MailMask
MailMask creates unique email aliases that forward incoming messages to an existing mailbox. Aliases can be created, disabled, or removed; disabling one immediately stops new mail from being accepted. MailMask is not a mailbox or email-provider replacement, and it cannot send messages from alias addresses. The service says it processes email only for forwarding and does not retain message content longer than technically necessary for delivery. Its infrastructure and data handling remain within Europe, under European law including the GDPR. MailMask says it uses no advertising, analytics, or third-party tracking, and does not sell or share user data. The Free plan costs nothing for aliases and forwarding, with no price or usage limits stated. The operator describes it as a personal risk-reduction layer, not for critical, account-recovery, or mission-critical communication. Availability is best-effort, and uninterrupted service is not guaranteed.
