Hono

Send your first email from a Hono app using the mailblastr SDK. The SDK uses the standard fetch API and works on Node.js, Bun, Cloudflare Workers, and other edge runtimes. Install it with npm install mailblastr, import MailBlastr, and call mb.emails.send().

Prerequisites

• A MailBlastr API key.
• A verified domain to send from.

1. Install the SDK

npm install mailblastr

2. Add your API key

Store your key in the environment. On Node.js or Bun it is available as process.env.MAILBLASTR_API_KEY; on Cloudflare Workers it comes from the request context bindings (c.env).

MAILBLASTR_API_KEY=mb_xxxxxxxxx

3. Send email from a route

Create index.ts, instantiate the SDK client, and call mb.emails.send() inside a route handler.

import { Hono } from 'hono';
import { MailBlastr } from 'mailblastr';

const app = new Hono();
const mb = new MailBlastr(process.env.MAILBLASTR_API_KEY);

app.get('/', async (c) => {
  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 c.json(error ? { error } : { data }, error ? 400 : 200);
});

export default app;
