About Extract Email Addresses
Email addresses are pulled out of surrounding text by pattern. Worth being honest about the limit: the RFC 5322 grammar for a valid address permits quoted strings, comments and nested parentheses, and the complete regular expression for it runs to several thousand characters. This uses a practical pattern that matches essentially every real-world address and rejects the pathological ones nobody actually uses.

Questions
Will it find every address?
Every ordinary one. Addresses with quoted local parts (`"john doe"@example.com`) or IP-literal domains are valid per the RFC and are not matched, because matching them reliably means implementing the full grammar.
Does it verify the addresses exist?
No — that would require contacting a mail server, and this tool never makes a network request. It extracts what looks like an address; whether it receives mail is a separate question.
