​
Overview

Traza uses email notifications to keep users informed about important events and updates in the platform. We use Mailgun as our email service provider to handle all email communications.

​
Technical Implementation

​
Email Provider

We use Mailgun for sending all our email notifications. The configuration is managed through Firebase Cloud Functions config: 
const API_KEY = functions.config().mailgun?.api_key;
const DOMAIN = functions.config().mailgun?.domain;

​
Trigger Mechanism

Email notifications are triggered through Firebase Cloud Functions that listen to specific Firestore document changes. When certain events occur (like creating a booking), the corresponding Cloud Function is triggered, which then processes the event and sends the appropriate email notification. Example trigger structure: 
export const onEventTrigger = functions
  .region("australia-southeast1")
  .firestore.document("collection/{documentId}")
  .onCreate((snap, context) => {
    // Process event and send email
  });

​
Current Email Notifications

​
1. New Booking Request

  • Trigger: When a new booking is created in Firestore
  • Recipient: Tattoo Artist
  • Content:
    • Artist receives details about the new booking request
    • Includes customer name, preferred dates, time of day, and service type
  • Opt-out: Not available (critical notification)

​
Future Considerations

  1. Email Template System
    • Consider implementing a templating system for consistent email styling
    • Make email templates easier to maintain and update
  2. Email Preferences
    • Implement an email preference center for users
    • Allow users to customize which non-critical notifications they receive
  3. Analytics
    • Track email delivery rates
    • Monitor email engagement metrics
