Our Review
After spending time with Mail0 (also known as Zero), we're genuinely excited about how it's reimagining email management. While most email clients feel stuck in the past, Mail0's approach to combining AI with email feels refreshingly forward-thinking.
A Fresh Take on a Familiar Problem
What immediately caught our attention is how Mail0 transforms email from a passive inbox into an interactive assistant. Instead of just organizing messages, it actually helps you get things done. The ability to chat with your inbox in natural language and have it understand context is particularly impressive.
Open Source, Open Trust
In an era where AI transparency is crucial, Mail0's decision to open-source their entire codebase is a bold move that sets them apart. It's not just about trust — it gives tech-savvy users the freedom to self-host and customize their email experience. This level of transparency is rare in the AI email space.
Early Momentum Shows Promise
With 15,000 signups in just three months of beta, Mail0 has clearly struck a chord with users. The rapid adoption suggests there's significant demand for a more intelligent email solution, especially among professionals drowning in their inboxes.
Room for Growth
While Mail0's core features are compelling, we'd love to see more advanced collaboration tools and enterprise-focused features as they mature. Currently, it's best suited for individual professionals and small teams looking to upgrade their email experience.
For busy professionals tired of traditional email clients, Mail0 represents an exciting glimpse into email's AI-powered future. Their commitment to open source and rapid feature development makes them particularly worth watching as they evolve.
