Send with the Sequenzy SDK
npm install sequenzy
import Sequenzy from 'sequenzy';

// 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'
  }
});

// Or send with custom content (no template needed)
await client.transactional.send({
  to: 'user@example.com',
  subject: 'Password Reset Request',
  body: '<h1>Reset your password</h1><p>Click the link below...</p>',
  variables: {
    USER_NAME: 'John'
  }
