EmailAlias - Email Aliases with Leak Detection

About

EmailAlias.io — Disposable Email Aliases with Built-in Leak Detection

Stop handing your real email to every newsletter, app, and online store. EmailAlias creates a unique forwarding address for each site you sign up to — so you stay in control of what reaches your inbox, and you know exactly who leaked your address the moment spam shows up.

═════════════════════════════════════════════════════════════
WHY USE EMAILALIAS.IO?
═════════════════════════════════════════════════════════════

• Your real email stays private. Every signup gets its own alias.
• When an alias starts receiving spam, you know which site leaked or sold it. Disable that alias in one click and the spam stops.
• Reply from any alias without revealing your real address (Premium).
• Block specific senders or entire spam categories before mail ever hits your inbox.
• See which aliases have been spotted in known data breaches.

═════════════════════════════════════════════════════════════
HOW IT WORKS
═════════════════════════════════════════════════════════════

1. Visit any signup form (Facebook, ChatGPT, GitHub, your favorite store…).
2. A small "alias" badge appears next to the email field.
3. Click it — EmailAlias.io generates a fresh `[email protected]` address and fills it in for you.
4. Mail sent to that alias is forwarded to your real inbox.
5. The alias is yours forever — rename it, disable it, or delete it whenever you want.

Already created an alias for that site in another browser? EmailAlias.io detects it and reuses the same alias automatically — no duplicates.

FEATURES
═════════════════════════════════════════════════════════════

✓ INLINE ALIAS CREATION
  Works on practically any signup form, including ones that hide the field's attributes (Facebook) or render inside modals (ChatGPT).

✓ LEAK DETECTION
  Every forwarded message is tagged with the alias it came through, so you know exactly which site is leaking your address.

✓ SPAM FILTERING
  Built-in subject and frequency rules drop obvious junk before it ever reaches your inbox. Add custom allow/block lists for fine control.

✓ EXPOSURE ALERTS
  Get notified the moment an alias of yours surfaces in a known data breach so you can rotate it before the spam wave starts.

✓ CUSTOM DOMAINS  (Premium)
  Use your own domain instead of @emailalias.io for a more professional look. Up to 5 custom domains on the Premium plan.

✓ REPLY FROM ANY ALIAS  (Premium)
  Respond to forwarded mail without revealing your real address — the reply goes out from the alias the original message arrived at.

✓ KEYBOARD SHORTCUT
  Press Ctrl+Shift+E (or ⌘+Shift+E on Mac) to create an alias for the current site and copy it to your clipboard instantly.

✓ RIGHT-CLICK MENU
  Create an alias for the current page from the browser's context menu without leaving the form.

✓ CROSS-BROWSER
  Available for Chrome, Firefox, Edge, and Opera. Aliases sync through your EmailAlias account, so the alias you created on your laptop is ready on your phone.

PRIVACY
═════════════════════════════════════════════════════════════

EmailAlias is privacy-first by design:

• Your API key is stored locally in your browser. It never leaves except in authenticated requests to emailalias.io/api.
• We do NOT track which sites you visit. The content script only acts when you click the alias badge or use the keyboard shortcut.
• We do NOT inject scripts into the page or modify forms beyond placing our badge next to detected email fields.
• Source code is published and reproducible — the bundle running in your browser can be rebuilt from the public repository.
