Unlimited free email aliases with custom domain and reply support
33mail ranks #6 of 10 in Email alias services, with an Alt Score of 60. It is freemium from $1/mo and available on the web. 5 of 9 checklist rows are verified against a public source.
33mail is a long-running (since 2011) email aliasing service that generates unlimited disposable forwarding addresses to protect a user's real inbox, with anonymous reply and a Chrome extension. Custom domain support and priority processing are available on a low-cost paid tier.
Individuals who want to give a distinct email alias to every website or service they sign up for, so they can trace which company leaked or sold their address and block that sender without exposing or changing their real inbox address.
A free (Lite) tier that issues unlimited forwarding aliases at a personal 33mail.com subdomain with a 10MB monthly bandwidth cap and no custom domain or reply support, plus paid tiers (Premium $1/mo, Pro $5/mo, Enterprise $50/mo) that add custom domain support, higher bandwidth, anonymous reply-through, and additional usernames.
A user signs up to get a subdomain like you.33mail.com, then makes up an alias such as [email protected] when a site requests an email address; 33mail automatically creates that alias and forwards mail sent to it to the user's real inbox the first time it receives a message, and the user can block any individual alias directly from the forwarded email.
