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.

Great concept, no updates.

Still like the concept and wish development on the app would continue, but minus the once a year update when iOS changes, there is nothing going on with this app from the developer. I wish another developer would take the concept and expand to make it a true email powerhouse.

Still love the Unibox concept but the app just does not work well. Slow to update, emails not syncing, infrequent developer updates to the app and notifications that simply don’t work. I don’t use anymore but keep it around just hoping someday the updates will fix most of the issues and get push notifications working. If you are coming from the Mac app that also has many issues, I would save yourself $5 and walk away.

Version 1.1 update:
Had deleted the previous version as the updating just did not work for me. I still use OSX version and love the concept. I want to like the iOS version. The search function is much improved and also spotlight search is a great addition. For this to be my everyday email client, and I really want it to be, I need them to add an option for push notifications. I simply have to many emails that need to have attention quickly. I will keep using it, but still some bugs to work out. Overall good improvement from V1. Hoping for more updates with a quicker timeline than 1 per 8-9 months.
