Tired of Renting Our Identity
Why We Started ServerlessInbox
The idea for ServerlessInbox didn't start in a boardroom; it started with an ever increasing monthly invoice for a mailbox that was scanning our data to sell us stuff.
We realized that in the current landscape, you have two bad choices: surrender your data & privacy to 'Big Tech' providers, or spend your weekends patching Linux kernels and fighting with Postfix configurations to self-host a traditional mail server.
The Better Option
We wanted a third option. We wanted the privacy of self-hosting with the 'zero-maintenance' luxury of the modern cloud. We built ServerlessInbox because we believe you shouldn't have to be a full-time DevOps engineer just to own your own email.
Our Mission
Democratizing the Sovereign Mail Server
Our mission is to make data sovereignty the default by replacing the fragility of 30-year-old protocols with the JSON-native efficiency of JMAP.
By leveraging AWS Serverless architecture, we’ve removed the barrier to private communication—delivering a stack that is more affordable, secure, and significantly faster than legacy alternatives.
Total Data Sovereignty
We believe you shouldn't have to choose between convenience and privacy.
Our mission is to provide the tools that allow you to own your entire communication stack, ensuring your data never leaves your encryption keys or your AWS perimeter.
Zero-Ops Infrastructure
We want to remove the 'Maintenance Tax' of self-hosting.
By architecting everything around AWS Lambda, S3, and DynamoDB, we provide a production-ready mail server that requires zero patching, zero server management, and scales automatically.
Modern Protocol
Email is evolving, and we are leading the charge.
Our focus is on the widespread adoption of JMAP—a modern, stateless protocol designed for the mobile and AI era—ensuring your inbox is as fast and programmable as the rest of your modern tech stack.
Our Core Principles
The Code We Live By
Privacy is Binary
You either own your data, or you don't. By running 100% on the customer's side, we ensure we never even see your 'Subject' lines.
Performance Without Bloat
We chose Go for our core Lambdas because speed and memory efficiency translate directly into lower AWS bills for you.
Open Core Transparency
While our core logic is optimized as compiled binaries, our deployment infrastructure and APIs remain open-source. Trust, but verify.
Reputation Matters
We believe a mail server is only as good as its deliverability. Our built-in SES protections are designed to keep your domain out of the 'Spam' folder forever.

The People Behind ServerlessInbox
