Running a Mailing List with Airtable, Twilio SendGrid and Python

A mailing list management system using Airtable, Twilio SendGrid, and Python is presented in this text. The system involves creating a new base and table in Airtable to store email addresses, setting up a form to collect emails from users, retrieving emails from Airtable using the Airtable API with Python, rendering markdown content for emails, and sending emails using Twilio SendGrid's API. A command-line interface (CLI) is also created to read a markdown file containing front matter with a subject variable. Best practices for email flow and legal requirements are discussed, and the source code is provided for reference.
