Amazing tool! Founder is a young and a super serious entrepreneur who is a fast mover. Betting big on Inbox Pirates!

Email preview is super important for me. I use 3 email senders but none of them give me the visuals of subject at a device level. I used to test it on my own mobiles. But this extension allows you to test the visual of subject line from multiple screen size and devices.
