AnonAddy is an open-source anonymous email forwarding service created in 2019 by developer Will Browning. In 2024 the product was rebranded to addy.io, though the underlying open-source codebase and functionality are unchanged.
Key Features
Users generate unique email aliases per website or contact, using a personal username, random string, or custom domain, which forward to a single real inbox. Replies can be sent anonymously from an alias, forwarded mail can be encrypted with GPG/OpenPGP, and a single alias can route to multiple recipients. A developer API supports automation, and the service ships browser extensions for Firefox, Chrome, Edge, and Safari plus native iOS and Android apps.
Pricing Overview
The Free plan includes 10 shared-domain aliases and 1 recipient. The Lite plan starts around $1/month billed yearly with higher limits, and the Pro plan starts around $3/month billed yearly (or $4/month billed monthly) with unlimited shared-domain aliases, more recipients, and higher daily reply limits.
