For newsletters & creators

The list is yours. The inbox helps you write to it.

Picture your whole audience as rows you can read, segment, and write to — in a database on your own Cloudflare account, not behind someone else's export button. The assistant drafts the next issue from your notes for you to approve, journeys run the welcome series and the re-engagement on their own, and the relationship you spent years building stays yours. Growing it never quietly raises the price.

The old way

Your newsletter tool holds the thing you actually built.

You did the hard part — earning every name on that list. But it lives in someone else's account, on their terms, and the better it does, the more it costs you.

Every win quietly raises the bill

A post goes viral, a launch lands a wave of signups — and per-subscriber pricing turns each of those good days into a higher invoice next month.

The list you built isn't really yours

Export is grudging, deliverability is the vendor's call, and walking away means risking the audience you spent years earning.

You're billed for readers you never write to

Idle addresses keep counting against your tier, month after month, whether you've sent them anything or not.

The economics

Priced by what you send, not how many you've gathered.

One license on infrastructure you own. Your cost follows what you actually send — so a list that doubles doesn't double the bill.

$249

one-time license

not a monthly per-subscriber tier

3,000

sends/month on the free tier

then $0.35 per 1,000

100%

of the list is yours

exportable from your database anytime

What you get

A real sending stack, in a writer's hands.

Your audience, as rows you can read

Subscribers, segments, and engagement history are rows in a database you control. “Everyone who opened the last three issues but hasn't clicked a link” is a segment you can actually build — import by CSV, export anytime, query it with nobody in the middle.

The assistant drafts the issue with you

Hand it your notes — three links and a paragraph of thoughts — and it drafts the next broadcast in your voice for you to approve before it sends. Or wire a multi-step journey yourself: welcome series, re-engagement, drip, with open and click tracking on every message.

Signup forms with double opt-in

A hosted form on your domain (or a JSON endpoint for your site) captures subscribers with double opt-in and a honeypot built in. A clean list, no extra tool.

Deliverability you control

Send from your domain with your own DKIM/SPF and a ledger you can audit. Your reputation stays yours, never pooled with a vendor's other senders.

Two paths, five years out

Where this leaves you down the road.

A rented ESP

Monthly bill climbs with every new subscriber
Idle addresses still count against your tier
Export and deliverability on the vendor's terms
The list lives in their account, not yours

Tinbox, owned

One-time $249 license, paid back in ~2 months
Cost tracks sends, not list size
Your domain, your DKIM, your reputation
Subscribers in a database you keep for good

Questions

What you'll want to know.

How do I design my emails?: You write campaigns and journeys, send them from your own domain, and lean on the assistant to draft. Tinbox runs the list and the sending; there's no drag-drop layout builder, so if pixel-perfect templates are central to how you work, it's an honest poor fit.
How technical is it to get started?: One deploy to your own Cloudflare account: npx tinbox init and you're live. After that, day-to-day sending is just the app.
Can I bring my existing list?: Yes, import by CSV into an audience. Didn't collect it with confirmed opt-in? Re-permission it first; the double-opt-in flow is built for exactly that.

Why builders switch

What writers say.

“I stopped being punished for growing. The list lives in my own database now — it's an asset I own, not a bill that climbs every time a post does well.”

Stop being billed for growing.

The list lives in a database you own, the assistant helps you write to it, and the cost tracks what you send — not the audience you spent years earning. Yours to keep, for good.
