LobsterMail: Email infrastructure for AI agents

Hey Product Hunt — @Sam here from Lobstermail. We built LobsterMail because we kept running into the same problem while building AI agents for our main startup (Palisade - email deliverability): giving an agent email was painful. Your personal inbox is a no-go. Gmail requires a ton of human setup. And every other solution still needs a human to sign up on behalf of the agent. We wanted something agent-first — where the agent handles the entire signup flow on its own. One API call, own @lobstermail.ai address, sends and receives immediately. A few things we're proud of under the hood: Every inbound email gets scanned for prompt injection before it reaches the agent's context. Email is an open attack vector that most people don't think about until it's too late. Each agent gets isolated sending reputation via separate SES config sets. One bad actor can't tank deliverability for everyone else. The entire flow is API-only — no dashboard to configure, no OAuth to fight. Agents don't use dashboards. Happy to answer any questions about the architecture here. The deliverability side was the hardest part by far. Free to receive and send. $9/mo for Builder account. We're running a 3-month free Builder tier for early users. lobstermail.ai
