Analysis

OVERVIEW

SimpleLogin forwards email through aliases without exposing the destination mailbox to senders, remains open source and self-hostable, and has operated under Proton AG's Swiss terms since joining Proton in April 2022.

LIMITS

No independent security audit is recorded for the alias service itself, and hiding the destination address from senders does not remove the account, mailbox and payment metadata still linked inside the service.

USEFUL FOR

Existing Proton ecosystem users who want alias-based forwarding built into that account, aware that Swiss Proton AG terms now govern the service.
