About Addy.io
What is Addy.io?
Addy.io is a free, open-source anonymous email forwarding tool. It lets you generate unique email aliases for every website you sign up for. Instead of sharing your real email address, you give each service a different alias. Emails sent to that alias are forwarded to your real inbox, but your true address stays hidden.
What problem does it solve?
Every time you sign up for a newsletter, a trial, or an online shop, you risk your email being sold or leaked. Addy.io solves this by allowing you to create a disposable address for each service. If one alias starts receiving spam or unwanted mail, you simply deactivate or delete it from your dashboard — the spam stops instantly without affecting your main inbox.
Who is it for?
Addy.io is ideal for privacy-conscious individuals, remote workers, freelancers, and anyone who frequently signs up for online services. It's perfect for people who want to control their inbox and avoid spam. It is not intended for teams needing shared inbox management or complex email automations.
Real use cases
A freelance designer uses separate aliases for each client project — when a project ends, they deactivate that alias. An online shopper creates a new alias for every store to avoid marketing emails. A journalist uses a random alias for sensitive sign-ups to protect their identity.
Key features
- Unlimited aliases (free plan) — Create as many aliases as you need; each one forwards to your real inbox, keeping your main address private.
- Mobile apps (iOS & Android) — Manage aliases, deactivate or delete them on the go with open-source mobile apps that are free to use.
- Browser extension — Generate a new alias in two clicks while browsing, with official extensions for Firefox, Chrome, Edge, Safari, and Chromium-based browsers.
- GPG / OpenPGP encryption — Add your own public keys to encrypt forwarded messages; only you can decrypt them with your private key.
- Custom domains — Bring your own domain and create addresses like anything@yourdomain.com, with optional catch-all or regex-based alias creation.
- Random alias generation — Generate one-off aliases like x481n904@anonaddy.me that don't include your username, boosting anonymity.
