typescript

import Boundry from '@boundry/sdk';

const client = new Boundry({
  apiKey: Deno.env.get('BOUNDRY_API_KEY'),
});

export async function sendWelcomeEmail(to: string) {
  return client.emails.send({

    subject: 'Welcome to Acme',
    html: '<p>It works.</p>',
  });
}

Production checklist

Send only from a domain verified in this regional project.
Move user-facing sends to the framework’s job system when available.
Reuse an idempotency key if you retry after an uncertain response.
