Hide Your Email on a Personal Site
For personal portfolios and blogs, obfuscation cuts spam from contact-page scrapers.
HTML entities (recommended)
Each character becomes a numeric HTML entity. Browsers render it as the original email, but most simple scrapers reading the raw HTML see gibberish.
<a href="mailto:hello@example.com">hello@example.com</a>
How it renders in a browser:
π‘ Modern spam bots are sophisticated. Obfuscation slows them down but isnβt bulletproof. For maximum protection, combine with: server-side rate limiting on contact forms, honeypot fields, and reCAPTCHA-equivalent. For low-stakes use (a contact page on a small site), HTML entity obfuscation cuts scraper hits by ~60-80%.
Personal Sites tips
For personal sites without a mail server (just a contact link), obfuscating your email stops most spam scrapers.
The "HTML entities" method is the best balance of compatibility and protection β works without JavaScript and renders correctly for all users.
For maximum protection, use JavaScript assembly β scrapers without JS engines will miss the address entirely.
