Grow the portfolio, not the workload.
Workspaces, governance, and a real portfolio-wide view of every brand, audience, and goal.
Letterhead helps you run every newsletter like a product, separate each brand and workstream, and combine precise targeting with global controls and data, like no other technology in the market can.
The challenge
You should be managing growth, not herding cats.
Most teams hit a wall the same way: more brands, more newsletters, or more audiences create multiplying complexity without multiplying results, because it's chaos to manage. Portfolio solves this, putting you in control at every step. You'll feel like you got superpowers.
What it looks like today
- A spreadsheet of newsletters nobody can fully own.
- Brand standards drift across products and people.
- It's hard to track each product over time separate from others.
- Permissions are hard to manage (or nonexistent).
- Goals are in meetings and spreadsheets, not your newsletter system.
- Content and templates can't be shared across newsletters.
- Someone's spending hours a week managing templates.
What changes with Portfolio
- A workspace per brand or title, all under one roof.
- Set and track goals for each newsletter and the total program.
- Brand and design governance enforced across every send.
- Real portfolio reporting across newsletters, audiences, and goals.
- Role-based permissions and version histories.
- Launch new newsletters in seconds.
How Portfolio works
What if the work behind the work did itself?
Workspaces
A workspace for every newsletter, brand, or title. Shared templates and rules above, local control below.
Brand governance
Lock the parts of the newsletter the brand depends on. Editorial moves fast on the rest.
Portfolio analytics
Every newsletter, brand, and campaign in one view. Compare apples to apples.
Roles & permissions
Role-based access for editors, audience, revenue, and leadership. Everyone sees what they should.
Portfolio health
Track changes, operations, and alerts across your entire operation in one easy place.
Goals & strategy tracking
Set goals for each newsletter and the whole portfolio, then watch above- or below-target status update itself.
Launch newsletters in seconds
Spin up a new title from a shared template, pre-wired to your brand rules and reporting.
Cross-product workflows
Share data, templates, and workflows across every newsletter instead of rebuilding them per title.
