Free Guide
You have an email address. You want a name, role, company, and LinkedIn — without paying. Here are eight methods, ranked by accuracy and effort. The first three solve most cases for free.

jane.doe@acme.com → Jane Doe at Acme. Combine the decoded username with LinkedIn's company-employee search. Works for the majority of business addresses in under thirty seconds.
"jane.doe@acme.com" in quotes, then add site:linkedin.com, site:github.com, site:twitter.com. Many people publish their address on personal sites, GitHub READMEs, conference bios, and old CVs.
Free. Tells you which services the email is registered with. Useful for confirming a real person (a SaaS founder email registered on Stripe + GitHub + AWS is clearly real) versus a role address or throwaway.
Free. Add the email to your phone contacts, then let LinkedIn suggest it as "People You May Know". Works for personal Gmail addresses too — many people register their LinkedIn under a personal email.
HuntMeLeads' free tier resolves business emails to verified profiles in one click. No card required, no demo required, no salesperson to talk to.
Free at whois.com. If the email is on a custom domain (@acme.com), WHOIS often lists the registrant's name, organization, and country — useful for solo founders and small businesses that haven't enabled WHOIS privacy.
Free. Many email addresses have a public Gravatar profile (WordPress, GitHub, Stack Overflow, and many comment systems use it). Visit en.gravatar.com/[md5-hash-of-email] or use a Gravatar lookup tool.
Free with Google Lens or TinEye. Once you find any avatar from the email (from Gravatar, breach data, or a profile photo), reverse-image search it to find every other place the same photo appears online.
No single free method is right 100% of the time. The discipline: require two independent signals before treating a match as confirmed. Email pattern + LinkedIn match = high confidence. Reverse-lookup hit + matching Gravatar = high confidence. One signal alone = a hypothesis.
Bulk needs (more than a few dozen lookups per day), API access for product use cases, CRM sync, deliverability scoring, and mobile phone numbers are paid features on every reputable provider. The free tier is designed for evaluation and personal use — not for running an outbound team.
