Email Alias Creator
Turn one address into eight purpose-tagged plus-aliases — shopping, newsletters, signups, trials and more — so every service gets its own address and the spam tells you exactly who leaked it.
Features
Eight purpose-tagged aliases: shopping, newsletters, temporary use, testing, signups, trials, info and automated mail
Standard plus-addressing — works with Gmail and other providers that support +tags
One-click copy per alias, with confirmation
Each alias labeled with its purpose, so spam traces back to its source
All mail still lands in your main inbox; aliases need no setup
Generated in your browser — your address is never sent anywhere
How to Use

Click Generate Aliases
Copy the alias that matches each purpose and use it for that signup
When spam arrives, the To: address names the source
Filter or block that alias in your provider's rules

Frequently Asked Questions
- What is the Gmail plus trick (+alias) and how does it work?
- Gmail — and several other providers — ignores everything between a plus sign and the @ in the local part, so name+shop@gmail.com delivers to name@gmail.com. The tag survives in the To: header, which makes it a free, zero-setup labeling system: one alias per service, with filters and leak-tracing built on top.
- Can websites strip the +tag and see my real address?
- Yes, trivially — the base address is visible inside the alias, and list-cleaning software routinely strips plus-tags. Plus-aliases are a convenience layer for honest senders, not an anonymity tool. When a site should not know your real mailbox at all, that is the job of a temporary email address.
- Do plus-addresses work on Outlook, Yahoo, and iCloud too?
- Outlook.com and iCloud Mail support plus-addressing like Gmail, as do Proton Mail and Fastmail. Yahoo does not use plus signs — it offers separate keyword-based 'disposable addresses' in its settings instead. One caveat everywhere: some signup forms incorrectly reject the + character.
- Email alias vs temporary email — which should I use when?
- Aliases for things you want long-term but compartmentalized: shopping accounts, newsletters, anything with receipts. Temporary email for things you want gone: one-time downloads, trials, unknown sites. The deciding question is whether this sender should ever be able to reach you again.
- How do I find out which company leaked or sold my email address?
- Give every service a different alias, then read the To: line on the spam that arrives. If mail addressed to you+shop comes from someone who is not that shop, you know exactly who shared the list. From there, filter the alias to trash and unsubscribe or complain with evidence in hand.
