Reverse email lookup
Find out who is behind a work email address: their name, role and company. We show a person only when we can tell it's really them.
Looking up people one address at a time? GEOboom finds the pages AI answers cite, finds the right person at each one, and runs the outreach to get you mentioned, with the mailboxes included.
See how it worksHow we decide it's them
They work there now
The profile has a current job at the address's company, by its website or its name. A past job, or a company that only links to that domain, doesn't count.
The name fits the address
jane.doe@ or jdoe@ is a strong match for Jane Doe. jane@ is only a possible one: any Jane at the company would fit, and we say so.
Otherwise, nothing
A profile that fails either test isn't shown. Writing to the wrong person by name is worse than not knowing.
Questions
How does the reverse email lookup work?
Enter a work email address. We look for the professional profile that goes with it, then check the profile against the address: that the person works at the address's company now, and that their name matches what the address says. Only a profile that passes is shown, with how strong the match is.
Why won't it look up Gmail or other personal addresses?
A personal address belongs to a private person, and finding who is behind one is a people-search, not a business tool. We look up work addresses only, where the question is who you're dealing with at a company. For a personal address, the email itself, a reply, or a call is the honest way to find out.
How accurate is it?
Lookups by address are often loose: in our tests, a data provider matched a short first-name address to a different person at the same company, and one address to someone at a different company altogether. So we show a profile only when the company and the name both fit, call a first-name-only address a possible match rather than a sure one, and show nothing rather than a guess.
Is it free?
Yes. You sign in with your email, using a code rather than a password, and get 5 lookups a day. Each lookup costs us money, and the sign-in keeps bots from running it.
Does the person know I looked them up?
No. Nothing is sent to the address, and the lookup reads professional profile data, not their mailbox. We don't keep your searches beyond a day, to answer a repeat lookup without paying for it twice.
What can I use it for?
Checking who wrote to you before you reply, preparing for a call with someone you only have an address for, or making sure an address on your outreach list belongs to the person you mean to write to.
