Our verdict on addy.io

addy.io is an open-source email alias and forwarding service for people who want to avoid sharing their primary email address. It lets users create standard and shared-domain aliases, forward messages to verified recipients, deactivate or delete aliases, and reply to or send new messages from an alias. Access is available through the web, iOS, Android, a Chrome extension, an API, and self-hosting documentation.

The plan structure covers casual and more advanced use. The Free plan costs $0 per month and includes unlimited standard aliases, 10 active shared-domain aliases, one recipient, and 10 MB of monthly bandwidth. Lite costs $1 per month when billed annually, adding 50 active shared-domain aliases, one custom domain, and 50 anonymous replies or sends per day. Pro costs $3 per month billed annually or $4 per month billed monthly, with unlimited active shared-domain aliases, 20 custom domains, and 200 anonymous replies or sends per day. Duo and Family extend Pro features to two and five members, respectively, with independent accounts and optional custom-domain sharing.

Its wider platform coverage is a notable strength for buyers who want more than browser-based forwarding. Mobile apps and a browser extension support alias management, while the API supports resource automation. GPG/OpenPGP encryption is available for forwarded messages, and self-hosting documentation gives technically capable users another deployment path. The trade-off is that the free tier is constrained to one recipient, limited bandwidth, and no listed custom-domain access, while higher-volume sending and broader domain support require paid plans. Choose addy.io if you want aliases plus sending, replies, encryption options, and multiple access methods; choose an alternative if you need a simpler service with fewer plan distinctions or no self-hosting interest.
