Find Anyone's Business Email

How to find someone's email address (the reliable way)

Here's some good news. Companies are boringly predictable with email addresses. Once a company picks a naming convention, it applies to every employee. So finding one person's email is really a two-step problem. Step one: figure out the company's format. Step two: plug in your prospect's name. This tool handles step two instantly. It generates every plausible permutation, ordered by the formats companies actually use. Across millions of verified corporate addresses, first.last@company.com alone covers roughly a third of all businesses. first@ dominates startups. And flast@ (first initial + last name) shows up most at large enterprises.

What about step one? Hunt for a single known address anywhere on the company's website. A press contact. A blog author byline. A support reply. A conference speaker listing. If anyone at the company uses first.last, your prospect almost certainly does too. LinkedIn, this permutation list, and one verification check will find most B2B addresses. No expensive database seat required.

Always verify before you send

Here's what most "email finder" tools won't tell you. Guessing is free. Sending to a wrong guess is not. When an email bounces, the receiving server logs it. Mailbox providers treat your bounce rate as a core spam signal. Cross the 2% threshold and Gmail and Outlook start routing your messages to spam. Even the perfectly legitimate ones. So never blast all 12 permutations at one prospect. That's the fastest way to burn a sending domain. Do this instead. Run your top one or two candidates through an email verification service — many offer free checks. Confirm a deliverable status. Only then add the address to your outreach sequence.

Other tricks for confirming an address

• Check the company's MX setup. Does the domain run on Google Workspace? Start composing to the address from Gmail. If a profile photo appears, the mailbox almost certainly exists.
• Search the address in quotes. Google "jane.cooper@acme.com" with the quotes. The address often turns up in PDFs, event pages, or GitHub commits. Instant confirmation.
• Look at the personal-name edge cases. Hyphenated surnames. Middle names. Nicknames like Bob vs. Robert. These cause most false bounces. Try the name variant the person uses publicly on LinkedIn.
• Mind catch-all domains.Some companies accept mail to any address at their domain. Verification tools then return "risky" instead of "valid." Treat those with caution. Lean on the most common format.
