Let your agents read, send, and react to email autonomously

Hey HN, we're Haakam, Michael, and Adi. We're building AgentMail (https://agentmail.to/), an API to give AI agents their own email inboxes. We’re not talking about AI for your email, this is email for your AI. We started building email agents because they can converse with users in their inboxes, automate email-based workflows, and authenticate with third-party applications. Given these unique capabilities, we think email will be a core interface for agents. But we were building on top of Gmail, which was a struggle: poor API support, expensive subscriptions, rate limits,…

inbound ▲227Hey HN! I've been working on Inbound (inbound.new) - an email system that lets you programmatically manage email addresses and route them to AI agents, webhooks, or forward them anywhere. The core idea: instead of manually managing email addresses, you create them on-demand via API and route incoming emails to your AI agents or other automated systems. For AI Agents: Create [email protected] and emails get sent to your AI agent as webhooks. Your agent can reply using our SDK. Perfect for AI customer support or automated responses. For Email Forwarding: Set up [email protected] to…

Hi HN! We're Haakam, Michael, and Adi from AgentMail- a ycs25 company. We give AI agents their own email inboxes. Recently, we ran an experiment called Agent.Email. It's a signup flow designed specifically for AI agents instead of humans. The inspiration came from a few comments we received when we did our seed launch a few months back. They all came from the very apt observation that agents not being able to sign up to a product made for agents without human credentials was ironic and unideal. This is basically the thesis we built AgentMail on: The internet was made for humans exclusively,…

Hi HN! My co-founder and I spent the last 4 weeks building something we desperately needed ourselves. The Problem: We spend hours processing emails - scheduling meetings, going through long newsletters, downloading attachments to review, verifying documents like invoices, and of course taking actions on external systems (Salesforce, Asana, Jira etc) based on emails received. A lot of this can be automated with the help of AI agents, saving several hours every week. Our Solution: Forward any email to a specialized AI agent that completes the task and email you back the results. No…
