Sending transactional emails via Firebase and Cloud Functions` In this tutorial, developers learn how to send transactional emails through Firebase using Google Cloud Functions. They start by setting up a simple Firebase database and use the real-time database trigger to fire off a transactional email via Postmark. The code is organized in a structured way, with a separate file for each Cloud Function. The `functions/db/users/onUpdate.f.js` file watches for new users and sends a welcome email using the nodemailer node module. The tutorial includes notes on how to handle errors and use environmental variables for sensitive data. The source code can be downloaded from this GitHub repo.

The upcoming Postmark iOS app is designed as a troubleshooting tool to help users quickly debug and resolve email issues on-the-go. The app offers features such as message search, inspection, bounce investigation, server stats monitoring, and account management. It aims to provide an optimized mobile experience for customers who need these tools, building upon the desktop version's success. Secure access is ensured through Touch ID or Face ID. The beta program allows Postmark users with admin or owner permissions to test the app and provide feedback.

Rebound for Postmark is a new integration that allows customers to be notified about email delivery issues from their web app, providing a more seamless experience. To get started, users need to sign up for a Postmark account and follow a step-by-step process to set up Rebound, which involves authorizing access to the Postmark account, choosing a server, editing notification appearance and messaging, and installing a custom JavaScript snippet near the closing `</body>` tag of their web app. The integration has some limitations, such as only triggering notifications for hard bounces and not spam complaints, but also offers flexibility through its callback function API. Users can provide feedback on Rebound to help improve future updates.
