Chrome Extension One-click email autofill,
for every website.
Generate a unique email address for every signup. Track who shares your data, filter spam easily, and stay in control. All without typing.
How It Works
Three steps. One-time setup.
Then it's just one click.
- 1 Configure once
-
Enter your email address or domain in settings. The extension detects your provider automatically.
- 2 Visit any website
-
Navigate to any signup or login page. github.com, amazon.com, spotify.com, anywhere.
- 3 Click the icon
-
Clean Autofill generates a unique email and fills it into the form. Done.
- github.com github.com@yourdomain.com Catch-All
- github.com you+github.com@gmail.com Plus Addressing
- amazon.com amazon.com@yourdomain.com Catch-All
- amazon.com you+amazon.com@gmail.com Plus Addressing
Two Modes, Works With Any Email
Clean Autofill supports two email generation modes. The extension detects your provider and shows which mode works for you.
Plus-Addressing
Most Users
you+website.com@gmail.com
- Uses the + trick supported by Gmail, Outlook, ProtonMail, Fastmail, and more
- No special setup required. Works with your existing email
- Enter your full email address and you're ready to go
- Heads-up: a few signup forms strip the + character. Catch-All mode avoids this.
Catch-All Prefix
Power Users
website.com@yourdomain.com
- Uses your custom domain with catch-all email routing
- Cleanest format. The site domain becomes the email prefix
- Best for users who own their email domain
- Resilient: never stripped or blocked by signup forms that reject the + character
Most users do fine with Plus-Addressing. If you own a domain, Catch-All is more robust because some signup forms strip the + character. The extension auto-detects your provider and shows which modes work for you.

One click on any signup form. The email is generated, filled, and ready to go.
Why Use Unique Email Addresses?
Every signup gets its own address. Here's why that matters.
- Track Data Leaks
- Instantly know which company sold or leaked your email address. Each site has a unique address that traces back to the source.
- Filter Your Inbox
- Create inbox rules based on which address received the mail. Organize by service without manual labels.
- Control Spam
- Disable a single address without affecting everything else. Cut off spam at the source.
- Stay Organized
- Every signup has its own address, automatically. No more wondering which email you used for which service.
