Gmail Alias Toolkit helps you create and manage Gmail address variations for sign-ups, testing, inbox organization, and account tracing. It supports +tag aliases, Gmail dot variations, reusable presets, history, favorites, statistics, and multiple Gmail accounts.

Generate aliases

Create random aliases, custom tags, dot variations, googlemail.com variants, and combined Gmail tricks.

Organize your history

Search, filter, sort, favorite, export, and generate QR codes for saved aliases.

Use multiple accounts

Keep history, favorites, and statistics isolated for each configured Gmail account.

Local-first privacy

Alias data and settings stay in browser extension storage. No account or remote alias-generation service is required.

How Gmail aliases work

Suppose your address is david.nguyen@gmail.com:
For personal @gmail.com accounts, these variants normally arrive in the same inbox. They do not create separate Google accounts or mailboxes.
Gmail aliases improve organization, but they are not anonymous addresses. A website may remove dots, strip everything after +, or reject alias formats entirely.

​
Common uses

  • Identify which service received or shared an address.
  • Create readable tags such as +shopping, +work, or +newsletter.
  • Generate test addresses without creating additional Gmail accounts.
  • Keep frequently used aliases as presets or favorites.
  • Separate alias records between personal, work, and testing accounts.
