The best practice of the MailJet class library in large -scale emails

Mailjet is a popular email service provider. It provides a powerful -functional library to simplify large -scale mail sending in Python.The following is the best practice when using the Mailjet class library for large -scale mail. 1. Import the Mailjet class library: First of all, you need to import the Mailjet class library in the code.You can use the `pip` command for installation, and then use the` Import` statement to import the MailJet class library. python from mailjet import Client 2. Create the Mailjet client: Next, you need to use the API key to initialize the Mailjet client.Create an account on the Mailjet website and get the API key.The constructor that passes the API key to the Mailjet client. python api_key = 'your-api-key' api_secret = 'your-api-secret' mailjet = Client(auth=(api_key, api_secret)) 3.
