Welcome to Flarepipe Docs

Learn how to configure Flarepipe to route your WordPress transactional emails through the Cloudflare Email Routing infrastructure.

What is Flarepipe?

Flarepipe is a WordPress plugin that replaces the default wp_mail() function. Instead of sending emails through local web servers or paying per-email services like SendGrid, Flarepipe uses the Cloudflare Worker Email Routing API.

By routing through Cloudflare, you get a generous sending quota of 1,000 emails per day (~30,000 per month) simply by using their \$5/month Workers Paid plan—saving you \$20-\$35+ per month compared to traditional SMTP providers.

Prerequisites

  • A WordPress website (version 6.0+)
  • A Cloudflare account (Free tier is fine)
  • Your domain's DNS must be managed by Cloudflare
  • Cloudflare Workers Paid Plan (\$5/mo) - to unlock outbound email capabilities via the API

info Important Note on Usage

Flarepipe and Cloudflare Email Routing are strictly for transactional emails (like WooCommerce receipts, password resets, and contact form submissions). Do not use this setup to send bulk marketing newsletters.
