One Inbox to Rule Them All: My Personalized Newsletter Digest App - Powered by Postmark

✨ The Problem

Let’s face it — newsletters are amazing... until they aren’t.

Between tech updates, founder essays, product launches, and weekly deep-dives, we subscribe to way too many. The result? Inbox chaos. Important insights get buried, and we spend more time filtering than reading.

💡 The Idea

So I built a solution:

Here You can Try

An app that turns N newsletters into ONE personalized daily/weekly digest — powered by Postmark.

The goal? Cut the noise. Keep the value.


🛠️ How It Works

  1. Smart Parsing: Newsletters are forwarded to a unique address.
  2. AI Summarization: Each email is scanned, summarized, and categorized.
  3. Personal Preferences: You pick the topics you care about.
  4. Digest Delivery: Postmark reliably delivers your single, clean, beautifully formatted digest.

🚀 Why Postmark?

Email deliverability makes or breaks this kind of app.

Postmark’s lightning-fast, developer-friendly platform ensured:

  • ⚡ Instant, reliable delivery of digests
  • 💌 Beautiful, templated emails with Markdown support
  • 📈 Analytics for open/click rates so users stay informed

I have used the postmarks custom inbound domain forwarding feature to generate n numbers of mail ids for my users.

Custom Domain

The process was very simple and easy to implement as every step is properly documented by postmark team in their dev docs.

📬 Why It Matters

This app isn’t just about saving time. It’s about reclaiming attention.

We’re drowning in content — not because we’re reading too much, but because we’re managing too many channels. A personalized digest brings back focus.


🔮 What’s Next?

  • 🔗 Integrations with Gmail/Outlook

💬 Final Thoughts
