Drag

The most noticeable improvement has been opening my mail and knowing instantly what's going on at a glance, which frees resources in my mind (peace of mind, what a treasure!)

Besides that, I use the GTD method to organize my tasks. Every day I process my inbox following GTD's algorithm:
1. If something takes less than 2 minutes, I do it and archive the mail.
2. If I can delegate it, I do it and either archive the mail or put it in Doing, to follow it up.
3. If I want to do it, I move it to "Doing".

This is an improvement over having just a list of tasks outside of my mail, because a lot of mails don't need to become tasks in an external app, and can be managed more easily with Drag, which reduces significantly the overhead of having to create tasks and follow up somewhere else, besides avoiding having to switch between between apps (from tasks to mail, etc), simplifying my workflow and increasing my productivity.

I haven't found any opportunity cost so far in using Drag. I miss some functionalities, though. Mainly, I miss a way to defer mails I don't want to pay attention to now until a later date.

This functionality already exists in Google's Inbox Mail App and I need it because it's one of the steps of the GTD's algorithm I mentioned before.

Great user interface and fairly intuitive tool. Looks really clean and well built. Quick load times.

I like to filter and archive emails A LOT. Annoyingly if you archive an email it disappears from the Kanban if you haven't asked support to switch this feature off. This was not clear and frustrated me, hence the switch to something helse.

Before Drag, my inbox was a mess. I would not have any proper method of keeping track of emails and it got to the point where things fell through the cracks which amounted to lost business. What I like most about Drag is that it resembles kanban boards that I'm familiar with in the software space and it gives me a good means to make sure that emails don't get forgotten about.

I also like how it seamlessly integrates into your email using the Chrome extension and doesn't require any additional onboarding steps. Usually, the problem with bringing on new software is that it is too laborious to integrate it into your daily routine. That's not the case with Drag. With the toggle of a button, you can switch it on and off at your discretion, as well.

One of my email inboxes has over 11,000 emails. I found that integrating Drag with that particular email really slowed things down when it came to website speed. This is more mismanagement on my part and it's my goal to reduce the number of emails I have in that inbox so that I can actually use Drag.

In addition, Drag doesn't currently allow you to customize the labels on the kanban board or add any additional steps. To my understanding, this is a feature that they hope to launch in the future, however.
