AgentMailr – dedicated email inboxes for AI agents
I kept running into the same problem while building AI agents: every agent that needs email ends up sharing my personal inbox or a single company domain. That breaks attribution, creates deliverability risk, and makes it impossible to test sender identities per agent. So I built AgentMailr. You call an API to create an inbox, your agent gets a unique email address, and replies route back to that specific agent. Works for both inbound (OTP parsing, reply routing) and outbound (cold email, notifications). Bring your own domain is supported so emails come from your domain, not ours. REST API…

What it does
The action layer for AI agents: a real email inbox, OTP and login automation, a stealth browser, and an encrypted credential vault, all from one API.
Email, logins, meetings, and a credential vault. The real-world primitives your AI agent needs to sign up, get in, and act on its own. # RECEIVED_MAIL_0822 { "id" : "lum_8x2..." , "from" : "[email protected]" , "parsed_data" : { "category" : "SECURITY" , "otp" : "882-941" , "action" : "VERIFY" } } Deploy Now Documentation Protocol 01 // Identity Stack The Login Stack. One API. Inbox, stealth browser, and credential vault. Every piece your agent needs to sign up, get the OTP, log in, and stay logged in. One key, one bill, one runtime. POST /v1/skills/signup_with_email { "url": "https://app.x.com/signup", "inbox": "github-bot" } → { "inbox": "[email protected]", "otp": "847291", "session":…from agentmailr.com

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,…

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,…

inbound 2025 · inbound.new · ▲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…
