Claim an Australian email.

What you get

• Your name on a sovereign Australian domain. your-name@aloomu.au. Yours.
• IMAPS + SMTP submission for any mail client (Outlook, Apple Mail, Thunderbird, mobile).
• Cryptographic identity signed by AloomU's own root CA — see /trust for the verification posture.
• DKIM-signed outbound from a real, live MTA — no foreign relay rewriting your envelope.
• Same hardware that runs the rest of AloomU. You can watch its live capacity at /#live.

The honest disclosure (full disclosure)

We're at Stage-0 lab posture — that means the entire AloomU mail service runs on one rack at Moorooka in Brisbane. One NVIDIA RTX 4090. Roughly 47 GB of host RAM. A single SSD volume. Residential FTTP connection (Optus, dynamic IP) backed by 17 kW solar + 50 kWh battery storage. Production-grade hardware lands at Macquarie Data Centres Sydney in 2026 Q4 (charter milestone M6). Until then, the limits below are real:

• Hard cap: 50 mailboxes for the first cohort. Each mailbox gets a 1 GB quota. After 50, the waitlist queues until we either expand the rack or M6 lands. No silent expansion at the cost of existing mailboxes.
• Outbound deliverability is degraded for some recipients. Major mail providers (Gmail, Microsoft 365, ProtonMail) maintain block lists for residential ISP IP ranges. Mail you send from name@aloomu.au may land in spam or bounce when delivered to those recipients. Mail to small-business / institutional / open-MTA recipients usually works fine. The block resolves at M6 when we move to a static commercial IP.
• Inbound mail works fine. Verified end-to-end against external senders (Gmail-to-AloomU DMARC=pass, DKIM=pass, ESMTPS-encrypted).
• This is a real production mailbox, not a demo. Your password is yours. Your mail is yours. We read nothing. We're a sovereign-cloud company, not an ad business — there is no profit motive to surveil your inbox.
• No anti-spam filtering at the perimeter yet. Spam reaches your inbox until M6's mail-stack hardening lands. Apply your own client-side filtering.
• Single SSD, no off-site backup yet. If the rack burns down, your mail is gone. Off-site replication arrives at M6. Keep anything critical elsewhere too. We're a sovereign Australian email — that doesn't mean our hardware survives a house fire.
• Service availability follows the operator's workstation. Knox is the only operator at Stage-0. If he restarts the rack or loses power for longer than the 50 kWh battery covers, mail pauses. Inbound senders' MTAs queue and retry; nothing is lost. Outbound from your client during the outage will queue locally in your client.
• Mailboxes are provisioned manually. Knox reads each request, decides if it fits the AloomU posture, and replies with credentials within ~48 hours. This gates abuse and lets us be deliberate during the first cohort. Auto-provisioning lands when the abuse + identity-verification rails do.
• Free for the first cohort. No marketing list. No dark patterns. Nothing recurring is being silently scheduled. We're not adding you to anything else.

Sovereignty isn't a marketing claim — it's a chain of decisions, every one of which has tradeoffs. The tradeoffs above are the ones AloomU has chosen at Stage-0. Each one resolves at M6 (Macquarie Sydney production cutover); Stage-1 Gladstone 60 MW campus production lands at end-2029. We will publish updated limits on this page as the substrate moves.

Join the waitlist

Submit the form below and your sovereign AloomU mailbox is provisioned immediately — auto-provisioned by the rack at Moorooka, Brisbane. You'll see your password on the response page. Save it; we don't store the plaintext.

No credit card. No tracking pixels. No marketing-list opt-in (there's no marketing list). Username + password generated server-side by the rack at Moorooka, audited to data/provisioner/signups.jsonl, returned to you on the response page. Source: /.well-known/aloomu-capacity.json shows the live mailbox count.

Why this matters

You probably already have an email address. It's almost certainly hosted by Google, Microsoft, or Apple — three US-headquartered companies with full visibility into who you correspond with, when, and (often) what about. Modern mail clients give you a green padlock that promises encryption-in-transit, but the company storing your inbox sees plaintext at rest and is subject to the CLOUD Act, FISA Section 702, and Executive Order 12333 regardless of where their servers physically live.

A sovereign Australian email address is a small daily statement that this can be different. The actual security model — read your inbox, see who's writing, write back — is identical to what you have today. The legal model behind the storage layer is what changes.

AloomU isn't asking you to move your primary inbox tomorrow. It's asking you to claim your sovereign Australian identity now, use it where it counts, and migrate the rest as our production substrate matures. Read more about why AloomU exists →
