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.
No identity verification is recorded for typical use. No document identity verification found for the alias service. Account, destination mailbox, alias and payment metadata still exist, and the service is now contracted through Proton AG in Switzerland.
