Built for developers
who ship.
Messy was born from frustration with bloated messaging platforms that try to do everything and end up doing nothing well.
The Problem
Every app needs to send messages. Welcome emails, order confirmations, password resets, shipping updates. The list grows with every feature you build.
Most teams end up with email logic scattered across dozens of services. SMTP credentials hardcoded in environment variables. Twilio API keys passed between microservices. Template strings buried in application code.
The alternatives? Platforms like SendGrid and Mailchimp that bundle marketing automation, cadence builders, and audience segmentation into what should be a simple message delivery tool.
The Solution
Messy does one thing: deliver messages. It provides a clean API layer between your application and your messaging providers. Templates live in one place. Credentials are isolated. Channels are configurable.
With the rise of AI agents that need to communicate with users, safe message delivery becomes even more critical. Messy lets agents interact with templates and merge tags without ever touching raw API keys or provider credentials.
Open Source First
Messy is open source because messaging infrastructure should be transparent. You should be able to audit how your messages are processed, stored, and delivered. You should own your delivery pipeline.
For teams that prefer a hosted solution, we offer cloud plans with the same feature set. No feature gating between open source and cloud.
