What Letterhead is
Letterhead offers two newsletter products: Studio adds production tools to an existing email service provider (ESP), while Suite brings email operations together on one platform. Studio includes drag-and-drop editing, reusable and lockable templates, content curation and approval flows. Its intelligence tools report content performance and audience engagement and offer recommendations based on billions of sends. Revenue features cover direct and programmatic ads, house promotions and conversion calls to action. Suite adds a unified reader view, audience segments, journeys, triggered flows and preference management. It supports newsletter and transactional delivery, dedicated IP pools, migration and warmup, plus deliverability reporting and repair. Letterhead lists more than 30 integrations, including Mailchimp, Iterable, Braze, HubSpot, WordPress, Shopify and Google Ad Manager. Developers can use a versioned REST API, webhooks, Zapier and per-tenant MCP servers. The platform describes SAML single sign-on, workspace-scoped roles and audited SOC 2 controls. Letterhead is based in Miami, and pricing depends on newsletter count and audience size.
