For teams already on AWS

Email automation you actually own

Your AWS. Your sending reputation. Your data. Sequences, segments, and transactional emails — all through your own infrastructure.

Define campaigns in YAML. Deploy via API. Bad neighbours on shared platforms can never hurt you.

Start building How it works

Email infrastructure for product teams

API-first

YAML sequences

Your AWS, your control

Why teams switch to Kraiter

Infrastructure you control. Reputation you own.

Your reputation, isolated

Send from your own AWS SES. Bad actors on shared platforms can never affect your deliverability.

Automation in minutes

Define sequences in YAML. Push to deploy. No clicking through UI wizards for weeks.

Use what you have

Your AWS account already has SES. It's verified and warmed up. We just orchestrate.

No lock-in

Your data stays in your AWS. We're the control plane. Switch anytime.

Real automation

What you can actually build

Not abstract features. Real sequences that convert users, retain customers, and grow revenue.

SaaS Onboarding

Convert signups to active users with a timed drip sequence that adapts to their behaviour.

Built for developers. Owned by you.

Everything you need for email automation, running on infrastructure you control. API-first. Version-controlled. Production-ready.

Your SES, Your Reputation

Send from your own AWS account. Your domain reputation stays yours. A bad actor on our platform can never affect you.

YAML-Defined Sequences

Define drip campaigns in version-controlled YAML. Push to deploy. No clicking through UI wizards.

Smart Segments

Group contacts by properties, events, or engagement. Membership updates automatically as data flows in.

Event-Driven Triggers

Track user actions via API. Events trigger sequences, update segments, and enrich contact profiles automatically.

Full Audit Trail

Every send decision is explainable. Know exactly why an email was sent, cancelled, or failed. GDPR-ready.

Instant Transactional

Send password resets, receipts, and notifications via API. MJML templates with variable interpolation.

Developer experience

Integrate your way

MCP server for AI workflows. TypeScript SDK for type safety. REST API for everything else.

# In Claude Desktop, add to claude_desktop_config.json:
{
  "mcpServers": {
    "kraiter": {
      "command": "npx",
      "args": ["-y", "@kraiter/mcp-server"],
      "env": {
        "KRAITER_API_KEY": "your-api-key"
      }
    }
  }
}
# Then just ask Claude:
"Create an onboarding sequence that sends
a welcome email immediately, then tips on
day 3 if they haven't activated yet."
# Claude will use the MCP server to:
# 1. Create the sequence YAML
# 2. Upload it via the API
# 3. Confirm it's active

Your AWS. Your reputation.

Emails send through your AWS SES account. You own your sending reputation — bad actors on shared platforms can't affect your deliverability.

Fair use: Event tracking, segments, and contacts are included. We'll reach out if usage is significantly atypical. No surprise charges.
