Resend or Mailgun?

Resend and Mailgun take different approaches to transactional email. Resend is free up to 3,000 emails/mo (100/day), then paid plans run $20/mo for 50,000, $35/mo for 100,000, and $90/mo for 100,000, with overage from $0.90 / 1k; dedicated IP: $30/mo (Scale).

Mailgun is free up to 100 emails/day (~3,000/mo), then paid plans run $15/mo for 10,000, $35/mo for 50,000, and $90/mo for 100,000, with overage from $1.80 / 1k; dedicated IP: 1 included on Foundation 100k / Scale. Mailgun is known for flexible routing and inbound processing and easy migration from SendGrid (REST/SMTP/webhooks parity).

For a Next.js codebase, the choice usually comes down to free-tier headroom and developer experience versus deliverability guarantees. The default pick for Next.js: resend SDK + react-email, sent type-safely from a Route Handler. If a handful of emails absolutely must reach the inbox, weight deliverability more heavily; if you want the fastest start, favor the larger free tier and the better SDK.

Switch to Resend in one Route Handler

Most migrations are a one-call change. Here's the Next.js Route Handler for each top alternative.

import { Resend } from "resend";

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

export async function POST(req: Request) {
  const { to, subject, html } = await req.json();
  const { data, error } = await resend.emails.send({
    from: "noreply@yourdomain.com",
    to,
    subject,
    html, // was: sgMail.send({ to, from, subject, html })
  });
  if (error) return Response.json({ error }, { status: 500 });
  return Response.json({ id: data?.id });
}
