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',
