First, ensure you have SMTP access to your Mailjet account. Log in to your Mailjet dashboard, navigate to the SMTP settings, and note down the SMTP server address, port, and your Mailjet account credentials. This information will be used to connect to your Mailjet account programmatically.

Use Python’s built-in `smtplib` library to connect to the Mailjet SMTP server. This involves writing a Python script that connects to the SMTP server using the credentials you obtained in the previous step. This script will allow you to send commands to the server and retrieve email data.

Once emails are retrieved, use Python’s `email` library to parse the email content. This library allows you to work with the MIME structure of the email and extract essential components such as the subject, sender, recipient, and body of the email.

Install Redis on your local machine or server where you plan to store the email data. You can download it from the official Redis website and follow the installation instructions for your operating system. Start the Redis server to prepare it for data storage.

Install a Python client for Redis, such as `redis-py`, using pip. This library will enable your Python script to interact with the Redis database. Use the command `pip install redis` to install it.

Modify your Python script to store the parsed email data into Redis. Use the `redis-py` library to connect to your Redis server and store each email's data as a Redis key-value pair. For instance, you can store each email with a unique ID as the key and a JSON object containing the email details as the value.

Finally, verify that your email data has been correctly stored in Redis. You can use the Redis CLI or a GUI tool like RedisInsight to query your Redis database and check the stored data. Ensure the data is stored in the expected format and retrievable as needed.

This guide provides a direct approach to moving email data from Mailjet to Redis using Python, without relying on third-party connectors or integrations.
