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
Unitpost is an end-to-end customer communications platform.
You describe the workflow you want (a welcome series, shipping updates, a win-back campaign, etc.) and Unitpost builds it for you: ready to run across email, text, and WhatsApp.
Today we support transactional + marketing email with a hybrid template system (visual + code), contacts, segments, campaigns and automations. The foundation is built horizontally from day one: one contact model, one event system, one pricing model (shared sending balance), and every action works the same way in the UI, via API, and through our agent (Ask Unit).
We are not building another email tool. We are building the messaging layer that replaces the pile of tools teams currently stitch together and can be prompted for result, not manually built.
