VanishInbox — Disposable Email by Alex K

VanishInbox gives you a disposable email address instantly — no sign-up, no personal info required.
Use it whenever a website asks for your email but you don't want spam, tracking, or marketing in your real inbox. Your address auto-deletes after 10 minutes, taking all received emails with it.
How it works
Click the extension icon to generate a disposable address. Copy it with one click, or right-click any email field on a page and select "Fill with VanishInbox address" to autofill it automatically. Emails arrive in the built-in inbox and are checked every 5 seconds — no need to visit the website.
