Do you use gmail as your work email client?

I tried Superhuman and its good but lately I've been using Spark Email (with TickTick)

I use Missive

I use Gmail and Outlook. I like both of them. First of all, they are simple and convenient. Also, I got used to them. And it is possible to use different email software like Email Detail Search, for example, that hallows to find the necessary letters among the old archived filed. I should say, such tools really help to ease the work.
