Email lookup: find every account linked to an address
Enter an email address and more than a hundred platforms are searched at once. Each account found appears with its picture, name and username, and you see how many breach records the address is in.
What an email lookup shows
The accounts it opens
Every platform that has an account for the address comes back as a card: the profile’s picture, banner, display name and username, with follower counts where the platform keeps them.
Its breach exposure
The same search counts the breach records the address appears in, and how many separate breaches they came from, so you know whether it has been caught up in leaks before.
Nothing sent, nothing posted
The search only reads what is already there. The person who owns the address is not notified, and nothing is posted anywhere.
Why people look up an email address
An address is often the only thing you know about someone who wrote to you, sold you something or asked for access. The accounts behind it tell you whether it belongs to a real, consistent person.
- Check your own footprintSee which accounts your address opens and what a stranger could learn from it.
- Verify before you pay or replyConfirm that a seller, landlord, recruiter or new client is the person their emails claim.
- Investigate fraud and phishingPut a profile to the address behind a scam message before you report or block it.
- OSINT researchStart an investigation from an address, as described in the email OSINT guide.

Questions
How do I find the accounts linked to an email address?
Type the address into the box and press Search. More than a hundred platforms are checked at once, and each account found appears as a card with the profile’s picture, name and username as soon as its platform answers.
Is this email lookup free?
Yes. There is no account to create and nothing to pay. Each visitor gets five checks a day, shared with Seer’s own free check, and they come back the next day.
Will the person know I looked up their email?
No. Nothing is sent to the address you search, and no platform tells its user that someone looked. Nothing is posted and no one is contacted.
What does a result show?
The top of each profile found: its picture, banner, display name, username and follower counts where the platform has them. Some platforms only confirm an account exists, and those appear as a short line. The address’s breach records are counted too.
Does “no accounts found” mean the address is unused?
No. Some platforms keep their members out of sight, many accounts sit on platforms no search covers, and people often sign up with a different address. A clean result means none of the platforms checked showed an account, nothing more.
Which platforms are searched?
More than a hundred, from Google, Microsoft, Facebook and LinkedIn to GitHub, Spotify, Strava and Duolingo. The full list is on the Platforms page.
Is it legal to look up an email address?
Looking at what public profiles show is legal in most places. What you do with it is what the law cares about: harassment, stalking and discrimination are illegal whatever tool you used. Use a lookup to protect yourself or your organisation, or to verify someone you are about to trust.
Can I remove my email address from the results?
Yes. Seer runs the check, and its removal page at seer.to/takedown suppresses records keyed to an address you can confirm you own.
