A mailing list can be a great way to share information with a group of people. Google Forms provides the tools needed to handle subscriptions to a mailing list, and this tutorial will build a Google Form that is backed by a Google Spreadsheet. The spreadsheet will be used as a storage mechanism for a list of subscribers. Then we will create a Python script that reads the spreadsheet and finally we will use the Twilio SendGrid Python client to send emails to all subscribers.
