◇ AI-first email platform

Your email marketing, reborn AI-first.

Everything an enterprise ESP does (journeys, segmentation, dynamic content, deliverability), rebuilt so an AI can drive it, and so you can migrate off your legacy platform without rewriting a single template.

Free sandbox account · Import from SFMC, Responsys, Braze, HubSpot & more

A silver envelope with a neural network emerging from it

The full enterprise toolkit, none of the enterprise pain

SFMC-grade capability without the six-figure contract, the consultants, or the year-long onboarding.

✉️

Journeys & automation

Multi-step, multi-channel journeys with branching, wait steps, and event triggers. Visual, versioned, and testable.

🎯

Segmentation & audiences

Query your data extensions with a real query console, build reusable segments, and preview counts before you send.

🧩

Dynamic content

Personalization that runs server-side and sandboxed: the power of AMPscript with none of the lock-in.

📊

Experiments & analytics

Built-in A/B testing with real statistical significance, plus dashboards for opens, clicks, and journey performance.

🛡️

Enterprise isolation

Multi-tenant by design. Row-level security enforces your data boundary at the database, not just in code.

🚀

Managed deliverability

Send on a managed MTA backbone with domain readiness checks, warmup, and a hard proof-gate before any launch.

◇ Universal import

The off-ramp from every legacy ESP

Paste a template from Salesforce, Responsys, Braze, HubSpot, Marketo, or Klaviyo. SentientScript, our own typed template engine, translates it into one canonical form and renders it byte-for-byte identical to the original.

Verified pixel-perfect against hundreds of real production templates
Six dialects in, one clean language out, no rewrites, no surprises
Anything it can't translate is quarantined, never silently broken

// AMPscript, RPL, HubL, Liquid, Handlebars, Velocity…
%%[ IF Empty(@name) THEN ]%% Hi there %%[ ELSE ]%% Hi %%=v(@name)=%% %%[ ENDIF ]%%

↓ SentientScript

// one typed IR, renders identically everywhere
{ "if": [ isEmpty(name) → "Hi there",
else → "Hi " + name ] }

◇ AI-native

Drive your ESP from any AI

A built-in marketing agent composes emails, builds journeys, and writes personalization for you. And because SentientMail speaks MCP, you can connect it to Claude, Cursor, or your own agents, in the browser or on the desktop.

Bring your own AI: Anthropic, OpenAI, Gemini, Perplexity, or xAI
Pick a different model for each task; your key, your cost, unlimited
In-app AI agent that drafts, segments, and personalizes
Model Context Protocol server for desktop AI clients
WebMCP: agentic browsers drive the app in your own session
Every AI action is scoped and approval-gated: agents draft, humans send

# Connect Claude, Cursor, or any MCP client:

POST /api/mcp
Authorization: Bearer <your agent key>

# the AI can now:
  → compose_branded_email
  → build_journey
  → author_personalization
  → (but never send, that's your call)

Bring your templates. Keep your sanity.
