Run every client’s newsletter from one platform.
Stop stitching together a different tool for every account. Produce, monetize, and report on all of your clients’ newsletters from one place — with a separate workspace, brand controls, and clean reporting for each.
- A separate, governed workspace for every client — no crossed wires
- Lockable brand templates so every send matches each client’s brand
- Client-ready reporting on engagement and revenue, per account
- Layers on whatever stack each client already runs

Built for multi-client work
One login, every account.
A workspace per client
Separate, governed spaces so each client’s titles, audiences, and data stay cleanly their own.
Brand governance
Lockable templates keep every send on-brand for each client, no matter who on your team hits publish.
Client-ready reporting
Per-account reporting on engagement and revenue you can hand a client without rebuilding it in a deck.
A new revenue line
Stand up sponsorship, house, and programmatic inventory for clients — and take a cut of what you help them earn.
Production at scale
Drag-and-drop editions and reusable templates so a new account doesn’t mean a new workflow.
Fits each client’s stack
Layers on whatever ESP, CMS, and CRM a client already runs. No migration to sell them on.
“They’ve been the best kind of partner — striving to understand our needs, quick to respond, and building for the future.”
— Simone Wilson, Senior Manager, Patch.com
What agencies ask.
Can we keep clients separated?
Yes. Every client gets a separate, governed workspace — their titles, audiences, templates, and data stay cleanly their own.
Can we report per client?
Yes — engagement and revenue reporting is per account, so you can hand each client a clean read without rebuilding it by hand.
Do our clients have to switch tools?
No. Letterhead layers on whatever stack a client already runs, so there’s no rip-and-replace to sell in. Send with Letterhead or keep their ESP.
How does pricing work for multiple clients?
