Unibox groups your emails by sender. Keeping control of your mailbox has never been this simple.

With Unibox your inbox is always cleaned up. You navigate through your emails by sender. With a single tap you can see all messages and attachments you exchanged with a person in one place. And with a single swipe you can get rid of dozens of newsletters and notifications of the same sender that you don't need anymore.

Unibox works with all email providers that support the IMAP protocol, including Gmail, Hotmail,,, Yahoo, Office365, Exchange servers that have IMAP enabled, self-hosted servers and many more.

Unibox is also available for Mac.

Keep coming back...


I have done extensive trials with most of the other email apps out there, spark, hop, airmail, etc. But this is the email app I keep coming back to, both in my Mac an iOS devices.
I keep searching because I wish unibox had a few features that I miss from the others: 1. Calendar recognition as link and better integration of invitations. 2. Color coding of different email accounts. 3. More swipe command options. 4. Better signature platform that allows images and font changes.
Why 5 stars? Because this is the best of what is available and I can survive without my wanted features. I just hope they deliver in a future version.

Great alternative email app


I have tried all the major email apps and while they are all reasonably functional for my needs, none fit my workflow or had the visual appeal I was looking for. That is until I came across Unibox. It was not until I tried this app that I realized that grouping emails by sender instead of a chronological list of emails like other apps not only fit better with my workflow, but made me realize that this is what I was looking for all along. Kudos to the developers for creating refreshing and efficient way of working with email. Looks like my search is finally over.

Five stars if I could get integration with cloud storage and other apps like to do apps.

Makes more sense


Simple and the way email should be.

An unexpected benefit of grouping emails by sender is that you can quickly locate and unsubscribe from junk and lists you don’t want.

Some things that need to be improved:

-I have toggled both fetch settings within the app but I rarely get notified I have new email. Instead I have to manually open the app and wait a second or two for it to update to check if I have any new mail.

-I wish I could manually override the way some emails are grouped. For example, I ordered a MacBook charger for my mom. eBay sent me an order confirmation under its own contact. I would have liked the option to manually group that specific email with my moms contact to keep it all relevant correspondence in one place.

-It would be nice to have the option to see a small badge near each contact. It would show the number of emails that are contained within in that contact. Just for a quick, clearer overview of my inbox.
