About 3Z Mail

3Z Mail Services Ltd is a small email hosting provider based in Wellington, New Zealand. We were founded in 2018 with a straightforward goal: to offer private, no-nonsense email hosting for people who do not want their correspondence mined for advertising data.

We are not a large organisation. The team consists of a handful of engineers and sysadmins who believe that email should be boring infrastructure, not a surveillance platform. We run our own hardware in Auckland and manage every layer of the stack, from the mail transfer agent to the web client.

What we do

We provide standard email services: IMAP, SMTP, and a webmail interface. You can use our web client or connect any third-party email application. We support custom domains for users who need them.

Our service is deliberately simple. We do not offer calendar syncing, file storage, video conferencing, or any of the dozen other things that large providers bundle into their email products. We do one thing, and we try to do it well.

Our approach to privacy

We do not scan your email. We do not build advertising profiles. We do not sell or share your data with anyone. The only information we retain is what is necessary to operate the service: your email address, a hashed password, and the messages in your mailbox.

Because our servers are located in New Zealand, your data is subject to the Privacy Act 2020. We believe that jurisdictional integrity matters. We have no offshore subsidiaries, no parent company in another country, and no arrangements that would expose your data to foreign legal regimes.

Current status

3Z Mail is not currently accepting new users. We operate the service at a small scale by design, and we have reached our current capacity. Existing users are unaffected.

If you would like to be notified when registration reopens, you can join the waitlist on our signup page.

The name

"Triple Zero" refers to our three commitments: zero spam, zero tracking, and zero compromise on privacy. The domain 3z.nz is short and was available. That is the full story.
