Email on your own domain.

Transactional and marketing email, sent from your own domain and your reputation. Every message is triggered by a real platform event, rendered on-brand, and authenticated with SPF, DKIM, and DMARC the moment your domain verifies. No per-email markup — one flat price.

Every email is an event, not a blast.

Outbound mail is event-driven. A platform event publishes email.send; a worker renders your template and delivers it from your verified domain — the same path for an order receipt or a six-thousand-person broadcast.

01 · trigger

A platform event fires

An order is paid, a cart is abandoned, a quote is sent — or you hit send on a broadcast.

02 · queue

email.send is published

The event lands on a durable queue with retries — nothing is sent inline, nothing is lost.

03 · render

Your template renders

A worker composes the message from atomic React Email components — HTML and plain text together.

04 · deliver

Sent from your domain

Signed with your DKIM key and delivered to the inbox, with open, click, and bounce tracked back.

One engine for both kinds of email.

Transactional messages your customers expect and marketing your team chooses to send — same domain, same reputation, same analytics. No second tool, no separate sender.

transactional · triggered

Sent the instant something happens

Order confirmations, shipping updates, password resets, quote replies — wired into every module and live from the moment Email is on. Editable, brandable, never missed.

Sent to exactly who should get it

Broadcasts target a live CRM segment — there is never a list to export. Compose, preview against a real customer, send or schedule, and watch opens and clicks roll in.

Authenticated the moment you verify.

Add your domain and sparx configures the records that get you to the inbox — SPF, DKIM, and DMARC — then watches them. Until a domain verifies, mail sends from the shared sparx domain, so you are never blocked.

(open/click tracking)

Send to a segment, watch it land.

Pick a saved CRM segment, compose, and send — or schedule it. Opens, clicks, bounces, and unsubscribes report back per send, and revenue is attributed to orders placed within 24 hours of a click. The list never leaves sparx.

Everything a sender needs.

The parts that make email actually work — building, measuring, and keeping a clean list — are all in the box, not add-ons.

Template editor

Edit on-brand templates with a variable picker, mobile and dark-mode preview, a spam-score check, and a test send to any address.

Engagement analytics

Sent, delivered, opened, clicked, bounced, and unsubscribed per send — plus attributed revenue and your best send time.

Suppressions, handled

Hard bounces and complaints suppress automatically, one-click unsubscribe is in every email, and the list stays CAN-SPAM and GDPR clean.

Segments from CRM

Target any live segment — spend, recency, tags, B2B tier — straight from the CRM. The audience recomputes itself; no export, ever.

Inbox placement

Per-provider delivery to Gmail, Apple Mail, Outlook, and Yahoo, with bounce and complaint rates watched against the thresholds that matter.

Drive it over MCP

Your AI assistant can pull email stats and send a broadcast in plain English — with a confirmation step before anything goes out.

Your domain, your list, your data.

Email runs on the same database as your customers and orders, so every open feeds the CRM and every segment is current. Send from your own domain, keep your own reputation, and pay one flat price no matter the volume.

Email questions.

Deliverability, your own domain, what it costs, and how it fits — answered straight. Still deciding? Read the email docs or start the 14-day trial.

Will my email actually reach the inbox?

Deliverability is the whole point. The moment your domain verifies, sparx authenticates it with SPF, DKIM, and DMARC and signs every message with your DKIM key. Bounce rate is watched against a 2% threshold and spam complaints against 0.1% per domain, with hard bounces and complaints suppressed automatically — the practices that keep a sender out of the spam folder.
