How your mail leaves NorthRelay

Verified sender

You can only send from domains you own and have verified. Nobody sends as you.

One clean relay

sovereign.north-pipe.ca — DKIM-signed for your domain, SPF and DMARC aligned.

Reputation guard

Bounces and complaints suppressed automatically. One-click unsubscribe on bulk mail.

Canadian infrastructure · monitored around the clock

Most email relays share IP addresses across all customers. Anyone can sign up and send from any address, and one spammer tanks everyone's deliverability. Your carefully crafted emails land in spam — and you have zero control.

Traditional Relay

Your emails share an IP with thousands of unvetted senders. Any one of them can get that IP blacklisted overnight.

Sender A

Sender B (you)

Shared reputation — all affected

NorthRelay

Every From address must belong to a domain its owner verified, and the one sending IP is monitored around the clock. Abuse is stopped before it reaches the queue.

Unverified

Your mail

Guarded reputation — verified senders only

How It Works

From signup to first send in under 5 minutes.

Pick a domain, get sending in minutes

Choose from 5 system domains with SPF, DKIM, and DMARC pre-configured, or verify your own domain with the records we hand you. First email in under 5 minutes.

Send from your code or your agent

REST API, TypeScript and Python SDKs, or the MCP server from Claude and Cursor. Templates, campaigns, scheduled and batch sends, all behind one API key.

Your reputation, monitored 24/7

Bounces and complaints are suppressed automatically, incidents are detected and explained, and an hourly canary proves mail is landing with SPF, DKIM and DMARC passing.

Everything you need to send with confidence

From zero-config subdomains to a monitored sending IP, NorthRelay gives you the infrastructure serious senders rely on.

One clean sending IP

Every message leaves through a single monitored relay with DKIM, SPF and DMARC aligned to your domain. Verified senders only, so nobody can burn the IP you send from.

Your domain, or ours, in minutes

A system subdomain is live the moment you sign up. Add your own domain from the $5 Starter plan with the exact DNS records to paste and live verification.

Deliverability tooling included

Reputation score and incidents, blocklist monitor across 13 providers, DNS and pre-flight checks, link scanner, and DMARC and TLS reports read for you.

API, SDKs and MCP server

REST API with OpenAPI, TypeScript and Python SDKs, signed webhooks, and an MCP server with 80+ tools so your AI agents can send and investigate.

Campaigns and NorthRelay Studio

Contact lists, A/B tests, approval workflow and one-click unsubscribe, plus versioned, brandable email designs your product calls by key.

NorthRelay Studio

Programmable email design for the products you ship

Studio turns templates into versioned, brandable releases your application calls by key. Design in the dashboard or push from code, publish, and let your product send the right version every time. It is the engine behind our own operational digests, and it is included from the Micro plan.

Brands: colours, logo, fonts, sender defaults and footer, shared by every template through {{theme.*}} variables
Templates with Handlebars-safe rendering, sample data previews and a starter gallery
Immutable releases with revision checks and one-click rollback
Sends that are idempotent and attributable: every delivery keeps the release it was rendered from
Application credentials scoped to one product and its verified senders, so an integration can never escape its lane
Export and apply a design manifest from CI, or edit in the dashboard; both end in the same release
