Find Hidden Emails on Any Website — The Automated Lead Gen Approach

#marketing #productivity #tutorial #webdev

Most websites hide their email addresses. But they're always somewhere in the HTML — in mailto links, contact pages, footer text, or team pages.

Here's how to find them automatically.

Where Emails Hide

mailto: links — highest confidence, verified by the site owner
Contact/About/Team pages — usually contains multiple emails
Footer — often has a general contact email
JavaScript — sometimes emails are loaded dynamically
Obfuscated text — user [at] domain [dot] com patterns

The Automated Approach

A crawler that:

Fetches the homepage
Finds internal links (prioritizes /contact, /about, /team)
Crawls 2-3 levels deep
Extracts emails via regex + mailto: detection
Deduplicates and filters junk (noreply, test domains)
