How do I find someone's business email address?

Start with where the address is already public

Before you guess, look. Company websites often list a contact page, a team page or a press page with direct addresses. Small businesses frequently put the owner's address in the footer. Conference speaker pages, podcast show notes, GitHub profiles and local business directories sometimes include one too.

A named person's address is better than a generic one. Writing to info@ means someone may or may not read it. Writing to priya@ means a person did. If the only address you can find is generic, use it for a first try and look for the owner's name on the About page.

Work out the pattern

Most companies pick one format and use it for everyone. If you can find a single confirmed address at the company, you can usually deduce the rest.

priya@brightwater.example (first)
priya.raman@brightwater.example (first.last)
praman@brightwater.example (first initial plus last)
pr@brightwater.example (initials, rarer)

Say you know a colleague, Marcus Hale, is marcus.hale@brightwater.example. Then the owner, Priya Raman, is almost certainly priya.raman@brightwater.example. Small companies are the least predictable, since the founder may use a first-name-only address while later hires follow a different format.

Confirm it before you send

A guessed address that does not exist bounces, and a high bounce rate hurts how mailbox providers treat you. There are three honest ways to confirm:

1. Use a lookup or checking tool that tests whether the mailbox exists. They are not perfect, and some servers accept everything and bounce later.
2. Send one short, genuinely useful email to your best guess. If it bounces, try the next pattern.
3. Call the company and ask who handles the topic, then ask for the best way to reach them.

Rocketship does not run its own verification step before sending, so if you bring your own list, check it first. See <A href="/press/cold-email-bounce-rate">cold email bounce rate</A> for what a healthy number looks like.

Do it in bulk without losing a week

By hand, plan on about three to five minutes per person once you include finding the right name. A hundred people is five to eight hours. Past a few hundred, a data tool is the sensible choice. Rocketship can find people by name from a description of your buyer, using enrichment credits (Launch includes 100 a month, Frontier 250), and it reads Apollo and HubSpot exports directly if you already have a list. Importing your own contacts is free.

Stay on the right side of the rules

Finding a work email is legal in the US. What you do with it is what the rules cover: commercial email must follow CAN-SPAM, and in the EU and UK, privacy law applies to personal data, including work addresses that name a person. Read <A href="/answers/is-cold-email-legal">is cold email legal?</A> for the plain-language version. It is general information, not legal advice.

A short checklist

1. Confirm the person's name and role.
2. Look for a published address on the website and public profiles.
3. Identify the company's format from one known address.
4. Check the guess with a tool or a careful single send.
5. Record where you found it, so you can remove the person if asked.
