Fun Facts

• The @ symbol in email was chosen by Ray Tomlinson in 1971 for ARPANET email because it was rarely used in names and already meant 'at' in English.
• The official email address specification (RFC 5321/5322) allows surprisingly complex local parts — technically, "john..doe"@example.com is valid with quoted strings.
• There are approximately 4.5 billion email addresses worldwide as of 2024, with the average office worker receiving 121 emails per day according to a Radicati Group study.

FAQ

What email formats does it catch?

RFC 5322 addresses: local@domain.tld, quoted locals, plus-addresses (user+tag@…), subdomains. It skips mailto: prefixes automatically.

Will it catch obfuscated emails like 'user at example dot com'?

Optional — toggle 'loose mode' to recognize common obfuscations (spaces around @, 'at'/'dot' word substitutions). Default mode is strict and only matches real email syntax.

Does it validate the emails?

Structurally yes (valid syntax). Semantically no — it doesn't check if the domain exists or the mailbox is live. Use an email verification service for that.
