Stop giving bots your Google password.
Your AI agents need email — not access to your calendar, contacts, Drive, and docs. Dead Simple gives every agent a sandboxed inbox. Isolated, API-first, and 24x cheaper than Google Workspace.
from deadsimple import DeadSimple client = DeadSimple(api_key="dse_...") # Create an inbox — instantly ready to send & receive inbox = client.inboxes.create(name="support") # → support@yourco.deadsimple.email ✓ # Send an email inbox.send( to="user@example.com", subject="Your order has shipped", body="Tracking number: 1Z999AA10123456784" ) # Read incoming messages messages = inbox.messages.list() for msg in messages: print(msg.subject, msg.body)
100 Google Workspace seats: $840/mo → 100 Dead Simple inboxes: $29/mo
Google Workspace wasn't built for this.
Expensive at scale
$7-8.40/inbox/month. 100 agent inboxes = $700-840/mo. Dead Simple Pro: $29/mo for the same 100 inboxes.
Security nightmare
Google accounts hold calendars, Drive files, contacts, docs. Giving an AI agent access to all of that is a massive attack surface you can't afford.
Built for humans
OAuth flows, browser logins, IMAP configs. None of that works for headless AI agents that just need to send and receive.
Everything your agent needs to email
A complete email platform built from the ground up for AI agents and automation. No IMAP headaches, no SMTP configuration.
Instant Inboxes
Create fully working email inboxes via API. Each gets a unique address on your subdomain — no DNS configuration required.
Real-Time Webhooks
Get notified the instant a message arrives. HMAC-signed payloads delivered to your endpoint with automatic retries.
Send & Receive
Full two-way email. Send transactional messages and receive replies — your agents can hold real conversations over email.
Secure by Default
SPF, DKIM, and DMARC pre-configured. API keys are SHA-256 hashed. Per-customer data isolation. We handle deliverability so you don't have to.
Custom Domains
Use your own domain for a professional look. Automated DNS verification — just add the records and we handle the rest.
Developer-First SDKs
Python SDK on day one. TypeScript, Go, and more coming. OpenAPI spec included. Built for agents, loved by developers.
From zero to inbox in 60 seconds
Three steps. No server setup. No DNS headaches. Your agent gets a working email address instantly.
Get your API key
Sign up and generate an API key from the dashboard. Your shared subdomain is assigned automatically.
Create an inbox
One API call creates a fully functional inbox. Send and receive email immediately — no DNS, no waiting.
Send, receive, automate
Send emails via API, receive them via webhook. Your AI agent now has its own email identity.
Built for the age of AI agents
Every agent that interacts with the outside world needs an email address. Here's how teams use Dead Simple.
Customer Support Agents
AI agents that receive support tickets via email, understand context, and send intelligent replies — 24/7, with full conversation history.
Sales Outreach Agents
Each agent gets its own inbox for personalized outreach. Track replies, handle follow-ups, and manage conversations autonomously.
Workflow Automation
Receive invoices, parse order confirmations, process form submissions. Any email-triggered workflow, automated end-to-end.
Multi-Tenant SaaS
Give each of your users their own email inbox. Perfect for platforms that need per-user or per-project email capabilities.
Monitoring & Alerts
Receive system alerts via email, parse them with AI, and trigger automated remediation. Close the loop between notification and action.
Research & Data Collection
Subscribe to newsletters, collect email-gated content, aggregate information. Your AI agent handles the inbox while you get the insights.
