A free, browser-based generator for unlimited Gmail aliases. One real inbox, thousands of disposable addresses.
extragmail turns a single Gmail address into thousands of unique, working aliases using Gmail's built-in dot and plus-tag rules. Every alias delivers to the same inbox. The tool is 100% client-side: no account, no server, no tracking. A Chrome extension can insert aliases directly into any signup form.
| Feature | What it does |
|---|---|
| Dot-variant generator | Enumerates or samples valid dot placements (up to 2^(n-1)). |
| Plus-tag generator | Appends +tag by category, custom list, or random token. |
| Custom patterns | Token engine: {first}, {tag}, {date:YYYYMMDD}, {n:4}, {rand:6}. |
| Site-specific aliases | One alias per service for 100+ popular sites, with per-category CSV export. |
| Bulk export | TXT, CSV, XLSX, or clipboard. |
| Saved batches | Local library with import (TXT/CSV) and re-export. |

Gmail ignores dots in the local part and ignores everything after a +. So john.doe@gmail.com and johndoe+shop@gmail.com deliver to the same inbox.
No. extragmail is fully client-side. Your email never leaves your browser.
Dot-variants are accepted everywhere. Plus-tag aliases are accepted by most sites; a small minority reject +, in which case use a dot-variant.
Up to 10,000+ in a single batch. There is no daily limit.
