Sh4yy/cloudflare-email
This is a simple proxy server that can be used for sending free transactional emails through Cloudflare workers.
A Cloudflare Worker that proxies email sends through MailChannels, letting you trigger transactional email via a simple HTTP API. The pitch was 'free email from a Worker' — but MailChannels killed the free tier for Cloudflare users in August 2024, so that pitch is dead. The repo is essentially a working skeleton with a tombstone notice at the top.
The HTTP API surface is clean and covers the real cases: plain text, HTML, multiple recipients, CC/BCC, reply-to, named senders. Bearer token auth is straightforward and the Wrangler secret setup keeps credentials out of source. SPF and DKIM setup instructions are included and accurate. Codebase is tiny (~5 files of real logic), so reading the whole thing takes ten minutes.
The core value proposition is gone — MailChannels no longer provides free sending for Cloudflare Workers, so anyone deploying this today needs a paid MailChannels account, which removes the main reason to use this over Resend, Postmark, or SES. No retry logic, no delivery status callbacks, no bounce handling — it fires and forgets with no visibility into what actually happened. No rate limiting on the worker itself, so a leaked token means your MailChannels quota gets hammered. The repo hasn't been updated to reflect the new reality beyond the warning banner, so the README still reads like the free tier exists.
