Where it was found. Every email notes where it was published: the company’s contact page, about page, homepage or a public listing.

Real businesses, public data. These are public business contacts. Listings marked OSM come from OpenStreetMap, © OpenStreetMap contributors (ODbL). See all 25 rows of a real list.

Rows 03 and 06? Flagged, not deleted. A Gmail address or a domain that doesn’t match the website gets marked so you make the call, not us.

02 Method

Five steps per list. No shortcuts in between.

Each list is researched for your spec, not pulled from a database someone else built for everyone. That’s slower, and it’s the point.

Spec

You tell us who you sell to and what a good row looks like.

industry / company type
locations
must-haves & exclusions

Find

We search public sources for companies that fit.

public business listings
map & directory data
the company’s own site

Record

Each row gets the business details and where they came from.

company, website, location
category, business email
source of each row

Check

Every email is tested before it reaches you.

syntax check
mail server (MX) lookup
free-mail & domain-match flags

Deliver

A tidy file with every check visible, ready to import.

■ What MX means

An MX check confirms the email’s domain is set up to receive mail. It doesn’t prove a specific inbox exists, so we never call a list “guaranteed deliverable.” We tell you exactly which checks each row passed.

03 Fields

Every column, and what’s behind it.

Standard columns on every list. Need something else, like a phone number or a website note? Add it to your spec.

company	The business name as the company presents it on its own website or listing.
website	The company’s main site, checked to load.
location	City and state, plus street address when it’s publicly listed.
category	What the business does, mapped to the categories in your spec.
business_email	An email the company published itself. Never guessed from a name pattern.
email_type	Role address (info@, office@) or a named/other address, so you can segment.
found_at	The page or listing where we found the email.
syntax · mx	Whether the address is well-formed and its domain has a mail server.
free_mail · domain_match	Flags for Gmail-style addresses and emails on a different domain than the website.
source · checked_on	Where the row came from, and the date we checked it.

04 Who it’s for

For people who sell to businesses, not databases.

If you know exactly who you want to reach but not where to find them, a spec-built list is the shortest path. A few examples of what that spec can look like:

Agencies

Find local businesses that need what you build: websites, ads, SEO or content.

Roofers in Denver whose sites aren’t mobile-friendly

Consultants

A focused list of firms in your niche, in the regions you serve.

Independent dental practices in Tampa Bay

Recruiters

Companies in your vertical that look like they’re hiring or growing.

B2B founders

06 Questions

Asked and answered.

Where does the data come from?

Public sources: the company’s own website, public business listings and open map data such as OpenStreetMap. The source column on each row tells you which.

Are the emails guaranteed to deliver?

No one can honestly guarantee that. Every address is syntax-checked and its domain is checked for a mail server (MX), and risky patterns are flagged. That removes the obvious bad addresses; it can’t promise a specific inbox is active.

Do you include personal emails or phone numbers?

We include business emails that companies published for people to contact them. We don’t scrape personal addresses or guess them from name patterns. Public business phone numbers can be added to your spec.

Is it OK to email these contacts?

You’re responsible for your own outreach. In the US, cold B2B email is allowed under CAN-SPAM if you identify yourself, include a physical address and honor opt-outs. Other countries have stricter rules, so check before emailing outside the US.

Can I order fewer than 500 rows?

Orders come in blocks of 500. If your spec only turns up a few hundred good rows, we’ll tell you before you pay rather than pad the list.

What if some rows are wrong?

Tell us which ones. If a row doesn’t match your spec or fails the checks we said it passed, we’ll replace it.
