title: Is it possible to to send bulk pre-rendered email via the SendGrid API?
body: <p>I checked the SendGrid API docs, and didn't find a possibility to send bulk pre-rendered emails. Is this possible?</p>
  
  <p>What I want to do is use my own templating engine to render the individual email content, and then upload these (including recipient, subject and the mail body) as bulk to the SendGrid systems.</p>
  
  <p>I can send transactional mails without a problem, but it's currently too slow for large amounts of mails.</p>
  
  <p>I'm currently using the Node.js library <a href="https://github.com/sendgrid/sendgrid-nodejs" rel="nofollow">https://github.com/sendgrid/sendgrid-nodejs</a></p>
