Quickstart · Bun / Hono

Send transactional email through Envimaily's HTTP API (https://api.envimaily.com) with Bun / Hono.

1. Account & key

1. Sign up at https://app.envimaily.com/dev/signup
2. Create an em_ key under API keys
3. Copy the token once — it is not shown again

2. Example

// Bun + Hono
import { Hono } from 'hono';

const app = new Hono();
app.post('/send', async (c) => {
  const res = await fetch('https://api.envimaily.com/v1/emails', {
    method: 'POST',
    headers: {
      Authorization: `Bearer ${process.env.ENVIMAILY_API_KEY}`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      from: 'onboarding@envimaily.com',
      to: ['you@example.com'],
      subject: 'Hello from Bun',
      html: '<p>It works.</p>',
    }),
  });
  return c.json(await res.json(), res.status);
});

3. Without a verified domain

Use the shared test sender onboarding@envimaily.com and send only to the account owner email. After SPF/DKIM verification, send from your domain.
