Why mark each new email as read ????


The concept of cards to read your email organised by regular sender is a good idea, however it then mark every new email received as already Read, and therefore you will not see them as unread in your other email app (yes, because sorry we cannot just use that app and get rid of the other mail client!), so I have revoked the email account permission and will not be using for now.

Too dangerous to miss an email.

Hi there! I am really sorry you experienced this issue on 4th Office at the time. In our current version, emails stay unread until you actually open them. You can also sign emails as unread when you need to go back to them. I advise you give a go to our app now and let us know what you think here on the App Store or by emailing us at Hope to hear from you soon. All the best, Francesca - Customer Care Team



Works great and is super user friendly. More people need to know about this!

Nope, it does not work for me


This thing does not work !!
After signing in , it takes you back to the startup screen & asks you to sign in again, and again .

Hello Khortagge! I am sorry the app didn't work for you at the time. We now know that our previous iteration has some limitations for some users. We have recently released a new version of the app where issues at log in stage have been resolved. Please give it another go and let me know how 4th Office performs this time.
