Give every domain a real email presence — a developer-friendly sending API, post-quantum-sealed mailboxes, passkey login, and a fraud engine that screens every message. Or let your own users send and receive on your domain.
ISET.email turns your domains into a working email platform — sending, receiving, mailboxes, and compliance — without stitching together five vendors. Your developers get a clean API; your people get real addresses; every message carries a verifiable sovereign signature.
A clean transactional API your developers drop in. DKIM-signed, with a verifiable signature on every message.
Real addresses on any domain — compliance@yourbrand.com — delivered to sealed mailboxes.
Passkey login, account safeguards, and a fraud engine that screens phishing, spoofing and scams.
Run an app, a community, a newsletter, or a SaaS? Issue a real name@yourdomain.com mailbox to every user or subscriber — you stay the brand, we run the email. The same engine that powers our own apps, opened up to you by API.
One click: we mint your API key, generate your DKIM keys, and hand you the exact DNS records (MX · SPF · DKIM · DMARC). Verify and you’re live.
One API call creates user@yourdomain.com for each of your members — sealed, per-user, non-custodial. You can create; you can never read their mail.
Embed a white-label mailbox your users reach with one-tap SSO — no second login, no “powered by” — plus search-and-message and encrypted calling between your members.
Already powering live products that issue email to their own members. Bring your domain and do the same in minutes.
Each address on each domain inherits the full stack automatically.
A familiar, drop-in send endpoint, domain onboarding with SPF·DKIM·DMARC, webhooks, and a TypeScript SDK.
Mailboxes sealed at rest with post-quantum encryption. The server stores ciphertext, not your mail.
Phishing-resistant passkeys, purpose-bound consent, kill-switch & money-lock, court-admissible audit.
Every message screened for phishing, spoofing, scams and anomalies — blocked on send, quarantined on receipt.
Add your domain and publish the DNS records we generate — shown as ready-to-paste fields.
Mint any address — role@yourdomain.com — no per-address setup.
Call POST /v1/emails to send; inbound mail lands sealed in the mailbox.
Signed with a post-quantum signature and screened for fraud — verifiable by anyone.
// one SDK, every domain import { ISETEmail } from '@iset/email'; const email = new ISETEmail({ apiKey }); await email.send({ from: 'compliance@fiduciary.technology', to: 'user@example.com', subject: 'Your signed receipt', html: '<p>Post-quantum signed · screened</p>', }); // screen anything — even mail from // another platform you connect await email.scan({ from, subject, html });
The sovereign layer is the same; you choose the delivery backend that fits where you are today.

Mailboxes sealed to the holder's key. Offline-first option means the server keeps no secret at all.
Hash-chained, re-verified on read — evidence an action was consented and logged.
