A work email address is the key to your outreach — and the easiest place to break trust or the rules. The legitimate ways to find one are public, verifiable, and used individually: the company website, a known email pattern confirmed by a checker, and finder tools that verify before you spend a message. This page gives you the method-by-method table, the accuracy notes, and the permission/compliance box to stay inside the lines.
The methods, ranked by legitimacy and accuracy
Here is the asset:
| Method | How it works | Accuracy | Legitimacy |
|---|---|---|---|
| Company website / contact page | The company publishes a sales or info address; the pattern is usually first.last@company.com | High when published | High — public, intentional |
| Email-pattern + verifier | Guess the pattern from one known address, then run it through a verifier that checks the mailbox without sending | Medium, then verified | High — you verify before sending |
| Finder tool (a B2B email finder) | The tool resolves a name to a business email and flags confidence | Medium–high | Medium — use tools that source from public/consented data, not scraped |
| LinkedIn + company-site research | Confirm the right person by title, then use a verifiable pattern | High for the person, medium for the address | High — public research, not scraping |
| Scraped list from a broker | A bulk list of addresses whose origin is unknown | Low, full of dead and wrong addresses | Low — a permission and compliance problem |
| Guessing random addresses until one lands | Send to firstname@, lastname@, info@, etc. until something sticks | Low | Low — looks spammy and breaks consent |
The permission/compliance box. Sending commercial email is regulated (CAN-SPAM in the US, GDPR in the EU; this is not legal advice). The safe operating rules: only reach people in a business context, at a business address, about something relevant; identify yourself honestly; make it easy to stop; never buy a scraped list or blast a mass send. One relevant, individual message to a real person is the difference between outreach and spam.
The order that keeps you legit
Work down from most to least legitimate, and verify before you send: check the website, confirm the person, build the pattern from a real example, run a verifier, then send one relevant message. Every method gets one test against the compliance box: would this look fine if the recipient or a regulator saw how I got it? If not, don't.
Why the address matters less than the ask
An accurate address is step one; the message is step two. A perfectly-found address with a generic pitch is wasted — your cadence and sequence do the converting, and the trigger makes the timing right. Find the address legitimately, then make the message worth opening.

You can reach the person. The reason you should reach them now is the next piece — sales triggers: the buying signals that tell you when to reach out.
