Cloudflare Email Service plans and prices

Cloudflare Email Service outbound sendingCloudflare Email Service outbound email (Email Sending) in USD list prices. The Email Service pricing page prints no separate fee for sending: it prints 3,000 emails included a month and then $0.35 per 1,000, and says sending to arbitrary recipients requires the Workers Paid plan. The monthly figure here is that plan's fee, printed on the Workers pricing page as a minimum charge of $5 per month for an account; the plan also covers Workers, Pages Functions, Workers KV, Hyperdrive and Durable Objects usage, so it is not a charge for email alone. Inbound email through Email Routing is unlimited and not priced here.

Who it suits

Applications already on Workers that need to send from the same platform they run on — one binding, no separate vendor, and inbound routing free and unlimited alongside it.

Consider something else if…

You need to send on a free plan, or you need volume pricing. Outbound to arbitrary recipients is unavailable on Workers Free, and the paid allowance of 3,000 a month is small next to a dedicated email provider's.
