Email

Business email without SMTP credentials or IMAP polling: Avunu's open-source Cloudflare Email suite for Frappe, Odoo and WordPress. Outbound mail goes straight to the Cloudflare Email Sending API, and inbound mail is stored by a relay Worker and pushed to your system as a signed web request, so a message is delayed rather than lost.

Getting Started

The Cloudflare Email Service documentation covers onboarding a domain and Email Routing. Start with the architecture overview, then follow the guide for your platform.

Concepts

• Email Without SMTP for Business Systems — The design: API sending, a store-first inbound relay, and the limits to plan around.

Platform Guides

• Cloudflare Email for Odoo — Install the mail_cloudflare module, configure outgoing and incoming mail servers, and test the webhook.

• Cloudflare Email for Frappe and ERPNext — Install cloudflare_email_delivery, set up the Email Domain and Email Account, and rotate the webhook secret.

• Cloudflare Email for WordPress — Route wp_mail() through Cloudflare with wp-config.php constants and use the send log viewer.

Deployment & Operations

• Deploying cloudflare-email-relay — Deploy the multi-tenant relay Worker with R2, Durable Objects, tenants, secrets, routing and the ops API.

• Troubleshooting Cloudflare Email — Symptom-first checks for mail that is not sent, not received, delayed, rejected or blocked by limits.
