School database in Washington, D.C.

29 at the time this page was generated, with the most in Washington, D.C. (29). The count is queried from our index whenever the page is rebuilt (at most daily), so it moves as we find and re-check businesses.

Businesses are found on Google Maps by category and area, deduplicated, and checked: whether they have a website, whether that website is really theirs (a Facebook page or a directory listing does not count), and — where there is a site — what it says. Emails are taken from the business's own pages, never guessed from a pattern.

Yes, where the business publishes one on its own website. We read sites continuously; emails appear as each site is read, graded from a named person's address down to a generic inbox.

Not from this page — names are shown here because they are already public on Google Maps; phone numbers, emails and addresses are what you unlock in Mantis, a business at a time or in bulk, and export from there. Free to start: every account gets 500 credits once.

These are businesses, contacted at their published business details. B2B outreach is generally allowed, but the rules differ by country — the UK and EU expect a legitimate-interest basis and an easy opt-out, India's DPDP Act covers personal data. Mantis adds unsubscribe handling to email campaigns; check the rules for the countries you sell into.

A bought list is a snapshot — often years old, priced per record, and blind to businesses without a website. This one is built from live map data and our own website reads, and Mantis re-checks a business when you use it, so you are not paying for closed shops and dead inboxes.
