Bun

Send your first email from a Bun server using the mailblastr SDK.

Send your first email from a Bun app using the mailblastr SDK. Bun reads .env automatically and is fully compatible with the Node SDK. Install it with bun add mailblastr, then import MailBlastr and call mb.emails.send().

Prerequisites

1. Install the SDK

bun add mailblastr

2. Add your API key

Bun loads .env automatically and exposes it on process.env / Bun.env.

.env
MAILBLASTR_API_KEY=mb_xxxxxxxxx

3. Send email from a Bun server

Create index.ts, instantiate the SDK client, and call mb.emails.send() from the request handler. Start it with bun index.ts.

index.ts
import { MailBlastr } from 'mailblastr';

const mb = new MailBlastr(Bun.env.MAILBLASTR_API_KEY);

const server = Bun.serve({
  port: 3000,
  async fetch() {
    const { data, error } = await mb.emails.send({
      from: 'Acme <onboarding@yourdomain.com>',
      to: ['delivered@example.com'],
      subject: 'Hello World',
      html: '<strong>It works!</strong>',
    });

    return Response.json(error ? { error } : { data }, {
      status: error ? 500 : 200,
    });
  },
});

console.log(`Listening on http://localhost:${server.port} ...`);
A successful call returns the created email's id. See the full request body in the Send an email reference.
