Community Voice & Feedback
Congrats Elie on launching Inbox Zero Mail. Going from an AI layer on top of Gmail to your own open-source client is a big step, and self-hosting makes it an option for teams that can't hand their mail to another vendor. When the AI drafts a reply in my voice, does it learn from each account's sent mail separately, or one shared style across every inbox I connect? I write very differently from my work and personal addresses.
Congrats on the launch! Looks awesome
Really nice work on this, Elie! Looks great, congrats on the launch. Look forward to checking it out.
Running three years on Inbox Zero and then deciding to build the whole client around it is a bold move, and the split inbox plus bulk unsubscribe combo is why I stopped opening Gmail in a tab.
Congrats Elie!!
Congratulations on the launch!
