Using Cloud Functions triggered by a create event in Firestore allows you to easily integrate email notifications with your ecommerce order processing flow. When a new order is created and stored in Firestore, the Cloud Function is automatically invoked. Within the function, you can implement the logic to send a customized email (using an email provider like SendGrid, Mailgun, etc.). This approach minimizes deployment effort and management overhead because Cloud Functions are fully managed and event-driven. Option A is the most streamlined solution compared to running a Compute Engine instance (Option B), setting up alerting based on logs (Option C), or using Pub/Sub based solely on an HTTP response (Option D), which aren’t as well-suited for sending custom, timely customer emails.
