Subify is a browser extension for Google Chrome¹ that enables you to create unique subaddresses for the websites you visit. Subaddressing is a feature of most email providers that allows you to tag your existing email address with additional information (e.g. john.doe+my.custom.tag@example.com). The best part is that emails sent to the subaddress are delivered to the inbox you already use.

• Manage your inbox with filters and rules based on the subaddress.
• Protect your privacy by providing unique email addresses at sign-up².
• Create test accounts for development and testing.
• Identify the source of spam and unwanted emails.

Features

• Add multiple email addresses from the Generate tab³
• Choose between presets (e.g. custom, domain, and timestamp).
• Autofill input fields from the right-click context menu.
• Manage copied and autofilled subaddresses from the History tab.

Permissions

The extension requests only necessary permissions in order to respect user privacy and adhere to the Chrome Web Store's updated privacy policy.

• activeTab - Allows the extension to retrieve the URL of the currently active tab when requested by the user and provide context in history
• contextMenus - Allows the extension to add a context menu item for autofill on input fields
• scripting - Allows the extension to perform autofill on active input fields

Footnotes

1. Currently only available for Google Chrome and other supported Chromium-based browsers, but may be made available for other browsers in the future. ↩

2. Some websites may sell your email address to third parties, which can lead to unsolicited emails. By using subaddressing, you can identify the source of the spam and block future emails. ↩

3. The extension only supports subaddressing with single-character separators (e.g. + or -). It doesn't support subdomain addressing. ↩
