Feladói információ Email Sender Info szerző: 박정섭

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 tesla.com gets the Tesla logo; mail from github.com 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 korea.kr, go.kr, and mil.kr 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.

· No third-party analytics, no tracking, no remote server.
· Favicons are fetched from Google's public favicon service; nothing else is sent anywhere.
