Most business email hosts charge per mailbox and make you verify DNS by hand. Email Inbox gives your business a catch-all inbox on your domain — one inbox that catches every address, with send, search, and threading — provisioned automatically on Cloudflare, with no per-seat pricing.
One catch-all inbox covers the whole business domain
No per-mailbox seat cost
Automatic DNS, MX, and SPF setup
Search every conversation from one place

Authorize Kiap to manage Email Routing and deploy a Worker. One scoped OAuth consent screen — no API tokens to create or paste.
Pick one or more domains from your Cloudflare account. Kiap enables Email Routing, deploys a Worker, and wires a catch-all rule.
Kiap deploys a Worker per domain, turns on Email Routing with the right MX and SPF records, and creates the catch-all route. A few seconds per domain.
For a solo founder or small team, a catch-all inbox that receives every address on the domain is often enough — hello@, billing@, and the founder's name all land together and stay threaded. If you need separate private mailboxes per employee with isolated access, a per-seat host is a better fit.
No. Kiap deploys a Cloudflare Worker to your account and uses Cloudflare Email Routing for inbound mail. There is no Postfix, no Dovecot, and no server to keep patched. You approve one OAuth consent screen and Kiap provisions everything.
No. Authorization happens through Cloudflare OAuth. You approve a scoped consent screen in your browser. Kiap never sees your Cloudflare password and you never paste a token.
Yes — that is the whole point. Pick any domain on your Cloudflare account and Kiap provisions a catch-all inbox on it. Every address on that domain lands in your inbox by default.
Yes. Select one or many domains during setup. Each gets its own Worker and catch-all route, and all mail arrives in one inbox you can search and thread.
Yes. Outbound mail goes through the same Cloudflare Worker using Cloudflare's send_email binding, so you send from your own domain. Replies, reply-all, forwarding, HTML and plain text, and attachments are all supported.
Email Inbox runs on Cloudflare's free Email Routing tier and a free-tier Worker. You bring the domain. Check the Kiap pricing page for plan details.
Authorize Cloudflare, pick your domain, and you're sending from it in minutes.
