How to send emails with Deno

The Publiq SDK works in Deno via the `npm:` specifier. Run with network and env permissions.

Import straight from npm and set PUBLIQ_API_KEY in the environment:

import { Publiq } from 'npm:publiq';

const publiq = new Publiq(Deno.env.get('PUBLIQ_API_KEY'));

await publiq.emails.send({
  from: 'you@yourdomain.com',
  to: 'user@example.com',
  templateKey: 'welcome-email',
});

// deno run --allow-net --allow-env main.ts

Best practices

Always call Publiq from the server — never expose the API key on the client.
Create the client instance once and reuse it across requests.
Prefer templateKey over inline HTML to keep content versioned.
Handle PubliqError (status/code); the SDK already retries transient errors with backoff.
Send from a verified domain — see Domains.
