## Description

Open your inbox and all you see is a list of sender names. Which emails are from companies? Which are personal? Which are official government notices? It's hard to tell at a glance.

Email Sender Info adds a small icon next to every sender, turning your inbox into something you can scan instantly — like Caller ID, but for email.

■ What it shows

🏢 Company & service mail
Displays the brand favicon of the sender's domain. Mail from <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/c9c28e186e7bb08c3757b51a0620aca9de31e89fd32e9cce724bccaa1cc0ff2f/http%3A//tesla.com" rel="nofollow">tesla.com</a> gets the Tesla logo; mail from <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/18292d9c1899dd2b453ea9e3c1375587569f07a1d91694af6d865f8eab086cdb/http%3A//github.com" rel="nofollow">github.com</a> gets the GitHub icon. You can tell which company or service an email came from without opening it.

👤 Personal mail
Recognizes about 4,800 free and consumer email providers — Gmail, Outlook, Yahoo, iCloud, Proton, Naver, Daum, Kakao, Nate, and more — and adds a small "person" badge alongside the favicon. Company mail and personal accounts become instantly distinguishable.

🇰🇷 Republic of Korea government mail
Mail from <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/95943a944fef5696983bf8fa90991a828bd437d5629603fac41d575fa485be41/http%3A//korea.kr" rel="nofollow">korea.kr</a>, <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/64f390c606de3f24cd02a788c2ae52d8f36cdc41e259813d0c12a4b702320d0b/http%3A//go.kr" rel="nofollow">go.kr</a>, and <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/1101514b723d5b2a910a50bdbe00d31b9319d9f885b4c3c96228aec9d2daffa3/http%3A//mil.kr" rel="nofollow">mil.kr</a> domains shows the official Government of the Republic of Korea emblem, making official government mail easy to recognize — which also helps spot messages impersonating public institutions.

🇺🇸 United States government mail
Mail from .gov and .mil domains gets a US government badge.

· Professionals and freelancers juggling work and personal mail

■ Privacy

Email Sender Info does not collect your data.

· It does not read email bodies, attachments, or recipient lists — only the sender name and address already shown on screen.
· No third-party analytics, no tracking, no remote server.
· Favicons are fetched from Google's public favicon service; nothing else is sent anywhere.

■ How to use

Just install and open a supported mail service. No setup, no login — sender icons appear automatically.
