Liking it so far—one missing feature

I purchased the pro version and I’m diving into it and so far enjoying it. I like the ability to customize the swipe actions—both the number or actions and the order.

However, my feedback and one feature missing for zero inbox is the ability to ‘swipe’ and move all contact emails to a folder. You can dive into an contacts list of emails and swipe to move, however, moving all emails is a contact is not an option.

I need this as I file my emails according to project/client and some how I thought this intuitive function would be there ready for me to use. But alas, it is not. Can this be added? I certainly will update my rating to five stars for this!

Finally... Personal Best

OK, I have tried every email client available. I’m pretty sure that’s not even hyperbole. For the past few years I have been ping-ponging back-and-forth between Spark and Airmail, with Outlook thrown in. I used Unibox about five years ago (MOL) when they were just starting out. It had some interesting abilities as it groups emails by contact, but it also had too many features that were missing, especially mass delete. No longer.

This is the best client for someone who uses email primarily for personal or small business reasons. All the other email client are bloated with features designed for teams. When I worked in big(ger) business, there was so much email on which I was simply copied and the daily deluge was ridiculous. If that is your email life, a client that focuses on sorting email by conversation will probably be more relevant.

Unibox works very well for a small-business, self-employed person. If you are looking for a client to keep your personal email separate from the morass of business emails (which is a very smart idea), this is the ONE to use.

And the UI is gorgeous, the onboard help cleverly done, and the desktop version is free. The iOS price is right (I am happy to pay a small one-time fee to support development like this. Heck, I’d even pay $4.99 per year.) Congratulations, Unibox.

The best way to handle your e-mail.

I had a brilliant idea, searched the web, and found this app which already does what I wanted to do: Sort your mailbox in a way that’s actually useful - something I every other mail client seems to fail to do. It’s missing keyboard commands and doesn’t make the best use of my iPad Pro 11” display, and it needs an update. I hope it gets one soon. I just bought the Pro upgrade. I’d be more than willing to pay a subscription in the area of $6 / year rather than $6 once if it was updated regularly to fix any bugs, support new devices and versions of iOS, etc. It doesn’t need many more features! It’s great.
