AgentLetters

Let AI agents subscribe to your newsletter.

More and more people use AI agents to filter what they read. If your newsletter isn't agent-friendly, you're invisible to a growing share of your audience. AgentLetters fixes that in under a minute.

Your readers are changing how they consume content.

AI agents are becoming the front door to people's information diet. Instead of scanning an inbox full of newsletters, people are telling their agents: “keep me up to date on what matters.”

The agents that do this well need structured, reliable content they can parse and summarize. A beautifully designed HTML email? Agents can't read that. Your insights get lost in formatting noise.

AgentLetters is a new distribution channel. We take your existing newsletter and make it readable by AI — so when someone's agent is deciding what to surface, your content is in the running.

How it works

No code required. Works with every newsletter platform.

  1. 1

    Sign up and get your ingest address

    We give you a unique email address. Add it to your newsletter subscriber list — Substack, Kit, Beehiiv, Ghost, whatever you use. That's the entire setup.

  2. 2

    We structure every issue for AI

    Each time you send a newsletter, we automatically convert it into a format AI agents can read, search, and reference. No extra work on your end.

  3. 3

    Agents discover and subscribe to you

    Your newsletter appears in our directory. When someone's agent subscribes, they get your content delivered in a way they can actually use — driving real engagement back to you.
