33Mail review
A low-cost alias service for forwarding mail and replying anonymously.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
33Mail is an email alias and forwarding service for individuals who want separate addresses for websites, newsletters, and online services. It automatically creates aliases under a 33mail.com subdomain when they first receive email, forwards messages to an existing inbox, and lets users block unwanted aliases. Its anonymous-reply feature supports responses without exposing the receiving address, making 33Mail a fit for people who want practical separation between online services and their primary inbox.
The plan structure focuses on alias volume and message handling rather than a fixed alias count: the published plans show unlimited aliases. Lite includes unlimited aliases and an alias management interface. Premium costs $1 per month and adds 50 MB of monthly bandwidth, 20 anonymous replies per day, one custom domain, and one additional username. Pro costs $5 per month with 500 MB of monthly bandwidth, 100 anonymous replies per day, five custom domains, and five additional usernames. Enterprise costs $50 per month and raises those allowances to 5 GB, 1,000 anonymous replies per day, unlimited custom domains, and 25 additional usernames. A free tier is also available.
The standout feature is automatic alias creation combined with forwarding, blocking, and anonymous replies. Paid tiers extend the service to custom-domain aliases, while a Chrome extension can fill alias signup fields in supported browser workflows. 33Mail is available on the web and through the Chrome extension, so its ecosystem is focused rather than broad. It is a good choice for simple alias management, disposable addresses, and privacy-conscious replies. Choose an alternative if you need a mobile app, broader platform coverage, or the ability to send new outbound messages directly from an alias.
