Why Emailux
Built for content writers & engineers to ship beautiful emails
Marketers/writers creates emails in Studio; engineers spend less glue code on brittle HTML
Reuse templates
Create a template and reuse it across multiple emails.
AI-assisted creation
Use purchased AI credits for prompts inside the canvas.
Schedule sending
Create a campaign for your contacts and schedule sending.
No-code canvas
No-code canvas frees marketers/writers from layout tickets; pairing it with reusable templates also shrinks repetitive HTML tweaks for engineers on campaign work.
Design studio + APIs for your Email backend
EmailUX is a complete email platform that allows you to create/update emails without engineering, and use those emails for marketing campaigns, or connect your platform's backend to trigger render or send with your own ESP.
Responsive email HTML
Output layout-focused HTML suited for responsive emails and Email Studio previews — your ESP inbox placement still depends on your reputation.
Localization built-in (Pro)
One template translated into multiple locales (including RTL) — choose locale at render or send time.
Logical placeholders
Create conditional contents placeholders and other placeholders in the email.
Advanced Usage
EmailUX SDK
Use EmailUX SDK, and create your own emails templates for free.
STEP 01
Install the SDK
Open source, JavaScript, TypeScript.
$npm install@emailux/components
added 1 package · open source
STEP 02
Compose with React
Build emails as components. Reuse, theme, ship.
import { Html, Body, Text } from "@emailux/components"
export const Welcome = () => (
<Html><Body>
<Text>Hello world</Text>
</Body></Html>
)
STEP 03
Deliver
Render HTML in your codebase, reuse it with your tooling, or queue a Deliver API call so EmailUX hands off to SendGrid/Google/SMTP/IMAP setups while your credentials remain in control.
import { getHtml } from "@emailux/components"
import { Welcome } from "./emails/welcome"
const { html } = getHtml(<Welcome />)
await sendEmail({ html })

About EmailUX
Email UX (dba EmailUX) is a self-service platform built and operated by iClasser LLC in the San Francisco Bay Area for marketers, content writers, and developers who want to spend less time wiring bespoke responsive email HTML. Email Studio covers visual iteration; stored templates, render/deliver APIs, npm @emailux/components, and optional @emailux/api-client shrink engineering work feeding your ESP. Campaigns add CSV lists, filters, scheduling, plain-text sends with AI help, unsubscribes, App Contacts for REST CRUD, and triggers that always use your encrypted ESP credentials.
EmailUX is bring-your-own ESP: connect Google Workspace, SendGrid API keys, or SMTP/IMAP (including Gmail and Yahoo mailboxes), then send from the product or automate with the API — always through your credentials. It is not an ESP. Localization includes right-to-left languages such as Arabic and Hebrew; choose locale at render or send time. The AI assistant is available with Email Studio Pro plus purchased AI credits.
Developers can install @emailux/components for free to compose React email without Email Studio — documentation at docs.emailux.com — and optionally use @emailux/api-client TypeScript helpers for render and deliver calls against stored Email Studio templates on your ESP.
Capabilities
- Email Studio (self-service): visual editor to build email layout — sizing, backgrounds, borders, drag-and-drop text/images/lines/shapes — save a template ID, then trigger via platform or API. Not a managed design service.
- Marketing: import/edit contacts from CSV; filter lists; schedule campaigns from studio templates or plain-text emails (with AI from credits); optional unsubscribe link per send; sync contacts through App Contacts via API keys and documented REST routes for CRUD.
- Render/deliver API: HTML from stored templates plus your data — render for pipelines or queue a deliver call through your connected ESP in one authenticated request while mail continues to egress from your provider reputation.
- Localization and right-to-left support: author one template, translate into locales (example en-US, fr-FR, es-MX, ar-SA) and choose at render or send time — fully supported RTL for Arabic and Hebrew.
- Open-source library: free
@emailux/componentsnpm package for React email primitives (Html, Head, Font, Body, Img, Text, Card, Table, Button) plus getHtml renderer without buying Email Studio. - Enterprise engagements: bespoke limits, integrations, routing, SLA, and onboarding — coordinated with EmailUX; excludes agency creative work on your behalf unless separately contracted.
Design email, trigger sends through your existing ESP
EmailUX combines Email Studio, render/trigger APIs, npm @emailux/components and @emailux/api-client for developers who reuse stored template IDs (experience IDs) instead of hand-maintaining brittle layouts, Email Studio Pro AI assistant (requires AI credits), full localization including right-to-left Arabic and Hebrew, and marketing campaigns with CSV imports, schedules, App Contacts REST CRUD, unsubscribes, and BYO connectors for SendGrid, Google Workspace, or SMTP/IMAP including Gmail/Yahoo mailboxes—credentials encrypted at rest—so marketers, writers, and engineers iterate without EmailUX pretending to operate as sender-of-record. Your ESP handles delivery, warming, and bounces; /guides explains sender education. EmailUX does not sell domains, run warmups, fix DKIM for you, provide bounce tracking, source contacts, redesign emails like an agency on retainer by default, or ship managed MTAs. Open tracking may be offered in future.
