Infinite combinations. 1 ### 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. 2 ### 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. 3 ### 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.

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.
