An inbox that puts your important people first

4th Office works with your existing email and makes it all about connecting with real people again. By redesigning your inbox around your contacts and giving each one their own stream, we've banished clutter so you can focus on the important stuff and get more done.

An inbox that drives productivity

Too busy to respond to important emails? Our Follow-up feature lets you batch messages and get back to them at a specific times, so you can stay focused on the task in hand.


An inbox that supercharges your collaboration

Noticed how we’re increasingly jumping out of our inbox to use collaboration tools like Slack? 4th Office’s ‘Team’ feature allows you to collaborate and work on group projects inside your inbox, alongside your personal email for the first time!
