Give every domain you own a real email presence — a developer-friendly sending API, post-quantum-sealed mailboxes, passkey login, and a fraud engine that screens every message. One platform across all your domains.
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.
Each address on each domain inherits the full stack automatically.
Resend-shaped 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.

Hash-chained, re-verified on read — evidence an action was consented and logged.
