Find a real, usable contact email for a list of companies. Give it a website, get back the best email it can find — scraped from the site first, then a verified fallback using UK Companies House director data and common email-naming patterns.
How the waterfall works
- Scrape the website — homepage plus contact/about/team pages, checking mailto links, JSON-LD structured data, meta tags, and deobfuscated page text (
name [at] domain [dot] comstyle included). This is the highest-confidence source, since it's a real email the company actually published. - Companies House lookup (UK companies, optional free API key) — if no email is published, look up the company's registered director name from the official public register.
- Pattern generation — from that director/contact name, generate the common corporate email conventions (
first.last@,first@,flast@, etc.). - MX verification — check the domain actually has a mail server configured before returning a pattern-guessed email, so you're not handed an address that can't possibly deliver.
Each result is labelled with a confidence level (high = scraped and looks like a real named contact, medium = scraped but generic like info@, low = pattern-guessed and MX-verified, none = nothing found) so you know exactly how much to trust it.
Input
| Field | Description |
|---|---|
companies | Array of { name, website } — website is required (URL or bare domain), name is used for the Companies House lookup |
companiesHouseApiKey | Optional, free — register at developer.companieshouse.gov.uk. Only used as a fallback, and only helps for UK-registered companies |
usePatternGuessing | Whether to fall back to pattern generation when no email is scraped (default on) |
maxResults | Max companies to process (free trial capped at 10) |
Known limitations
- Marketing/demo-heavy websites occasionally have example or placeholder customer data embedded in the page (e.g. a fictional case-study name); scraping can't perfectly distinguish that from a real contact. Treat scraped results with generic-looking name patterns on marketing pages with a little skepticism.
- Pattern guessing only fires when a director/contact name is available (currently via UK Companies House) — non-UK companies with no published email will come back with no result rather than a guess with nothing to base it on.
- MX verification confirms the domain can receive mail, not that the specific mailbox exists — it filters out addresses that definitely won't deliver, not a full deliverability guarantee.
