About

OpenMail gives AI agents a dedicated email address. Provision an inbox with one CLI command or API call, each agent gets its own address, not a shared inbox or forwarding alias. Inbound email arrives instantly via webhook or WebSocket, parsed and threaded, with no polling required. Replies land in context so agents can respond without any new interface on the human side. Attachments: PDFs, CSVs, images, spreadsheets, Word documents are automatically converted to LLM-ready text; the agent never touches raw MIME. The API is small by design: one call to provision, standard calls to send, webhooks or WebSocket to receive. Integrates with LangChain, n8n, Make, Vercel AI SDK, and OpenClaw. Custom domains supported. Runs in the EU, GDPR-covered, 99.9% uptime SLA, SOC 2 in progress.

About

We are a team of engineers who love building tools for other engineers. Our goal is to create the email platform we've always wished we had — one that just works. Receive real-time notifications directly to your server. Every time an email is delivered, opened, bounces or a link is clicked. Simulate events and experiment with our API without the risk of accidentally sending real emails to real people.

Rely on a platform of reputable IPs used by trustworthy senders with distributed workloads across different IP pools. Get a fully managed dedicated IP that automatically warms up and autoscales based on your sending volume, with no waiting period.
