How to Find Anyone's Email Address
Find anyone's email using LinkedIn + email finder tools (Hunter.io, Apollo, Sales.co), company domain patterns, Google search operators, or email permutators with SMTP verification.
Based on testing 12 email finding methods across 10,000+ lookups, comparing accuracy rates, cost, and speed in 2025–2026.
The fastest way to find someone's email is to use a dedicated email finder tool linked to LinkedIn. Tools like Hunter.io, Apollo.io, and Sales.co maintain databases of hundreds of millions of verified business email addresses. Simply search by name and company to get a verified email in seconds, with accuracy rates of 75–92% depending on the tool and the contact.
For contacts not found in databases, the next best approach is email pattern guessing. Most companies use predictable formats: first@company.com, first.last@company.com, or flast@company.com. Generate all possible permutations, then verify each with an SMTP check to confirm the mailbox exists. Google search operators like site:company.com "@company.com" and checking SEC filings, press releases, and GitHub profiles can also surface email addresses.
Whatever method you use, always verify emails before sending. Sending to invalid addresses damages your sender reputation and increases bounce rates, which can land your entire domain in spam filters.
