Dead Simple Email — Python SDK for the email API for AI agents

Dead Simple Email — Python SDK

The official Python SDK for Dead Simple Email, the email API for AI agents.

• Typed responses — dataclass models with IDE autocompletion, not raw dicts
• Sync + async — DeadSimple for synchronous code, AsyncDeadSimple for async/await
• Idempotency — pass idempotency_key to any create/send method for safe retries
• Webhook verification — HMAC-SHA256 signature validation built in
• Full API coverage — inboxes, messages, threads, webhooks, domains, API keys, pods, usage, attachments

Install

pip install deadsimple-email

Quick Start

from deadsimple import DeadSimple

client = DeadSimple("dse_your_api_key")

# Create an inbox
inbox = client.inboxes.create(display_name="Support Bot")
print(f"Inbox: {inbox.email}")

# Send an email
result = client.messages.send(
    inbox_id=inbox.inbox_id,
    to="[e-mail]",
    subject="Hello from my AI agent",
    text_body="This email was sent by an AI agent using Dead Simple Email.",
)
print(f"Sent: {result.message_id}")

# Read received messages
messages = client.messages.list(inbox_id=inbox.inbox_id)
for msg in messages.messages:
    print(f"  {msg.from_email}: {msg.subject}")

# Reply to a message
client.messages.reply(
    inbox_id=inbox.inbox_id,
    message_id=messages.messages[0].message_id,
    text_body="Thanks for your email!",
)

# List conversation threads
threads = client.threads.list(inbox_id=inbox.inbox_id)
for t in threads.threads:
    print(f"  Thread: {t.subject} ({t.message_count} messages)")

# Register a webhook for real-time notifications
webhook = client.webhooks.create(
    url="https://your-app.com/webhook",
    events=["message.received"],
)
print(f"Webhook secret: {webhook.signing_secret}")

Async Usage

from deadsimple import AsyncDeadSimple

async with AsyncDeadSimple("dse_your_api_key") as client:
    inbox = await client.inboxes.create(display_name="Async Bot")
    await client.messages.send(
        inbox_id=inbox.inbox_id,
        to="[e-mail]",
        subject="Hello from async",
        text_body="Sent asynchronously.",
    )

Bulk Operations

# Create 50 inboxes at once
result = client.inboxes.bulk_create([
    {"display_name": f"Agent {i}", "tags": ["batch-1"]}
    for i in range(50)
])
print(f"Created {result.created}, failed {result.failed}")

Custom Domains

# Add your domain
domain = client.domains.add("mail.yourcompany.com")

# Shows DNS records to configure
for record in domain.dns_records:
    print(f"  {record['type']} {record['name']} -> {record['value']}")

# Check verification
status = client.domains.verify(domain.domain_id)
print(f"Status: {status.status}")

Multi-Tenant Pods

# Create an isolated namespace for a customer
pod = client.pods.create(name="customer-acme", description="Acme Corp")
print(f"Pod API key: {pod.api_key['key']}")

# Use the pod's scoped API key for isolated access
acme_client = DeadSimple(pod.api_key["key"])
acme_inbox = acme_client.inboxes.create(display_name="Acme Support")

Idempotent Requests

import uuid

# Safe to retry — same key = same result, no duplicates
key = str(uuid.uuid4())
inbox = client.inboxes.create(display_name="Bot", idempotency_key=key)
inbox_again = client.inboxes.create(display_name="Bot", idempotency_key=key)  # Returns same inbox

Webhook Signature Verification

from deadsimple.webhooks import verify_signature

# In your webhook handler (e.g., Flask, FastAPI):
try:
    verify_signature(
        payload=request.body,
        signature=request.headers["X-DSE-Signature"],
        secret="whsec_your_signing_secret",
    )
    # Signature valid — process the event
except Exception:
    # Signature invalid — reject the request
    return Response(status_code=401)

Usage Metrics

usage = client.usage.get()
print(f"Plan: {usage.plan_name}")
print(f"Inboxes: {usage.inboxes['used']} / {usage.inboxes['limit']}")
print(f"Emails this month: {usage.emails['sent_this_month']}")

Error Handling

from deadsimple import DeadSimple, RateLimitError, NotFoundError, ValidationError
import time

client = DeadSimple("dse_your_api_key")

try:
    inbox = client.inboxes.get("nonexistent")
except NotFoundError:
    print("Inbox not found")
except RateLimitError as e:
    print(f"Rate limited, retry in {e.retry_after}s")
    time.sleep(e.retry_after)
except ValidationError as e:
    print(f"Bad request: {e.message}")
    for detail in e.details:
        print(f"  {detail['field']}: {detail['message']}")
