Free Reverse Email Lookup

An email address lookup (also called an email lookup) is the reverse of finding someone's email: you start with the address and identify who it belongs to. A lookup checks whether the address can receive mail, which company owns the domain, and any public profile tied to it, then parses a likely name from the address. This free reverse email lookup runs all of those checks in about two seconds. For the full verified identity, name, title, company, LinkedIn, and phone, Cleanlist matches the address against 1B+ B2B contact records.

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.

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.

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.

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.

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.

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.

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.

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.
