Growth & Ops Specialist

Now I'm in this weird place where I still have some apps in Shift and some in Chrome... it's probably worse workflow-wise than before.

Founder

It has done wonders for my productivity and efficiency. It makes me excited to start my workday and it makes working more fun.

Owner

It's a marvel of design that combines simplicity, ease-of-use, and powerful functionality into a single window with multiple panes.

Managing Partner

The only complaint I have is the LastPass extension has never worked and it's annoying when my gmail account logout and I can't just use LastPass within the app.

Project Manager

The layout and speed of Shift's platform is near perfect. I love only opening Shift on my laptop and crushing work due to the ease of bouncing between apps.

Frustrating to run into yet another poorly executed reskinned Chromium browser with secret extension -- so much potential. Unstable, crashes, resource heavy, and doesn't fully free memory when closed.

Director of Engineering

For a company where all of our tools are online, it makes a great central hub for all daily work. And the tight integration with engineering tools is nice.

UX/UI Designer and Developer

Sift is a great product that was super easy to use and pick up on.

IT Director

Uses very little resources and is quick to start after starting up your machine. Very attractive pricing makes this a good and simple platform without breaking the bank.

Digital Marketing manager 

I love having everything work related in one “space. Product is clean, functions as intended, and is a staple in my workspace.

Producer/Director

I used a lot of additional apps to manage productivity with to-do lists and it is so helpful to have everything in one window. I also love that Shift maintains Gmail's interface.

Freelance Translator

No unified calendar option, that's really something I'm missing... and actually for 99 euros a year, I feel like it's a little deceiving.

Virtual Assistant

A couple of years ago, we sent a request for Shift to integrate with Lastpass and they integrated with it pretty quickly, which is helpful with password management of all of the accounts I juggle.

Principal

I've had a great experience with Shift. I've been a lot more productive, it's easier to use when I'm doing presentations on Zoom, and it's not that expensive.

Trainer

The customer service has been spectacular, and always very responsive.

Entrepreneur

I loved the product but felt there was a significant disconnect with customer support that made it impossible to benefit from the Shift in a reliable way.

Graphic Artist

Just a few seconds can really add up over a day/month/year. It's worth EVERY single penny to me.

Shift allows me to get more done in my day and has helped me to increase my productivity. It is well thought out and so easy to use and deploy.

Pastor

I am from the old school and when I had a registration problem I had trouble getting someone to respond.

Strategic Planner

What I enjoy most about Postbox is the ability for me to customize it to my needs. I also enjoy the new features that allow me to quickly form communications and sort my incoming emails.

Filters, rules, folders, quick commands - excellent choices to help speed along message handling. Also excellent capabilities with encryption and signatures.

Software Engineer

The interface is better and can be customized with themes. The software also is more reliable than Apple's offerings, and is solid, reliable software.

Owner/Manager

All and all, I've been super pleased with it's functionality as well as it's ease of use.

founder

Its features and integration with other productivity tools make it a great choice for users who want a robust email management solution.

Account Manager

As a user with multiple projects for multiple enterprises going at the same time, I found myself missing communications or misplacing threads because of the sheer volume.

Partner

Ease of use- Grouping of emails- Ease of archive- Amazing search features.

Product Manager

Notifications are still somewhat ugly, and there is no more specific configuration about that (disable notifications for an account or certain emails, for example).

Reliable, stable Software, fast, and gets continuously improved.

Account director

When I contacted the support, I was asked to paid 8$ to get assistance. I bought a lifetime licence and now I am stuck with a broken software.

Additionally, the software integrates with popular productivity tools, such as zapier, dropbox, etc, making it easy to manage emails in the context of other tasks and projects.

I like the theme option with the software and the ability to organize accounts groups as well as folders etc easily on the fly.

Producer

But for me, it is the simplicity of it all,  that it is quick and easy, I can change the default theme with 1 click, and it only took a few minutes to set up how I wanted it.

Senior Designer

It is easy to use and has so many themes and features. So user friendly and didn't cost an arm and a leg to purchase.

Web Developer

Postbox combines the core features I need for an email app with an excellent support team.

Operations 

I've seen a lot of changes in the app and I have always been incredibly impressed with the quality of product, focus on user security, and customer service.

Ph.D. Student

Overall, I really like this e-mail app. Although, it has some cons which I explained above, it is totally worth to money.
