import { Waymail } from "waymail";

const waymail = new Waymail(process.env.WAYMAIL_API_KEY);

// The key carries its region, so this reaches eu.api.waymail.app directly.
const { id } = await waymail.emails.send({
  from: "Waybound <hello@waybound.ai>",
  to: "user@example.com",
  subject: "Verify your account",
  html: "<h1>Hello from Waymail</h1>",
});

// → { id: "em_eu_01K4…", status: "queued" }  ·  returns in ~40 ms

What you get

Everything above the SMTP layer, done properly.

Every domain you own

Domains and subdomains are first-class. Add news.example.com beside example.com with separate tracking and DNS state for each.

See exactly what was sent

The rendered message, the plain-text part, the raw HTML, the headers — and every link, extracted and one click from being opened.

Delivery you can trace

Queued, sent, delivered, delayed, bounced, complained — as a timeline per message, with the SMTP response and diagnostic code attached.

Broadcasts that can't block a reset

Newsletters run on a separate queue with their own concurrency, so a hundred-thousand-recipient send never delays a password reset.

Suppression that understands intent

Unsubscribing from your newsletter stops the newsletter. It does not stop the account-security email that same person still needs.

Webhooks and MCP

Signed webhooks with replay, plus a regional MCP endpoint so an agent can find a message and pull the verification URL out of it.

Data residency

Choose your region. We won't move it.

A workspace is EU or US, permanently. Your API, queues, database, message bodies, encryption keys and logs all live in that region — and an EU workspace is never failed over to the US.

We say this carefully. Waymail stores and processes your email data within your selected region until it is delivered to the recipient's mail infrastructure. Once Gmail or Outlook accepts a message, where they process it is their decision, not ours — so we don't claim otherwise.

Regions immutable per workspace

eu.api.waymail.app: Frankfurt · eu-central-1
us.api.waymail.app: N. Virginia · us-east-1

The SDK reads the region from your API key and connects straight to that endpoint. No global router sees your message bodies on the way.

Developer experience

Built for the person who gets paged.

Retries that can't send twice

Pass an Idempotency-Key and a repeated request returns the original message instead of a second one. Same key, different body, and you get a 409 rather than a surprise.

await waymail.emails.send(email, {
  idempotencyKey: `welcome:${user.id}`,
});

Find the link, fast

"I never got the verification email." One call gets you every link in the message that was actually delivered — no digging through raw HTML.

const [email] = (await waymail.emails.list({
  recipient: "user@example.com",
})).data;

await waymail.emails.links(email.id);
// → [{ text: "Verify account", url: "https://…" }]

p95 < 300 ms

to accept and durably queue a message. Delivery happens after we've answered you.

100 per batch

messages in a single call, each with its own id and delivery history.

RFC 8058

one-click unsubscribe on marketing mail from day one — never on your password resets.

Pricing

Simple, and honest about what it costs.

Waymail is in private alpha and not yet sold. Commercial pricing lands with the beta. In the meantime, here is what the underlying delivery actually costs, so you can do the arithmetic yourself.

Volume	Transport cost	Notes
10,000	~$1	Amazon SES at $0.10 per 1,000
100,000	~$10	plus roughly $15–25/month of surrounding AWS
1,000,000	~$100	shared IP pool; dedicated IPs available later

Private alpha

Waymail runs Waybound's own products first. We're opening it to a small number of teams who send transactional email and care where it lives.
