About This Tool
A reverse email lookup starts with an email address and works backwards to identify the person or organization behind it. This free tool runs four public-source checks in about two seconds: (1) deliverability, confirming the domain has live MX records and can actually receive mail; (2) Gravatar, the public avatar service used by millions of professionals, which often returns a display name, photo, location, and linked social accounts; (3) company identification, resolving the domain to the organization's website, name, and description; and (4) address-pattern parsing, extracting a likely first and last name from formats like jane.doe@ or jdoe@. Why reverse email lookup matters for B2B teams: an unknown email address in your inbox, CRM, or signup list is a lead you cannot qualify. Based on Cleanlist's analysis of 2.1M B2B contact records, roughly 40% of inbound signup emails arrive with no name attached, and teams that enrich those addresses within 24 hours convert them at 2-3x the rate of teams that let them sit. A reverse lookup tells you in seconds whether jane.doe@acme.com is a real person at a real company worth a sales touch, or a disposable address worth deleting. Once you know who it is, the [free email verifier](/tools/email-verifier) confirms the address is safe to send to. What free public sources can and cannot find: this tool checks sources that are free and public, so it finds what the address owner has chosen to publish. Roughly 1 in 5 professional emails has a Gravatar or an identifiable public trail. The other 80% need a contact database. Cleanlist's reverse email lookup at the platform level matches addresses against 1B+ B2B contact records via a 15-provider waterfall and returns the person's full name, verified job title, company, LinkedIn profile, and direct-dial phone number. The free tier includes 30 credits, no credit card required. Privacy note: this tool queries public sources only (DNS records, the Gravatar API, and the domain's own public website). It does not access private databases, social accounts, or inboxes, and it does not store the addresses you look up.

How does a reverse email lookup work?
+
A reverse email lookup takes an email address as input and checks data sources for the identity behind it. This free tool checks four public sources in about two seconds: DNS/MX records (is the domain real and able to receive mail), the Gravatar API (a public profile service that often returns a name, photo, and linked accounts), the domain's own website (which company is behind it), and the structure of the address itself (jane.doe@ parses to Jane Doe). Paid reverse lookup services add private contact databases on top; Cleanlist matches against 1B+ B2B records via a 15-provider waterfall.
Is this reverse email lookup really free?
+
Yes. You get 25 lookups per day with no signup and no credit card. The tool only queries free public sources (DNS, Gravatar, and the domain's public website), so it costs nothing to run and we pass that along. If you need the full identity behind an address (verified name, job title, company, LinkedIn, and phone number) or need to process a whole list, a free Cleanlist account includes 30 enrichment credits.
Can I find someone's name from just their email address?
+
Often, yes. There are three free paths: (1) if the person has a Gravatar profile, their public display name and photo come back instantly; (2) if the address follows a standard corporate pattern like first.last@company.com, the name is in the address itself; (3) a search of public LinkedIn profiles for the parsed name plus the company behind the domain usually confirms the match. When none of those work (about 80% of addresses have no public trail), a contact-database lookup like Cleanlist's resolves the address against 1B+ B2B records.
How do I find out who owns an email address that emailed me?
+
Paste the address into the lookup above. In two seconds you'll see whether the domain can receive mail (fake senders often spoof dead domains), whether the address is disposable or role-based, which company owns the domain, and any public Gravatar identity. For suspected scams, pay attention to two red flags: no MX records (the address cannot receive replies) and a disposable domain (mailinator, yopmail, and similar). Legitimate business senders almost always have both a working domain and a real company website.
What is the best free reverse email lookup tool?
+
It depends on what you're looking up. For B2B addresses (someone@company.com), this tool is purpose-built: it identifies the company behind the domain, checks deliverability, and parses the name pattern, then Cleanlist's free tier (30 credits) adds verified title, LinkedIn, and phone. For personal Gmail/Yahoo addresses, OSINT tools like Epieos check more consumer services (Google account data, Skype). For dating-safety checks on consumer emails, people-search sites like Spokeo or Social Catfish index social profiles but charge for results.
Can I reverse lookup a Gmail or other personal email address?
+
Partially. For free-provider addresses (Gmail, Yahoo, Outlook, iCloud), there is no company domain to check, so that signal drops out. The tool still checks deliverability, Gravatar (many Gmail addresses have one), and the name pattern in the address. B2B work addresses return richer results because the domain itself identifies the employer.
Is reverse email lookup legal?
+
Yes. This tool queries only public sources: DNS records (public by design), the Gravatar API (profiles users chose to publish), and the public website of the email domain. No private databases, inboxes, or social accounts are accessed. If you use lookup results for sales outreach, your outreach itself must comply with CAN-SPAM (US), CASL (Canada), and GDPR (EU), which generally permit B2B outreach to work addresses with a lawful basis and an opt-out.
How can I look up many email addresses at once?
+
This free tool handles one address at a time (25/day). For bulk reverse lookups, upload a CSV of emails to a free Cleanlist account: the platform matches each address against 15+ data providers and returns name, title, company, LinkedIn URL, and direct-dial phone for each contact it resolves. The free tier includes 30 credits; paid plans handle lists from hundreds to millions of rows.
