Drop-in support inbox
Give your tiny app a real support@ that triages and AI-drafts replies — without buying Zendesk.
Built on Cloudflare Email Workers
Your app's emails
finally reply back.
Sending email is solved. Receiving it isn't. Point a domain at ReplyFlow and every reply arrives as clean, threaded, intent-tagged JSON — quoted history and signatures stripped — ready for your webhook. No SMTP, no DNS rabbit-hole, no helpdesk.
Made for people shipping apps on Lovable, Bolt, v0, Cursor & Replit.
Live demo · runs in your browser
A messy reply in. Clean JSON out.
Pick an example (or paste a real reply), then watch ReplyFlow strip the noise and tag the intent.
This is the actual cleaning & intent step, running client-side. In production it happens at Cloudflare's edge the instant the email lands — then hits your webhook in milliseconds.
The gap nobody warns you about
You shipped the app. A user hit reply. It vanished.
You wired up Resend to send a notification in ten minutes. Then a customer replied to it — and the message fell into a void, or a personal Gmail that never gets checked.
Handling inbound mail means MX records, SPF/DKIM, an inbound parser, stripping quoted history, threading by Message-ID, storing attachments, filtering spam. That's a week of plumbing for something that should be one line.
ReplyFlow is that one line.
How it works
Three steps. Zero infrastructure.
1
Point your domain
Add one MX record (or use a @replyflow.com address). We handle SPF, DKIM & spam at Cloudflare's edge.
2
We clean every reply
A Cloudflare Email Worker parses the message, strips quotes & signatures, threads it, and tags the intent.
3
You get JSON
A signed webhook hits your app with structured data. Or use our drop-in inbox & AI auto-reply.
Recipes
The things you actually want to build.
Reply-to-confirm
“Reply YES to approve.” Turn a plain-English reply into a clean webhook event your app can act on.
Two-way threads
Marketplace messages, comments, support — let users reply by email and pipe it straight back into your app.
Human-in-the-loop
Email a human mid-workflow, pause, and resume when they reply. Approvals for your agents & automations.
