Send with React Email

typescript

import { Resend } from 'resend';
import WelcomeEmail from './emails/welcome';

const resend = new Resend(process.env.RESEND_API_KEY);

await resend.emails.send({
  from: 'hello@yourdomain.com',
  to: 'user@example.com',
  subject: 'Welcome!',
  react: WelcomeEmail({ name: 'John' }),
});

Resend natively supports React components as email templates.

Send with Template

typescript

import * as postmark from 'postmark';

const client = new postmark.ServerClient(process.env.POSTMARK_TOKEN);

await client.sendEmailWithTemplate({
  From: 'hello@yourdomain.com',
  To: 'user@example.com',
  TemplateAlias: 'welcome',
  TemplateModel: { name: 'John' },
});

Postmark uses server-side templates with variable substitution.
