What are some alternative methods to sending out mass emails without using a third-party SaaS service?

The environmental impact of sending thousands of emails using a Python script and a spreadsheet template is minimal. Emails are a form of digital communication and do not directly contribute to physical waste or pollution. However, the servers that store and transmit emails do use electricity, which can have an environmental impact depending on the source of the electricity. But compared to physical mail, the impact is significantly less.

Global companies like Apple or Google can benefit from using a Python script to send out personalized emails in several ways. Firstly, it allows them to maintain the privacy and security of their email list, content, attachments, and credentials as the script runs directly on their personal computer. Secondly, it provides them with the flexibility to customize their emails according to the recipient, which can enhance the effectiveness of their communication. Lastly, it is a cost-effective solution as it is free of charge, unlike other email services online.
