What it does
erine.email is an open-source forwarding service built around an address for each contact or signup. Messages route to an existing inbox, and aliases can be disabled individually.
erine.email organizes mail control around the address a sender received. After choosing a username and destination inbox, use a different alias for each contact. If one becomes unwanted, switch off that alias instead of changing the destination address or training another spam filter.
The project says replies can keep the destination address hidden too. Its simple address-per-use model is the main reason to consider it; aliases identify a route, not a guarantee about who originally disclosed an address. The homepage presents the service as free and open source under GPLv3.
Strengths
- One alias can be disabled while others keep forwarding.
- The existing inbox remains the message destination.
Best for
- People who prefer address-based controls over broad spam rules
