Give your team a team.
Letterhead agents can design templates, create layouts, curate content, prepare editions, manage the workflow, review your newsletters, analyze your data, and prepare reports.
You give the instructions, agents do the work — with controlled, brand-safe, powerful results — and you get your time back.
The challenge
Newsletters are still deeply manual, in all the wrong places.
Lots of tools now claim AI can assist. It tends to stop at drafting text or subject lines. The real work stays time-consuming and manual. Letterhead changes that.
What takes a human today
- Managing workflows and newsletter reviews.
- Checking each edition pre-flight.
- Building new templates and designs.
What changes with Agents
- Agents run the workflow and route each review for sign-off.
- Pre-flight checks run automatically on every edition.
- Agents build new templates and layouts, on brand.
How Agents works
Doing something on repeat? Agents can do that.
If you have a recurring workflow, step, or task that's taking your time, Letterhead can take it off your plate — running with your instructions, and reporting back for approval and review.
Your team of agents
You hand off the work; each agent runs its part and reports straight back to you.
What you get
Agents that do the operation, not just talk about it.
Built on the same APIs and per-tenant MCP server your team already runs — so an agent can do anything a person can do in-app, with the same permissions and audit trail.
Issue drafting
Point an agent at your sources and a brief. Get a first-draft issue in your template, ready to shape and approve.
Agentic curation
Agents pull and rank candidate stories against your brand guidelines and past performance. You keep the final pick.
MCP server
A per-tenant MCP server so an LLM can trigger sends, sync data, and act on changes with your permissions.
Insight on demand
Ask what's working across the portfolio and get an answer grounded in your real reporting, not a guess.
Bring your own agent
Connect Claude or any MCP client to your per-tenant MCP server, or drive the same operations through the v3 REST API.
