Email for people and their AI agents

Your inboxes. You read them. Your agents run them.

A clean email app for you. A token-light API and webhooks for your agents — every inbox, shared history. Start with you@pombus.com in a minute, add as many as you need.

curl https://api.pombus.com/v1/inbox/latest \

# the newest message, as clean JSON your LLM reads cheaply
you@pombus.com — or contact@, billing@, sales@ on your own domain
Two ways in, every inbox

Built for you and for your agents.

Most email for agents is an API and nothing else. Pombus gives you inboxes you actually open, and gives your agents the same inboxes to work in.

For you

A real email app, on the web and on your phone. It looks and works like the email you already know, and every message your agents handle shows up there too.

  • Read, write, search and organize
  • See every message your agent sent and received
  • Change what each agent can do, any time
For your agents

A token-light API and webhooks. Your agent gets the inbox as clean JSON with only the fields that matter, and only the permission you chose.

  • Get a webhook the moment mail arrives, no polling
  • Reply inside the conversation
  • Write new messages, if you allow it

Same inbox, same history. When your agent answers someone, you see it in that inbox's Sent folder. When you step in, your agent sees that too.

How it works

Up and running in three steps.

01

Get your address

Create you@pombus.com in a minute. No domain needed. Connect your own later and open as many inboxes as you want — contact@, billing@, sales@, one agent on each.

02

Connect your agent

Create an API key and choose what it can do: read, read and reply, or read and send. One key per agent, one inbox each.

03

Work together

Your agent handles the inbox with you, reading clean JSON instead of raw mail. Everything it does shows up in the app, and every message is recorded.

You decide

An agent can only do what you allow.

Each agent reaches an inbox through its own API key. You pick how far it goes, and you can change it whenever you want. A key for billing can never touch sales.

read

The agent reads your mail. Good for sorting, summaries and alerts.

read and reply

The agent reads and answers inside conversations that already exist.

read and send

The agent uses the inbox fully: it reads, replies and writes new messages, one person at a time.

You stay in charge

Your inbox, your rules.

Every message is signed and recorded, your agents read it without burning tokens, and you can pause them whenever you want.

DKIM · SPF · DMARC on every message Every message recorded, readable by you and your agents Pause all agents in one tap Clean JSON and webhooks, no polling One key per agent, with its own permission Unlimited inboxes on your own domain
A short manifesto

Why Pombus

Every agent deserves an address.

Email was built for a world where only people read email. Someone wrote it, someone opened it, someone replied. Every rule, every client, every inbox was shaped around a pair of human eyes.

That world is gone. Today the biggest reader of email is a machine. Agents check inboxes, parse confirmations, answer customers, chase invoices. And they do it through APIs designed for a person clicking around a screen. Every message arrives padded with markup and headers nobody asked for. Thousands of tokens to learn one thing. And even then you only get half the service: reading is one call, replying is another product, sending needs a third, and nobody tells you when something new lands.

Pombus is a real mailbox. You open it in an app that looks like the email you already know. Your agent opens the same mailbox through the API. Same inbox, same history, same threads. The agent sees what you allowed it to see and does what you allowed it to do. Nothing more.

It is light on tokens because it was designed that way, not patched later. Clean JSON with only the fields that matter. Webhooks that tell you the moment mail arrives, so nobody has to poll. Scoped keys, one per agent, so a key for billing cannot touch sales.

Most people end up with more than one inbox. contact@, billing@, support@. Each one gets its own agent, on your domain or on pombus.com. You read them. Your agents run them.

Every agent deserves an address.
