# Introduction

> AgentPost gives you on-demand disposable email addresses for privacy, testing, and AI agent automation.

AgentPost is a temporary email service that creates throwaway inboxes instantly. Use it to keep your real address private, test email workflows in staging, or give AI agents a real inbox to work with — all without touching your primary email account.

## What you can do

## Who it's for

**Privacy-conscious users** — Sign up for services, newsletters, or trials without exposing your real address. Delete the mailbox when you're done.

**Developers and QA teams** — Test transactional email flows (welcome emails, password resets, verification codes) against a real SMTP inbox in staging or CI.

**AI agent builders** — Give agents a working email address as part of automated workflows: sign up for a service, receive a verification email, extract the code, and continue — all without human intervention.
