Hey there👋,

2025 is quickly coming to an end, and we’ve got some exciting updates for you! We shipped AI tooling features (more on that below), we're hosting our first debate-style webinar, and we found ourselves genuinely excited about a data format called TOON. (We know, we know.)

Shipped

We made it easier for AI assistants to help you build with Postmark

Getting an AI assistant to help with your email integration shouldn't feel like explaining SMTP to your cat. We shipped three updates to fix that:

• An llms.txt file that gives AI tools accurate, structured information about our API and features (paste https://postmarkapp.com/llms.txt into ChatGPT or Claude when you need help).
• Pre-built AI prompts in our docs for common integration tasks like Node.js setup or password reset flows.
• A Model Context Protocol (MCP) server that lets AI assistants actually send emails and check stats through your Postmark account.

The result? Less time searching docs, fewer integration mistakes, and AI assistants that can actually help you ship faster. The MCP server is early access from Postmark Labs—we're actively looking for feedback on what to add next. Read more about our AI documentation tooling →

Webinar

Should developers use AI coding tools? Two perspectives, one honest conversation

The developer community is split on AI coding tools. Some see essential productivity boosters. Others see environmental disasters that plagiarize open-source work and erode fundamentals. Both sides have compelling points—and we're not picking a winner.

Join us December 3 at 2pm ET for a live, moderated debate between two experienced developers on opposite sides of this issue. No evangelizing, no dismissing concerns—just a structured exploration of the real trade-offs you face when deciding whether to use tools like GitHub Copilot, Cursor, or Claude Code.

Our latest, greatest finds from around the web

Here are three pieces that caught our attention this month - each tackling a different aspect of how developers and infrastructure are evolving:

TOON: Bye bye JSON for LLMs - Token-Oriented Object Notation cuts token usage by 30-60% compared to JSON when feeding structured data to LLMs. It's not meant to replace JSON everywhere, but for uniform tabular data passed to AI models, it's remarkably efficient.

The AI bubble is bigger than you think - This analysis examines the sketchy financial engineering underneath AI's infrastructure boom. Data centers financed through private credit, GPUs purchased with loans backed by other GPUs, and depreciation schedules that might not match reality.

Google Antigravity - Google's experimental agent-first IDE powered by Gemini 3. It's part of the broader shift toward AI-integrated development environments, alongside tools like Cursor 2.0. Worth exploring if you're curious about where coding environments are headed.
