What are some alternative methods to send thousands of personalized emails apart from using this Python script?

While it might seem that sending emails is environmentally friendly, it does have a carbon footprint. This is because data storage, servers, and the energy used to send emails all contribute to CO2 emissions. However, the impact is significantly less than traditional mail. The exact environmental impact can vary greatly depending on the energy efficiency of the data centers involved.

Global companies like Apple and Google can utilize this Python script to send personalized emails to their customers by integrating it into their existing customer relationship management systems. They can use the script to automate the process of sending out personalized emails based on customer data stored in their databases. This can include promotional emails, updates, or even responses to customer inquiries. The script can be customized to include attachments and signatures, and can start sending emails from any row in the database, providing flexibility in how the emails are sent out.
