Resend - Skillship

Send transactional email through a small Node.js SDK, with domain verification, React templates, scheduling, delivery events, and safe retries.

🧭 When to use this skill

• Use when: sending password resets, receipts, verification links, alerts, or onboarding emails.
• Use when: you want React Email templates and a straightforward HTTP email API.
• Don't use for: a full marketing automation platform with complex campaign journeys.

⚡ Quickstart

1. Install

npm install resend

2. Configure

RESEND_API_KEY=re_xxxxxxxxx

Create the key in Resend and add a domain you own. [e-mail] is test-only; production senders must use a verified domain.

3. Send from server code

import "server-only";
import { Resend } from "resend";

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

export async function sendWelcomeEmail(user: { id: string; email: string }) {
  const { data, error } = await resend.emails.send(
    {
      from: "Acme <[e-mail]>",
      to: [user.email],
      subject: "Welcome to Acme",
      html: "<strong>Welcome!</strong>",
    },
    { idempotencyKey: `welcome-user/` },
  );

   (error)   (error.);
   data.;
}
