addy.io vs Spamex

addy.io creates email aliases that forward messages to a real inbox, allowing users to give out aliases instead of their main address. An alias can be deactivated to silently discard new mail or deleted so senders receive a bounce. Users can connect a domain they control and set catch-all controls. Paid features allow replying to forwarded messages or starting messages from an alias without revealing the real address. Users can add GPG/OpenPGP public keys for recipients to encrypt forwarded mail, with an option to hide and encrypt the subject. The maker lists free open-source apps for iOS and Android, browser extensions for several browsers, and an API for automating aliases and other account resources. Self-hosting instructions and two-factor authentication are also available. The free plan includes unlimited standard aliases, but sets limits for shared-domain aliases, recipients, available alias domains, and monthly bandwidth. Paid plans start at $1 a month billed yearly; higher tiers list more recipients and custom domains, among other additions.
