Want agents to use your product? Ask yourself: 1. Can an agent sign up? @agentmail gives agents email inboxes they can use during signup. 2. Can it try enough of your product? Your free plan should include enough credits to finish a useful task, so the agent can evaluate your product before paying. 3. Does the whole workflow work? Start with a fresh account and follow your public quickstart. Run the exact code snippets and check that they produce the expected result before the free credits run out. I represented The Prompting Company (@promptingco) on this panel with @RushShahani, @kaushik_himself and Weiguang Shi, sharing what it takes for agents to actually use a product.

AgentArmor is now live. We’ve seen a lot of success with our beta test users and are excited it is now GA, Go check it out in the console! console.agentmail.to
Today, we’re introducing AgentArmor. Email is one of the largest attack surfaces for agents, making them susceptible to prompt injection attacks through untrusted inbound messages. We trained a specialized model to detect malicious emails for our users - having helped prevent hijacking workflows, extracting sensitive bank data, and triggering unauthorized actions for our early beta test users. Excited for everyone to try it!

Claude came last in our AI agent evals. Here's why: it found the emails fine, but wouldn't reply to anything flagged as spam, even when told to. Bug or the safest default? Read on to learn more

October’s on pace to be our biggest month yet.. by a country mile. There is really no upper bound in startups. It catches you time and time again.

Agents can sign in. Now they're buying. Oct 27 I'm doing a fireside with @promptingco at @WorkOS SF on how agents pick tools and what it takes to build for them. Exa and Browserbase are talking too. RSVP below 👇

Check us out (again) at agentmail.to
Today, @agentmail has processed over 1 Billion emails. A year ago, we processed under 20 million. So we figured it was time for AgentMail to grow up a little too :)

Each agent will need its own search API key to get personalized results. Excited to work with @agentmail on this. Two agents search “Andrey Styskin biography”. HR wants artifacts: projects I’ve built, articles I’ve written. Sales wants common ground: past companies, communities, shared connections. With separate IDs, @KeenableAI will learn from the results each agent looks and personalize retrieval and ranking. We’re building the whole search stack to connect each agent with the knowledge it actually needs.
