You may now include “just in time” content from external servers in your email messages using the external fetch capability in email template studio. An external authenticated URL can be fetched just before an email is sent, and may return JSON content for use in the template. The content returned from the external URL should be valid JSON and is parsed and available as Liquid variables. You may subsequently include these Liquid variables as content in your messages, or use them in conditional expressions.
Some sample use cases include:
- Perform real-time inventory/product availability checks before message send
- Automatically sign in a user with authenticated links that include a personalized user token on each email link
- Include dynamic content such as as ads, blogs or conditionally display content based on availability
External content fetch is available on all email messages including one-time, recurring, segment & event triggered campaigns. You may read more about this capability on our documentation site. Please reach out to your success team manager if you wish to use this premium feature.
