Why we exist
The digital transformation of business infrastructure is not finished at email.
Every other layer of the modern stack, compute, storage, payments, has been rebuilt around developer-first primitives and usage-based pricing. Transactional and marketing email mostly has not. Mailflow is that rebuild: a transmission system designed around an API first, a dashboard second.
Built to replace rigid, legacy notification software
Legacy providers were built for marketing teams clicking through a template builder, not for engineers wiring up a send path. Mailflow strips that down: a raw template array, a metadata object, and a webhook stream, so your notification layer is as testable and versionable as the rest of your codebase.
How we got here
From a side project to a send-path engineers trust
Problem
A brittle send path
Notification email kept breaking under load, and every fix meant reverse-engineering someone else's dashboard instead of reading a spec.
Approach
API-first, dashboard second
We designed the send, template, and webhook contracts first, then built a dashboard on top of the same API every customer calls.
Proof
Deliverability that holds at scale
Warm IP routing and continuous reputation monitoring were built in from the first thousand sends, not bolted on after a spam-folder incident.
Today
One-time credit pools, no lock-in
Pricing stayed a pool of credits you buy once and draw down, not a recurring seat license you have to renegotiate every renewal.
