Frequently Asked Questions
How does the email extractor identify valid email addresses in unstructured text?
The extractor uses an optimized RFC 5322 regex pattern: `[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}`. It scans through unformatted text, HTML tags, log files, and PDFs, identifying and extracting valid email patterns while ignoring surrounding punctuation and HTML markup.
How does the tool handle obfuscated email addresses (e.g., name [at] domain [dot] com)?
Our extractor includes a de-obfuscation parser that automatically identifies and resolves common anti-scraping formats (such as `user [at] example.com` or `user(at)example.dot.com`), converting them back into standard RFC email format.
Can it extract emails from messy HTML source code?
Yes. The extractor ignores all `<a href="mailto:...">` tags, HTML classes, scripts, and stylesheet code, extracting only the clean email addresses without surrounding HTML tags.
Is there a limit on how many emails can be extracted at once?
Because processing executes in local browser memory using fast compiled regular expressions, the tool can effortlessly process tens of thousands of email addresses from multi-megabyte documents in milliseconds.
