Features & Capabilities

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.

■ Supported mail services

Works in both the inbox list and the open-message view.

· Gmail · Outlook (outlook.com / office.com / office365.com) · iCloud Mail · Yahoo Mail · Naver Mail · Daum Mail · Kakao Mail · Nate Mail

■ Who it's for

· Anyone who receives dozens of emails a day and needs to triage fast · Professionals and freelancers juggling work and personal mail · People who get government and institutional mail and want to catch impersonation attempts · Anyone who wants a cleaner, more readable inbox

■ 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.

Is Email Sender Info Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Email Sender Info requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Email Sender Info is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
