The modern email API for
Send, receive, and thread email through one typed API. Versioned templates, signed webhooks, and replies that land back in your app.
Watch a send land.
Give your agent a safe way to send.
Samva publishes machine-readable setup paths for API keys, CLI login, hosted MCP, and agent skill discovery, so coding agents can choose the right credential before they act.
Read auth.mdAPI key
Use a scoped key for server-side sends and unattended agents.
CLI login
Run the device flow when a human is driving setup from a terminal.
Hosted MCP
Point an OAuth-capable client at Samva and let discovery do the rest.
The API behind every email you send.
import { createClient } from "samva";
const samva = createClient({ apiKey: process.env.SAMVA_API_KEY });
const { data } = await samva.email.send({
to: "ada@example.com",
subject: "Your order shipped",
html: "<p>Order #1042 is on its way.</p>",
});Templates you can roll back.
- Versioned templates, where the version you publish is the one that sends
- Render server-side by passing a templateId and templateData
- Full version history, with one call to restore any earlier version
Built to land.
Domain authentication, suppression handling, and signed events are defaults, not add-ons.
How deliverability worksDeliverability, on domains you own.
- The DNS set generated for you: ownership TXT, DKIM CNAMEs, a MAIL FROM subdomain, and DMARC
- DKIM signing on your own domain, so mail goes out from your address
- Bounces and complaints suppressed for you, before they cost you reputation
Email is a conversation. Treat it like one.
Sends, replies, forwards, and bounces live on one conversation per contact, so a reply lands in your app with its whole history attached.
How receiving worksEvery email your product sends.
One API underneath all of it.
Password resets
OTPs and reset links that arrive before the user gives up.
Receipts
Order confirmations from a template you can roll back.
Onboarding sequences
Welcome series scheduled ahead of time, from your own domain.
Reply-driven support
Replies land back in your app, threaded to the customer.
Weekly digests
Product email in batches, with delivery you can verify.
Set it up your way.
In the dashboard yourself, or hand it to your agent.
Works with your agent.
Hosted MCP gives any OAuth-capable client templates, contacts, and delivery status as tools.

Still deciding?
Ask a model you trust, or a person on the team.
Is there a free tier?
Yes. New accounts send test email free before picking a plan. Paid plans start at $5 a month for 15,000 emails, in your own currency.
How does threading work?
Outbound sends, replies, forwards, and bounces group into one conversation per contact. Inbound email arrives parsed with the same conversation id, so replies land back in your app with context.
Do you sign webhooks?
Yes. Each delivery carries an HMAC-SHA256 signature in the X-Webhook-Signature header, and Samva retries failed deliveries with backoff.
Can I bring my own domain?
Yes. Add your domain, publish the DNS records Samva generates, and your mail goes out from your own address, signed with DKIM.
What about deliverability?
SPF, DKIM, and DMARC run on your own sending domains. Samva handles bounces and suppression for you, and exposes delivery telemetry so you can verify each send.
Where does Samva run?
The API is served from a global edge network, close to your servers, with delivery through established email infrastructure. EU GDPR consent and unsubscribe handling are built in.
