Generate and send emails with AI (LLM)

Use an LLM (OpenAI, Anthropic, etc.) to draft the content and send it with Publiq — great for summaries, follow-ups and personalized replies.

Generate the HTML with the LLM and pass it inline in the send. Always validate/sanitize the model output before sending:

import OpenAI from 'openai';
import { Publiq } from 'publiq';

const openai = new OpenAI();
const publiq = new Publiq(process.env.PUBLIQ_API_KEY);

const res = await openai.chat.completions.create({
  model: 'gpt-4o-mini',
  messages: [{ role: 'user', content: 'Write a friendly welcome email in HTML for Acme.' }],
});
const html = res.choices[0].message.content ?? '';

await publiq.emails.send({
  from: 'you@yourdomain.com',
  to: 'user@example.com',
  subject: 'Welcome to Acme',
  html,
});

Prefer not to build HTML by hand? Publiq has an AI template builder in the dashboard — generate the template visually and send it by templateKey.

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.
