About us
We're here to fix email.
Letterhead is building the intelligence layer for email. Newsletters are growth engines that have been constrained by outdated workflows — and the AI-powered tools to fix that have, until now, been out of reach. We're here to change that, send by send.
Our mission
Help brands realize email's full potential.
Through effective, efficient newsletters that people actually want. Email is the channel that stays yours when paid CAC climbs, when platforms shift, when AI floods the rest. We make software that turns it into a real growth engine.
The problem we solve
Email got harder. The tools didn't keep up.
Legacy tools were built for one-off sends or ecommerce — not for intelligent, content-driven newsletter portfolios. Teams keep getting forced into manual work; the insights that should sharpen each send sit buried in dashboards no one opens.
Modern newsletter programs need a different layer. One that thinks in audiences, content, governance, and revenue — and uses AI to improve each iteration without losing the editorial voice that earned the audience in the first place.
Who we are
A team obsessed with building better newsletters.
Strategists, engineers, and advocates with first-hand experience managing newsletter programs at scale. We've shipped newsletters under deadline. We've fought the templates. We've watched our team burn out on the work that wasn't the work. The platform we're building is the one we wished we had.
Based in Miami; team distributed across the US. 12555 Biscayne Blvd, Miami, FL 33127.
