Sendgrid handlebar template array length

I'm trying to fetch length of an array but it seems length only exists for conditionals.

Data:

{
    "array": ["a", "b", "c"]
}

in sendgrid template:

{{array.length}}

and nothing is rendered in the email (preview renders it correctly).

Is there a workaround for this?

Solution

  • it looks like you can use the greaterThan tag

    Example from Sendgrid docs:

    <p>
Hello Ben!
{{#greaterThan (length cartItems) 0}}
