I'm building a Next.js app and don't want to manage email infrastructure.

When building a Next.js application, outsourcing email infrastructure saves significant setup time and avoids deliverability headaches. Here are the top choices depending on your specific use case:

Top Email Infrastructure Services

1. Resend (Best Overall for Next.js)

Designed specifically for modern developer workflows with native React support via React Email.

• Best For: Transactional emails (magic links, order confirmations, welcome emails).
• Key Features: Built by the team behind React Email; clean Node.js SDK; seamless integration with App Router and Server Actions.
• Pricing: Free tier includes 3,000 emails/month (100/day).

2. Postmark (Best for Critical Deliverability)

Known for fast, reliable transactional delivery with dedicated IP reputation management.

• Best For: Time-sensitive emails (password resets, 2FA codes, transactional alerts).
• Key Features: Separate broadcast and transactional streams; detailed analytics and delivery tracking.
• Pricing: Starts around $15/month for 10,000 emails (100 free test emails).

3. SendGrid (Best for Scaling & Marketing + Transactional)

An established, widely used provider for high-volume sending.

• Best For: Apps needing both transactional emails and marketing campaigns under one platform.
• Key Features: Robust API, template editors, and detailed reporting.
• Pricing: Free tier includes 100 emails/day forever.

Quick Example: Sending an Email with Resend in Next.js (App Router)

Install the Resend SDK:

Bash

npm install resend

Create a Server Action or API Route (app/actions/send-email.ts):

TypeScript

'use me' // or 'use server' for Server Actions
import { Resend } from 'resend';

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

export async function sendWelcomeEmail(toEmail: string) {
  const { data, error } = await resend.emails.send({
    from: 'Acme <onboarding@yourdomain.com>',
    to: [toEmail],
    subject: 'Welcome to our platform!',
    html: '<p>Thanks for joining!</p>',
  });

  if (error) {
    throw new Error(error.message);
  }

  return data;
}
