Add Dynamic Content in Marketing Campaigns Templates

Twilio SendGrid Marketing Campaigns allow users to add dynamic content to their templates. This is achieved using greaterThan with else and length helpers. These allow you to iterate through a string or array. Here's some example code of what this might look like:

<p>{{#greaterThan (length newsletter_items) 0}}
