Use sample data in the Dyspatch Editor to power dynamic email contentDynamic Email ContentText, links, images, and any other email elements that can change, through programming logic, based on the end user. in your template previews. Sample data is formatted as a JSON object, similar to what your system uses when passing data to a template for rendering.
JSON is a format for representing data with key and value pairs, used to store and exchange data. A JSON key has to be text wrapped in double quotes (e.g. "firstName") and a JSON value can be text, numbers, lists, etc.
Below is an example of a JSON object, with some values: a string "Kieran"
, a number 2
, a list of strings ["sushi","pizza","hash browns"]
and a boolean true
.
{
"firstName": "Kieran",
"pets": 2,
"favFood": ["sushi","pizza","hash browns"],
"nicePerson": true
}
Without sample data, variables will appear in the preview as they are like the @{firstName}
above.
Navigate to the Sample Data tab within the editor to add sample data for your template. Using JSON format, create your sample data. Variables in your template will now be replaced with the values provided by the sample data.
Incorrect formatting of sample data will cause a warning to appear in your Preview Pane, with a description and location of the error. The error in the example above, means the sample data is missing the colon : required to separate the key from its value.
