Revolutionizing Email Management with AI
AI-Processing
Caja One’s AI seamlessly integrates with your Microsoft 365 environment to categorize, prioritize, and streamline email management — so you don’t have to.
Every sent and received mail is processed by AI models, resulting in a clean and actionable inbox, so you can focus on what is important.
Mass Unsubscribe
Caja One knows your inbox. As soon as you open the add-in, it shows a list of marketing emails that have already been categorized by the Caja One engine.
With a single click, you can instruct Caja One to unsubscribe you from selected newsletters—no need to search or filter manually. Caja One’s AI-powered engine handles the heavy lifting, keeping your inbox free from clutter.
We are the only multi-region AI Inbox Manager
Caja One is hosted on Azure in USA and Europe, with geographic tenant isolation.
Your email is processed exclusively within your designated geographic zone. Caja One is built with a security first mindset. and operates in a fully isolated environment with no inbound connections, eliminating external threats.
Most importantly, we ‘process and drop‘ email – data is not stored on our servers, and your data is never used to train AI models.
GDPR & HIPAA
At Caja One, we are committed to maintaining the highest standards of privacy and data protection. We build on Microsoft Azure, a platform that supports strict HIPAA and GDPR compliance standards.
We have implemented comprehensive measures to ensure full compliance with both HIPAA and GDPR.
