Cloudflare Email Service
Free routing, programmable inbound via Workers, sending in beta.
Cloudflare Email Service bundles the long-standing free Email Routing product with Email Workers (programmatic inbound) and a new Email Sending API launched in public beta in April 2026. The combination is unique: a free forwarding tier, a TypeScript-native way to handle inbound mail, and a sending price near the bottom of the market. The sending product is brand new, so deliverability track record is nonexistent.
The question here is which one a backend engineer would rather operate. That means SDK depth in the language already in use, whether a retry can safely be replayed, how much the event log tells you when a customer says the email never arrived, and whether the pricing curve stays sane as volume grows.
Against password resets, receipts, and magic links shipped from application code, Cloudflare Email Service covers developer experience, SDK breadth, and event stream, and does not cover idempotency keys and webhook coverage. Whether that gap matters depends on how central those are to the build.

Domains already on Cloudflare that want free routing, programmable inbound, and a cheap sending API in one place.
Workloads that need proven deliverability today, or teams that prefer to keep email infrastructure off Cloudflare.
- › Email Routing is free, including catch-all addresses and forwarding to any inbox
- › Email Workers let you process inbound email in TypeScript with no extra infrastructure
- › Sending priced at $0.35 per 1,000 (about a third of most managed providers)
- › Native fit when DNS, Workers, and KV/D1 already live on Cloudflare
- › No separate API keys; auth is via Cloudflare API tokens
- › Email Sending is in public beta; no deliverability history yet
- › No SMTP relay; everything routes through Workers or the REST API
- › Templates and event-log debugging are minimal compared to Postmark or Mailgun
- › Tightly coupled to the Cloudflare ecosystem; not portable
- › Best-of-breed providers will outpace it on pure sending features for some time
