# How to find local business owners' emails from public records

> Which public records name a local business's owner, why they rarely give an email, and how to get from a named owner to a checked email address.

By Wade, Duckrow's research desk (a house pen name). Published 2026-10-21, updated 2026-10-21.

Public records name owners more often than they give emails. State business registries list officers and registered agents, licence boards list licence holders, and health and trucking registries list officials. Use them to get the owner's name, then find the email on the business's own website, or build it from the name and domain and check it before you send.

## Which public records name a business owner?
Several kinds of record name a person. What each one names differs, so read the role before you write to anyone.

| Record | Who it names | Email in the record? |
| --- | --- | --- |
| State business registry (Secretary of State) | Officers, directors, members or a registered agent, depending on the state | Rarely |
| Licence boards (contractors, electricians, plumbers, salons) | The licence holder or the person responsible for the licence | Sometimes, in a few datasets |
| NPPES NPI Registry (US health care) | The authorized official of a practice | No |
| US DOT motor carrier census (FMCSA) | Up to two company officers | An email field, where the carrier gave one |
| City business licence lists | Some cities list owners; many list only the business | Rarely |

A registered agent is often the owner at a small firm, and often a paid agent company at a larger one. Skip agent companies. They forward legal papers and buy nothing.

## Where do you get the email once you have a name?
Start with the business's own website. Contact, about and team pages often print the owner's address, or a general one like info@. If the site names no address for the person, build the likely ones from their name and the website's domain, then check each one with an email verifier before you use it.

1. Take the domain from the business's website. A free address like gmail.com tells you nothing.
2. Try the common shapes: first@, first.last@, firstlast@, flast@.
3. Check each guess. Keep only addresses the checker confirms.
4. Keep the source of the name beside the email, so you can say where it came from.

## Can you email an owner you found in a public record?
In the US, the CAN-SPAM Act applies to business email too: the FTC says "the law makes no exception for business-to-business email". Commercial messages need an honest sender and subject, a postal address and a working opt-out, and you must honour an opt-out within 10 business days.

In Canada, CASL needs consent. One form of implied consent covers an address the person has conspicuously published, when the publication doesn't say they refuse unsolicited messages and your message is relevant to their business role. An address in a registry filing is a different thing from an address printed on their own website, so keep a note of where each one came from. This is general information; check with a lawyer for your own case.

## How does Duckrow find local owners and their emails?
Local businesses fills a table with businesses of a kind in a place, from Google Maps listings with Overture Maps open data as the fallback, for 1 credit a business added. Then Find the right people names the owner, or the roles you pick, for 2 credits a person found.

- It reads the business's own team, about and contact pages, and respects robots.txt.
- It asks free public registries that cover the business: the New York, Colorado, Oregon, Connecticut and Pennsylvania business registries; licence boards in Texas, Washington, Oregon, Connecticut and New York City; Chicago's business owners list; NPPES for health care; the FMCSA carrier census; and Toronto and Winnipeg licence lists.
- Each person is marked Verified when two kinds of source name them, or Likely when one does, with the sources listed.
- When the site prints the person's email, it fills an email column. The Find owner emails option runs Find work email on the owner's name and the website, for 6 credits per checked email, only when one is found.

## How often does it find the owner?
For a minority of businesses. In Duckrow's own test tables, owners were named for 4 to 8 of every 33 businesses. A person is named only when the website or a registry names them, and you pay only for the people found.

Registry coverage is uneven. Outside the states and cities above, Duckrow reads the business's website only. Alberta publishes no free registry with owner names, so Calgary businesses rely on their websites.

## Questions
### Do state registries list owners' email addresses?
Rarely. They list officers, members or a registered agent. Use the name to look for the email on the business's website or to build one and check it.

### Is the registered agent the owner?
At a small business it often is. At a larger one it is often a paid agent company, which Duckrow skips.

### What does Duckrow charge to find an owner?
2 credits per person found, and 6 credits per checked email found. Nothing when nothing is found.

### Which places do Duckrow's registries cover?
Business registries in New York, Colorado, Oregon, Connecticut and Pennsylvania, licence boards in Texas, Washington, Oregon, Connecticut and New York City, Chicago, US health care and trucking nationally, and Toronto and Winnipeg.
