Generate unlimited Gmail aliases
from one inbox — free, forever.
Create up to 10,000 unique Gmail addresses using dot-variants and plus-tags. Every alias forwards to your real inbox. No signup. No tracking. Built for signups, testing, and beating spam.
Gmail ignores dots. Every variant lands in the same inbox — perfect for tracking signups.
Your inbox is leaking.
Every site you sign up for shares, sells, or loses your email. You don't know who's spamming you — and you can't stop it without burning your address.
Spam you can't trace
No way to know which signup leaked your email.
One address everywhere
If it's compromised once, every account is exposed.
Throwaway inboxes break
Temp-mail services expire. You lose the account.
Why temp-mail and second accounts fail
Temp-mail services
Inboxes expire. You can't recover the account or reset passwords. Many sites block them.
A second Gmail account
Another inbox to monitor, another password to manage. Still one address per signup.
One real inbox. Thousands of disposable aliases.
Gmail already ignores dots and everything after a +. extragmail turns that into a superpower.
Unlimited aliases
Generate 100 to 10,000+ unique addresses in one click.
Track who leaked
Use a different alias per site and instantly spot the source of spam.
Stays in your browser
Nothing uploaded. No account. No tracking. We never see your email.
Built for people who hate spam

Why we built this
We were drowning in newsletters we never signed up for. After getting another "data breach" email, we wanted to know exactly which site had leaked our address — and stop it. Gmail's built-in alias rules already make it possible. extragmail just turns them into a fast, free tool anyone can use. No account, no upsell, no tracking. Just a generator that runs in your browser.
Pricing

Your privacy, guaranteed
extragmail runs 100% in your browser. We don't store your Gmail address. We don't send it anywhere. We don't have a server that even could. Check the source — or use it offline.
