Audience-first campaigns
Your audience is people.
Your campaigns should treat them that way.
You already know what your subscribers care about. Letterhead lets you put that knowledge to work — different content for different people, sends that trigger on the right moment, and revenue built into every edition.

The world's leading newsletter teams run on Letterhead
Conditional content
One send. A different newsletter for every subscriber.
Bob follows the Giants. Alice follows the Senate. Same edition — different blocks. Letterhead shows each subscriber only the content that’s for them.
Included in Letterhead Suite. Conditional blocks require Letterhead’s integrated sending.

How it works
Three building blocks. Infinite combinations.
Know who’s reading
Every form fill, every click, every tag — Letterhead builds a profile of each subscriber. Sports fan or policy wonk, new sign-up or five-year reader.
Set the conditions
Write the newsletter once. Mark which blocks are for which audience. Letterhead assembles a unique edition for each subscriber at send time — no duplicate campaigns, no segmented lists.
Send the right version
Every subscriber gets the edition built for them. Bob opens a sports-first newsletter. Alice opens a politics-first one. Same send time, same sender, same brand.
Triggered sends
Send when it matters, not just when it’s scheduled.
The best moment to reach someone is right after they’ve raised their hand. A form fill, a tag, a signup — Letterhead can fire a send the moment a subscriber does something that tells you they’re ready.
Bob fills out the draft interest form
Tags him “NFL Draft interested” and captures his team preference.
Letterhead fires the trigger
“NFL Draft interested” tag applied → automation starts.
Bob gets the edition built for him
Draft preview, his team’s picks, local angle — delivered within minutes.

“Your Giants draft preview” — opened 4 minutes after delivery
Audience intelligence
Every interaction tells you something. Keep it.
Form fills, link clicks, open rates by segment — every signal builds a richer picture of who’s in your audience and what they care about. Letterhead stores it, surfaces it, and lets you put it to work in the next send.
Tags that compound
Every form field, every signup source, and every automation-applied tag builds the subscriber profile. Segments from real, collected data — not assumptions.
Segments that stay current
Dynamic segments update automatically as subscribers engage. The “high-intent” segment grows itself — you don’t rebuild it every week.
First-party, yours to keep
Everything you collect through Letterhead is first-party data owned by you — not a platform that can change its API terms tomorrow.
Works across your whole portfolio
One audience view across every newsletter you run. Bob’s sports preference from your city guide informs his experience in your business newsletter.
Monetization
You’re already building the most valuable thing in media.
Get paid for it.
A segmented, engaged audience is the inventory sponsors pay the highest rates for. Letterhead Promotions auto-inserts native ad placements into your sends and handles fulfillment and reporting automatically.
- Direct ad sales — sell inventory to sponsors at your own rates
- Programmatic fill — monetize unsold slots automatically
- Sponsor reports that write themselves
