Ratings and reviews

The best mail app for personal mail accounts. Personal-focused threads are awesome. The only caviat is UI (still). I wonder, what is the REAL reason to use 20 years old chat system UI approach?! Really? Why I need to make extra click to see the email in full size? Why "chat"-like UI doesn't scale properly on large screens? Folks, PLEASE, change it!

I am new to Spike and enjoying its many features. I absolutely love having fewer emails and more organization. It's efficient to be able to directly access conversations in message form. I'm still trying to figure out how to manage multiple emails under one umbrella but, I'm sure I'll figure it out. Highly recommend this app, especially if you're looking for more organization.

Truly the best email client I've tried, and it's part of my daily workflow across mobile and desktop. It really makes life smoother. (Update 3 years later) Spike is still my go-to for keeping track of multiple email accounts, and it's getting better all the time. There's still some room for improvement, but I'm really happy with the way Spike is headed.
