The most efficient way to use mustache templates with SendGrid: send 1000 mustache mails with only 1 POST request.

Instead of sending 1000 rendered mustache mails (with different html properties) through 1000 POST requests, we map mustache variables to the SendGrid X-SMTPAPI so that the same job is done with only 1 POST request.

npm install sendgrid-mustache

sm.send(email, users, callback)

• email is the same object as in the sendgrid.send(email) method. Additionnally, you can specify a template file with textTemplate and htmlTemplate (instead of using text and html).

• users is an array of JSON objects with an email property and the other mustache parameters.

• callback is a function(success, message, end) called if 1000 emails have been sent or if all emails have been sent. The end parameter is a boolean indicating if it's the latter. For example, if we're sending 3500 mails, the callback will be called 3 first times with end === false for the first 3000 emails and one last time with end === true for the last 500 emails.

  var sm = require('sendgrid-mustache').open({
    user: 'your_api_username',
    key: 'your_api_key'
  });

  sm.send({  
    from: '[email protected]',
    subject: 'Hello {{name}}',
    text: 'You are the president of {{country}}'
  }, [
    {email: '[email protected]', name: 'Francois Hollande', country: 'France'},
    {email: '[email protected]', name: 'Barack Obama', country: 'USA'},  
    {email: '[email protected]', name: 'Angela Merkel', country: 'Germany'}
  ], function(success, message) {
    console.log(success ? 'Emails sent' : message);
  });

Since we use the SendGrid X-SMTPAPI under the hood, this module only supports basic mustache. No sections!
