Earn 22% more on every monetized send.
That's the average lift after 180 days on Letterhead. Same audience, same inventory. The difference is slots that don't sit empty, fulfillment that runs itself, and reporting sponsors renew on.
Our tools
What drives revenue growth.
Inventory & calendar view
Sponsorship slots and house promos across every newsletter, mapped by date and zone — active, draft, and scheduled in one view.
Automated fulfillment
Scheduled placements run themselves. Editorial and revenue stop fighting over the send button.
Fill unbooked slots
Open zones surface as available across the calendar, so unsold inventory gets a CTA instead of a blank space.
Programmatic ad support
Native integrations with the major ad servers. Pick which slots go programmatic and which stay direct-sold.
Plays with your ad stack
Run programmatic or your own ad server? Letterhead sits alongside and runs the workflow on top. We don't replace your ad-tech.
Sponsor reports
Auto-generated proof-of-publication tearsheets with placements, impressions, and clicks. Formatted the way sponsors expect.
Revenue analytics
Per-send, per-sponsor, per-brand revenue in the same workspace as your editorial signal.
House promos & cross-promotion
Cross-promote your other newsletters, paid tiers, and events without coordinating with editorial each send.
