About

Cloudflare Email Service is a cloud email platform for developers building applications, automated workflows, and AI agents. It combines outbound transactional email delivery with inbound email routing and programmable processing. Applications can send through a Workers binding, REST API, or SMTP, while incoming messages can be routed to Cloudflare Workers for validation, transformation, forwarding, and workflow automation. The service supports domain onboarding with SPF, DKIM, and DMARC configuration, and provides delivery logs and account-level controls. Developers can use it to send notifications, account and transaction messages, receive replies, process inbound messages, and connect email events to application logic. It requires Cloudflare DNS and uses the Cloudflare Workers platform for service access and billing; it is not a hosted mailbox or general-purpose email client.

About

SuperMailOS is managed business email on your own domain for small teams. You bring your domain; SuperMailOS runs the mail server and handles deliverability — SPF, DKIM, DMARC, IP reputation, and warmup — so your email lands in the inbox, not the spam folder. Setup takes minutes: verify your domain with one-click DNS on Cloudflare, DigitalOcean, and other providers (or guided copy-paste on any registrar), invite your team, and start sending. Every person gets a real mailbox; aliases like hello@ and support@ are unlimited and free. Webmail is as simple as Gmail — threads, instant search, keyboard shortcuts, labels, dark mode — plus IMAP and SMTP for any mail app, and a live deliverability dashboard showing your mail landing. Flat pricing per mailbox: Pro $3/mailbox/month annually (10 GB, 3 domains), Business $5 (30 GB, unlimited domains), custom at 50+. 14-day free trial, no credit card.
