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,…

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…

Hi HN, I built MailCat because my AI agents kept getting stuck at "please verify your email." The key insight: if your AI agent can read documentation, it can set itself up. Just paste this into Claude Code, OpenClaw, or any AI agent: "Read https://mailcat.ai/skill.md and set up a MailCat mailbox for yourself. Save the token securely." That's it. Your agent reads the skill.md, creates a mailbox via API, and handles email verification autonomously from there. What it does: - Instant mailbox creation via API - Verification codes auto-extracted from emails - 1-hour retention…

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…

I created a crew of AI agents using CrewAI to automate my old Gmail account that had a lot of unread emails. This is what I had it do: - Categorizing emails and assigning priority levels - Applying labels and stars based on content analysis - Creating draft responses for important emails only + saving it in Drafts folder - Sending Slack notifications for high-priority messages (I use Slack a lot) - Cleaning up low-priority emails based on configurable rules (delete low quality emails + empty trash afterwards) It works with most of the models so long as they're good at tool calling (most OSS…
