Introducing Postflare

We're excited to announce Postflare — a modern email service SaaS built entirely on Cloudflare infrastructure. Whether you're sending transactional emails, marketing campaigns, or handling inbound email processing, Postflare has you covered.

Why We Built Postflare

The email infrastructure landscape has been dominated by a few legacy players for years. While they've served the community well, we saw an opportunity to build something faster, cheaper, and more developer-friendly by leveraging Cloudflare's edge network.

Speed at the Edge

Every email you send through Postflare is accepted at Cloudflare's edge — the same network that powers millions of websites worldwide — and then delivered asynchronously from a queue. This means:

• One global API — the same endpoint answers from anywhere
• Queued delivery — a send returns once Postflare has accepted the email, and delivery happens in the background, where a failed attempt is retried instead of holding up the request

Built for Developers

We believe email APIs should be as simple as possible. Here's all you need to send an email:

// Set RESEND_BASE_URL=https://api.postflare.dev in the environment before
// the process starts. Without it the SDK sends to api.resend.com, silently.
import { Resend } from 'resend';

const resend = new Resend('sk_xxxxxxxxx');

const { data, error } = await resend.emails.send({
  from: 'Acme <hello@acme.com>',
  to: ['user@example.com'],
  subject: 'Welcome to Postflare',
  html: '<p>Thanks for signing up!</p>',
});

Transparent Pricing

No hidden fees, no per-email surcharges for basic features. Postflare has four plans — Free, Pro, Business, and Enterprise. The Free plan includes 3,000 emails per month, up to 100 per day. Current prices for every plan are on the billing page in your dashboard.
