Email Sender Icons by cloudHQ can help you identify companies or brands in your inbox. It allows you to identify a company name based on their official logo (favicon) and appear next to your email preview, instead of opening the email itself.

It’s a Chrome browser extension that runs on the cloud, and it only loads a logo (favicon) that corresponds to the sender’s email domain address.

This tool is extremely effective at helping you identify the company name, especially if the sender is a large organization.
