"It's the first tool I've tried of many that have actually captured my voice in the responses that it drafts."

"I'm an executive who was drowning in hundreds of daily emails and heavily dependent on my EA for email management. What I love most about Inbox Zero is how it seamlessly replaced that entire function—the smart automation, prioritization, and organization features work like having a dedicated email assistant built right into my workflow."

"I was mostly hoping to turn my email inbox into less of the mess that it is. I've been losing tasks that I should do as the emails get buried. So far it's really helped."

"Finally an "unsubscribe app" that let's you *actually* unsubscribe and filter using Gmail filters (instead of always relying on the 3rd party app to filter those emails). Big plus for me, so I have all filters in one place (inside the Gmail filters, that is). Awesome work! Already a fan :)"
