On a late Friday evening, just when you’re about to call your day at the office, you receive an email stating a priority task. The Marketing Head has requested you to help him build an ETL pipeline for moving data from Mailchimp to Databricks. 

What would you do? You know that you can’t delay it because the end of the quarter is approaching, and the marketing team is working on tight deadlines for preparing the strategy of different email & ad campaigns.

Don’t worry; you’re in the right place. This article will give you the methods for building an ETL pipeline for replicating data from Mailchimp to Databricks. Enough talk! Let’s get to it.

How to Replicate Data From Mailchimp to Databricks?

To replicate data from Mailchimp to Databricks, you can either:

  • Use CSV files or 
  • A no-code automated solution. 

We’ll cover replication via CSV files next.

Replicate Data from Mailchimp to Databricks Using CSV Files

Mailchimp, being a Marketing Automation platform, helps you create, manage and analyze email and ad campaigns. It collects data on clicks, opens, social activity, purchases, and other interactions with customers.

Let’s dive into the process of replicating this data from Mailchimp to Databricks in CSV format:

Step 1: Export Data from Mailchimp

Here’s what you can export from your Mailchimp account: 

  • Audiences
  • Reports
  • Templates
  • Campaigns
  • Content studio files
  • Events

And here’s what you can’t export from your account:

  • Deleted audiences
  • Billing receipts
  • Third-party information
  • Website, landing page, and ad content

Let’s dive into the steps for exporting data from Mailchimp in CSV format.

  • Click your profile icon in the bottom-left corner.
  • Now, select the “Account” button.
  • Click the Settings drop-down menu. Now, select the “Manage my data” option.

  • Now, check the boxes for each type of data you want to export. Then, click on the “Export Data” button.

  • Your data will be bundled into a single ZIP file. You can download it from the “Manage my data” page.
  • You’ll also receive an email with the link after the download is ready. Click the link to go to the “Export My Data” page, and then click the “Download My Account Data” button.

NOTE: Keep the following points in mind while exporting data from Mailchimp.

  • You can do only one account export per 24-hour period.
  • You will receive an email from Mailchimp when your data export is ready. The export process might be time-consuming, especially if you have a large volume of data to export.
  • When the export is done, Mailchimp will create a ZIP file of all your requested data. This file is only accessible within your account and will not be included in the email you would receive from Mailchimp.

Step 2: Import CSV Files into Databricks

  • In the Databricks UI, go to the side navigation bar. Click on the “Data” option. 
  • Now, you need to click on the “Create Table” option.
  • Then drag the required CSV files to the drop zone. Otherwise, you can browse the files in your local system and then upload them.

Once the CSV files are uploaded, your file path will look like: /FileStore/tables/<fileName>-<integer>.<fileType>

If you click on the “Create Table with UI” button, then follow along:

  • Then select the cluster where you want to preview your table.
  • Click on the “Preview Article” button. Then, specify the table attributes such as table name, database name, file type, etc.
  • Then, select the “Create Table” button.
  • Now, the database schema and sample data will be displayed on the screen.

If you click on the “Create Table in Notebook” button, then follow along:

  • A Python notebook is created in the selected cluster.

  • You can edit the table attributes and format using the necessary Python code. You can refer to the below image for reference.

  • You can also run queries on SQL in the notebook to understand the data frame and its description.

In this case, the name of the table is “emp_csv.” However, in your case, we can keep it as according to your requirements.

  • Now, on top of the Pandas data frame, you need to create and save your table in the default database or any other database of your choice.

In the above table, “mytestdb” is a database where we intend to save our table. 

  • After you save the table, you can click on the “Data” button in the left navigation pane and check whether the table has been saved in the database of your choice.

Step 3: Modify & Access the Data

  • The data now gets uploaded to Databricks. You can access the data via the landing page’s Import & Explore Data section.

  • To modify the data, select a cluster and click on the “Preview Table” option.
  • Then, change the attributes accordingly and select the “Create Table” option.

With the above 3-step approach, you can easily replicate data from Mailchimp to Databricks using CSV files. This method performs exceptionally well in the following scenarios:

  • Low-frequency Data Replication: This method is appropriate when your product and marketing teams need the Mailchimp data only once in an extended period, i.e., monthly, quarterly, yearly, or just once. 
  • Dedicated Personnel: If your organization has dedicated people who have to select categories manually, customize templates, then download and upload CSV files, then accomplishing this task is not much of a headache.
  • Low Volume Data: It can be a tedious task to repeatedly select different categories, select templates or customize them, and download & upload CSV files. Moreover, merging these CSV files from multiple departments is time-consuming if you are trying to measure the business’s overall performance. Hence, this method is optimal for replicating only a few files.

When the frequency of replicating data from Mailchimp increases, this process becomes highly monotonous. It adds to your misery when you have to transform the raw data every single time. With the increase in data sources, you would have to spend a significant portion of your engineering bandwidth creating new data connectors. Just imagine — building custom connectors for each source, transforming & processing the data, tracking the data flow individually, and fixing issues. Doesn’t it sound exhausting?

Instead, you should be focussing on more productive tasks. Being relegated to the role of a ‘Big Data Plumber‘ that spends their time mostly repairing and creating the data pipeline might not be the best use of your time.

To start reclaiming your valuable time, you can…

Replicate Data from Mailchimp to Databricks Using an Automated ETL Tool

Going all the way to write custom scripts for every new data connector request is not the most efficient and economical solution. Frequent breakages, pipeline errors, and lack of data flow monitoring make scaling such a system a nightmare.

Summing It Up

Exporting and importing CSV files would be the smoothest process when your marketing team requires data from Salesforce only once in a while. But what if the marketing team requests data from multiple sources at a high frequency? Would you carry on with this method of manually importing & exporting CSV files from every other source? In this situation, wouldn’t you rather focus on something more productive? You can stop spending so much time being a ‘Big Data Plumber’ by using a custom ETL solution instead.

A custom ETL solution becomes necessary for real-time data demands such as monitoring email campaign performance or viewing the sales funnel.
