Reverse Email Lookup Tools by Data Type
Every reverse email lookup tool returns a different slice of data. We tested 8 tools across four data types (name, social, breach, consumer records), documented what each actually returns, and built a matcher to pick the right one for your question.
lightbulbKey takeaways
- arrow_rightNo single tool returns every data type. Route each email through 2-3 tools based on what you need: name (B2B tools), social (EmailRep.io), breach (HaveIBeenPwned), consumer records (ThatsThem or paid people-search).
- arrow_rightFor B2B professional context, Mailsfinder gives the largest free daily quota (100/day, 3,000/mo) with API access on the free tier.
- arrow_rightEmailRep.io is unique for social-profile mapping. It's how fraud teams verify a real digital footprint exists behind an unfamiliar email.
- arrow_rightHaveIBeenPwned is the authoritative source for data-breach history at $3.95/month for API access. Every trust-and-safety team we spoke to considers it non-negotiable.
- arrow_rightFor US consumer records, ThatsThem is the strongest free option. Paid alternatives (BeenVerified, Spokeo, TruthFinder) start around $25-$30/month and add deeper records but hit the same public-record source data.
- arrow_rightAll 8 tools listed have APIs. Combined free tiers give you well over 5,000 lookups per month if you split usage by data type. See our free-only reverse lookup guide for a focused breakdown.

1. Mailsfinder
Name + company (B2B)
Mailsfinder returns first name, last name, company, and job-title inference when the input email is in the B2B database. It's the cheapest way to get name-plus-company on a professional email, with 100 free credits per day forever and $9.99/month unlocking 300,000 credits. API access is included on every plan including free.
"100 free credits per day means we route the majority of our enrichment through Mailsfinder without paying anything."

2. EmailRep.io
Social + reputation
EmailRep.io maps an email to LinkedIn, GitHub, Twitter, Gravatar, Spotify, Airbnb, and 50-plus other services, and returns a 0-100 reputation score. Unlimited free manual lookups on the website; API access is free on request. It's the fastest way to check whether an unfamiliar email belongs to a real person with a public digital footprint.
"Every fraud analyst on our team has emailrep.io bookmarked. Faster than any paid enrichment vendor for the specific 'is this a real person' question."
-- Trust and safety analyst via product feedback
3. Have I Been Pwned
Data breach history
HaveIBeenPwned is the definitive free source for data-breach history on an email. It uses the actual breach dumps, which makes it essentially 100 percent accurate. Manual lookups are unlimited on the website; structured API access is $3.95/month, one of the cheapest per-request enrichment services in existence.
"Every account signup at our company runs through HIBP for risk scoring. Cheapest fraud signal money can buy."
-- Fraud engineer via product feedback
4. ThatsThem
US consumer records
ThatsThem is a free consumer-grade people-search focused on the United States. Enter an email and it returns name, physical address, phone number, and household demographics when the address matches public records. Coverage is strongest for older personal emails tied to home addresses. Paid alternatives (BeenVerified, Spokeo, TruthFinder) start around $25-$30/month and hit the same source data with deeper history.
"Only tool that consistently returns anything on personal Gmail. Great for one-off customer support triage."
-- Customer support lead via product feedback
5. Hunter Email Verifier
Name + source URL
Hunter Email Verifier returns name plus source URLs where the address was originally found (LinkedIn profile, GitHub commit, blog author page). That source-URL field is unusually useful for verifying who owns a professional email. Free tier is 25 verifications per month, then $49/month for 2,000 credits. API access is included on every tier.
"Source URLs field is what keeps us using Hunter over cheaper competitors. It tells us where the email first appeared publicly."
-- Growth marketer via G2
6. Snov.io
B2B lookup + campaigns
Snov.io bundles B2B lookup with drip email campaigns, which makes it useful when you need to identify a professional email owner and then reach out. Free tier is 50 credits per month plus 100 email recipients for outreach. On lookup, Snov returns name, company, and verification status.
"Free tier renews monthly, so we use it for weekly enrichment plus small campaigns. Basically a free cold email sender if you're small."
-- Solo founder via G2
7. Anymailfinder
Pay-only-for-verified B2B
Anymailfinder offers a "pay only for verified emails" credit model that makes pricing predictable. Free tier is a 7-day trial with 100 credits, then paid plans start at $14/month. On lookup, returns name, company, and 97%+ deliverability guarantee. Middle of the pack on B2B but cheapest paid entry point.
"Verified-only credit model made pricing predictable. We stopped hunting for phantom emails and just paid for what actually landed."
-- Outbound consultant via G2
8. Reoon Email Verifier
Deliverability check
Reoon covers the deliverability slice of reverse lookup: is this email real and safe to send to? Returns valid, invalid, catch-all, disposable, or role-account flags. 20 free credits per day forever, plus API on the free tier. Use it as a sanity check alongside Mailsfinder or Hunter to confirm an enriched email is still deliverable.
"Cheapest verifier that actually works. Run the daily 20 as a sanity gate on any email we've enriched from other tools."
-- Agency owner via G2
