# Your brand out front, your controls underneath

> A white label email platform for agencies and OEMs: child workspaces under your brand, a roll-up console, per-child caps, and an instant kill-switch.

## Client email as a product you own

A white label email platform for agencies and OEMs: each client gets a child
workspace under your brand, and you get the console above them all. Per-child caps
and a kill-switch make the blast radius one client wide, not one agency wide.

## How it works

1. Create a child workspace per client — the surface they see carries your brand.
2. Run the book from the roll-up console: every child's activity and status in one place.
3. Set per-child caps, so one client's runaway campaign stops at their limit instead of consuming yours.
4. Hold the kill-switch: suspend a child instantly when a contract, an incident, or an unpaid invoice says so.

Rebilling — charging your clients through the platform — arms with billing at
launch. Until then, we bill you and you invoice your clients.

## The evidence

:::panel The control set, per child
- A workspace under your brand — your client's view of the product is yours
- Sending caps — enforced per child, set by you
- A kill-switch — instant suspension, held by the parent
- The roll-up console — the whole book on one screen
- Rebilling — arms with billing at launch

## Honest limits

:::tradeoffs Reputation has no white label
Branding changes what clients see, not how mailbox providers judge mail. Sending
reputation is earned per domain and per stream, and a client sending garbage will
feel it regardless of whose logo is on the dashboard. Caps and the kill-switch
contain the damage; they don't repeal the physics. And rebilling waits for billing
to arm at launch — plan your invoicing accordingly.

## Where to go next

Volume terms live on [pricing](/pricing). Many agencies run client
[newsletters](/features/newsletters) under this structure, and the surrounding
controls — identity, audit, custody — are behind the
[enterprise door](/enterprise). When a client asks how we stack up against the
platform they're on, the [comparison hub](/compare) has the honest answers.

## What do my clients see?

Your brand. Each client operates in a child workspace under your name — the platform underneath is ours, the relationship and the surface are yours.

## What happens when one client goes rogue?

Their cap stops the volume and your kill-switch stops the account — instantly, held by you, no support ticket in the path. The blast radius is that child workspace, not your whole book.

## Can I bill my clients through the platform?

Rebilling arms with billing at launch. Until then, we bill you, and you invoice your clients on your own terms.

## Does this work for OEM products, not just agencies?

Yes — the same child-workspace machinery serves OEM sub-accounts: embed email under your product's brand, with the same caps, console, and kill-switch.
