33Mail vs Alias Email

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.

Alias Email creates alternative email addresses that forward messages to a primary inbox, helping users keep their main address private and organize incoming mail. Aliases can use personal or business domains, send anonymous email, and forward to multiple recipients. The browser extension can generate an alias from an email field, including in website forms, popups, modals, and online chats; it is listed for Chrome, Safari, Firefox, Edge, Opera, Vivaldi, Brave, and Tor. Alias Email says it removes trackers from forwarded messages and allows a PGP public key to encrypt messages before forwarding, while the user keeps the private key. Forwarded mail is not stored except during service outages, when it may be held temporarily for up to three days. The service says it uses TLS, SPF, and DKIM, is GDPR compliant, and does not sell or disclose user data. Its free plan includes 10 aliases and one custom domain. Premium costs $39.96 a year, equivalent to $3.33/month billed annually, and includes unlimited aliases and two custom domains. There are no mobile apps.
