CFEG — Cloudflare Email Gateway

Table of Contents

CFEG is a Worker gateway on Cloudflare Email Routing: keep what hits your domain when you want, forward on your terms, and send From the address the sender wrote to — including catch-all privacy locals — without adding every alias under Gmail Send mail as.

Problem
#

  • Forwarding is lossy — destination down, mailbox full, rate limits → mail can vanish if the forward was the only copy
  • Many identities — catch-all privacy (netflix@…, github@…, …) does not fit Gmail Send mail as at scale

What it does
#

CapabilityNotes
Archive (optional)Durable inbound keep when enabled
Forward (optional)Independent of archive — both, either, or policy-driven
Reply / compose hopReal From via tokens — not per-alias Send mail as
