// Include the OMS library and add the API Key
const MailPace = require('@mailpace/mailpace.js');

const fs = require('fs');
const file_buffer = fs.readFileSync('image.jpg');
const contents_in_base64 = file_buffer.toString('base64');

// Craft the email
const email = {
  from: `test@yourdomain.com`,
  to: 'person@address.com',
  subject: 'Attachment Email',
  htmlbody: '<p>There is an attachment attached!</p>',
