Newsletter Studio replaces the tangle of Word docs, Figma files, freelance developers and endless email threads with one platform: drag-and-drop blocks, AI content, shareable client previews, tracked approvals, compatibility testing and one-click export.
Build newsletters block by block — no HTML, no broken layouts. Every element is built on MJML, the responsive email standard, so what you assemble renders correctly across Outlook, Gmail, Apple Mail and beyond.
Bring content in from wherever it lives — the AI turns it into fully editable email blocks.
Share a live preview link — no login required — and keep every comment, change and approval in one place, tied to the exact version it belongs to.
One AI assistant runs across your whole workflow — generating content, converting images, translating, and reviewing quality — while real-inbox testing catches rendering issues early.
The AI comments on structure and content issues — accessibility, missing alt text, broken hierarchy, tone — reducing manual QA passes.
Instant rendering tests across Outlook 2016–2021, Gmail, iPhone/iPad, Outlook.com, Yahoo, Thunderbird and more.
A complementary test suite for broader client coverage — results link straight back into the app, no tool-switching.
Hand off to your ESP, your developers, or your test clients. Then multiply one newsletter into every language your audience speaks.
Inlined images, ZIP export — paste into any ESP or campaign tool.
Clean source to hand to developers or keep in version control.
Open directly as an email or attach for Outlook & client testing.
Built-in campaign link tagging for clean tracking out of the box.
AI auto-translates every translatable field — headings, text, buttons, alt text, tables, columns, navigation, accordion & carousel captions — with per-element control over exactly what gets translated. The UI itself ships in DE/EN.
Built for agencies and platform teams serving many clients at once. Each client is a fully isolated tenant with its own users, branding, permissions and budget.
A client only ever sees their own Spaces and newsletters — no cross-tenant leakage, ever.
Each SuperSpace gets its own logo and color theme, injected server-side — the app feels like their product.
Ed25519 challenge-response super-admin auth and HMAC-SHA256 integrity-verified project exports.
Every AI-powered or paid action consumes credits, budgeted at the client level and distributed down to each Space — so nobody blows the budget and every cost is traceable.
AI-assisted creation plus built-in compatibility testing removes days of back-and-forth between designers, developers and clients.
Nothing ships without an explicit, tracked sign-off — approver name and timestamp recorded against the exact version.
A true multi-client model: many isolated tenants, per-client branding, role-based access and transparent cost control.
Modular by design — MJML core, pluggable AI and pluggable testing providers make it easy to extend.
See how Newsletter Studio collapses your entire email workflow into a single, AI-native platform — built for teams and agencies who ship a lot of email.
