You spend the morning figuring out which emails matter and writing replies that all sound alike, while newsletters bury what is urgent. Inbox Zero labels every incoming email, leaves a draft reply in your voice on the ones that need an answer, and lets you unsubscribe in one click from the lists you never read.
Who this is NOT for
If your company email lives on cPanel-style hosting rather than Gmail or Outlook, it will not work for you: their site only offers connecting Google or Microsoft accounts. If 5 or more people will use it, the license rules out the free self-hosted route: you pay per user for the cloud or negotiate an enterprise license. And if you are an agency planning to resell it to clients, the license forbids that without written permission.
Even though it is labeled open source, its LICENSE adds custom terms on top of the AGPL that most people never read: it is only truly free for teams under 5 people. Against Fyxer, the comparison they make themselves, what you gain is seeing the code and setting rules in plain language. The mistake almost everyone makes is turning on drafts and sending them unread. Use it the first week only to sort and clean up, edit every draft before sending, and let it learn your voice before you trust it with customers. The project is alive: the last commit is from today.
Your first step

The project belongs to Elie Steinbock (elie222) and it is free: the link beside asks for nothing. The guide to set it up without getting lost is ours: step by step, common mistakes and a checklist. Leave your email and we will send it.
