Zero - Secure & Smart Email and Calendar

Mailfeed, Inc.
Zero has been designed with two important elements in its DNA. First is artificial intelligence. We do believe that with the help of A.I. you can be more productive with your email. Second is privacy. We believe that your personal data belongs to you and to you only. We have spent years to build an A.I. that works on your phone without sharing anything to anywhere outside of your device. This is Zero – A.I. driven productivity meets an enterprise-grade security.

Zero is a loaded with wonderful productivity features and here are just some of them:

TOTALLY NEW INBOX – you can see your emails in 3 different ways.
1. List View - shows your emails in an old good style.
2. Triage View – emails as a “tinder-style” cards that can help you get through thousands of emails really fast. Swipe to the left to archive/delete or to the right to keep in the inbox.
3. Senders View – see your emails grouped by people. Mute or delete all emails from one sender with a couple of taps.

Zero shows you the emails from people and contacts in a “Primary” tab and newsletter in the “Other” tab so your inbox doesn’t get polluted with less important emails.

Your personal A.I. assistant can remind you of the important emails you have missed. It can help you to archive a batch of emails that you don’t need in your inbox. It can also show you your email statistics and performance and suggest you how to improve it.

A.I. can sort your messages by importance showing you the most important emails on the top.

Zero has a calendar built-in so you don’t have to switch to a separate calendar app to check your schedule.

Now you can unsubscribe from unwanted emails with one tap.

Zero has a lot of pre-written email templates built in to save time on typing. Of course, you can add your own templates too.

Gmail, Yahoo, iCloud, Outlook, Hotmail, Office 365, MS Exchange, any IMAP enabled server.

Zero has been built in the heart of Silicon Valley by a passionate team that wants you to be more productive with email. We hope you’ll like it. Let us know if you have any comments or suggestions at
