Very neat functionality!

I like it, thank you.

This addon is just fantastic. It allows you to recognize the sender of each mail with a quick glance, without reading his name. It makes finding emails in the sendbox and elsewhere much quicker. I think more people should hear about it and use it!

Very handy app for quickly identifying emails from different sources. Well recommended!

Great tool!

The extension works just great in my Gmail inbox.
It fetches sender's domain icons while sender's domain name appears as a tooltip while mouse hovering. Great addon.
