33Mail vs AliasVault

33Mail creates private email aliases and forwards messages sent to them to an existing email address. An alias is created automatically when email first arrives, and users can block an alias to stop receiving its messages. With anonymous replies enabled, users can reply to forwarded mail through 33Mail; the service removes header information relating to their actual email address. Premium accounts can use a custom domain by pointing its MX record to 33Mail. The service is web-based and also lists a browser extension. Lite is free and includes 10MB monthly bandwidth, with alias creation limited to five per 30-minute period. Premium costs $1 a month and includes 50MB monthly bandwidth, 20 anonymous replies per day, one custom domain, and one additional username. Pro costs $5 a month; Enterprise costs $50 a month. Attachments up to 10MB count toward bandwidth, which is measured over a rolling 30-day window. 33Mail says it warns users who exceed their bandwidth limit and treats dropping emails as a last resort. Its terms say user data is used to provide the service and is not shared with third parties except as needed for law enforcement requests. Brothers Ian and Andrew Clarke conceived the service, which forwarded its first email in August 2010.

AliasVault is a password manager that combines password storage with email aliases and a built-in two-factor authenticator. Its Free plan lists all product features, password management, aliases, offline mode, and device synchronization, but no price is listed. Passwordless account login and passkey support are available. AliasVault can be used on the web, iOS, and Android, through extensions for Chrome, Firefox, Edge, and Safari, or in a self-hosted setup. The maker lists the Netherlands as its headquarters and 2024 as its founding year. The product does not offer secure sharing or business admin controls. A Premium plan lists higher alias and email-storage limits and VIP alias domains; a Family plan lists Premium benefits for households and up to six accounts. Both are marked as coming soon, and neither has a listed price. That makes the current listed offering focused on individual password management and alias use rather than shared or business administration.
