compared to our competitors. We don’t need to worry about connectors and focus on creating value for our users instead of building infrastructure. That’s priceless. The time and energy saved allows us to disrupt and grow faster.”

"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 where you can view your subscriber list. Use the export feature to download your data in a CSV format. This can typically be done by selecting all subscribers and clicking on the "Export" button, which will generate a CSV file containing your data.
Open the exported CSV file in a spreadsheet editor like Microsoft Excel or Google Sheets. Ensure that the data fields are correctly labeled and organized, as this will facilitate the import process into MongoDB. You may need to clean up the data, removing any unnecessary columns or entries, and ensure that the data types (e.g., strings, numbers) are consistent.
MongoDB uses JSON-like documents for data storage, so you'll need to convert your CSV file into JSON format. You can use a script in Python or another programming language to accomplish this task. For example, using Python's `pandas` library, you can read the CSV and then use `to_json()` to convert it. Ensure that the JSON structure matches MongoDB's document model.
If you haven't already, set up a MongoDB database where you want to import the data. This involves starting a MongoDB server if you're running it locally or creating a cluster on a cloud service like MongoDB Atlas. Create a new database and collection within MongoDB where the converted JSON data will be stored.
Install MongoDB tools on your system if they aren't installed already. The MongoDB Database Tools package includes utilities like `mongoimport`, which allows you to import JSON data directly into your MongoDB collection. You can download the tools from the MongoDB website and follow their installation instructions.
Use the `mongoimport` utility to import your JSON file into the MongoDB collection you created. Open a command-line terminal and run a command similar to:
```
mongoimport --uri "mongodb://localhost:27017" --db yourDatabaseName --collection yourCollectionName --file yourFileName.json --jsonArray
```
Make sure to replace `yourDatabaseName`, `yourCollectionName`, and `yourFileName.json` with the appropriate names for your database, collection, and JSON file.
Once the import process is complete, verify that the data has been correctly imported into MongoDB. You can use the MongoDB shell or a GUI tool like MongoDB Compass to check the contents of your collection. Ensure that all fields are correctly mapped and the data appears as expected.
By following these steps, you can successfully transfer data from MailerLite to MongoDB without relying on third-party connectors or integrations.
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 is an intuitive email marketing solution for people of all skill levels. Simplicity is the core principle behind our solutions. We provide drag-and-drop content editors, simplified subscriber management, and advanced automation that are easy to set up.

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.
