What are transactional emails?

Emails your users actually expect

Transactional emails are automated messages triggered by user actions—password resets, order confirmations, shipping notifications, account alerts. Unlike marketing emails, users expect these. They have 4-8x higher open rates than promotional emails.

With Sequenzy, transactional emails are first-class citizens. Same deliverability infrastructure, same analytics, same simple API—but purpose-built for time-sensitive, critical messages that must arrive instantly.

Design with AI: Don't want to write HTML? Use Sequenzy's AI email builder to generate beautiful, responsive email templates. Describe what you want, and AI creates the design. Edit visually, then send via API.

// Initialize the Sequenzy client
const client = new Sequenzy({ apiKey: 'your-api-key' });

// Send using a template (recommended)
const response = await client.transactional.send({
  to: 'user@example.com',
  slug: 'password-reset',
  variables: {
    RESET_LINK: 'https://app.example.com/reset?token=abc123',
    USER_NAME: 'John',
    EXPIRES_IN: '24 hours'
