How It Compares
Beyond What Cloud Email Services Offer
More Than a Delivery Problem
Cloud email services solve delivery. The Email Api solves the complete problem: encrypted address storage, hash-based lookups, delivery, verification workflows, and bounce handling — in a self-hosted, sovereignty-preserving service that never exposes your users' addresses to a third party.
